[0002] The invention relates in general to powered watercraft and, in particular, to motorized marine riding board systems and components.BACKGROUND

[0003] In the last few years, there has been increased use of powered marine riding boards or surfboard systems for commercial and recreational marine applications. These systems typically are not energy efficient and produce a lot of noise and vibrations. Electric motorized systems partially address these concerns, but they have some disadvantages which make their use optimal only for a limited speed range and which limit the overall propulsive efficiency. Thus, there is a need to modify a conventional motorized riding board or surfboard with the aim of reducing these problems and increasing the overall user experience.SUMMARY

[0004] In response to these and other problems, in one embodiment, there is a flexible motorized riding board system that can be configured for multiple situations and user preferences.

[0005] These and other features and advantages will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings. It is important to note the drawings are not intended to represent the only aspect of the invention.BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Fig. 1 A is an isometric top view illustrating one embodiment of a motorized marine riding board or “surfboard” system 100 looking from the top front port perspective. In contrast, Fig. 1 B is an isometric top view of the motorized marine riding board system or board 100, looking from the rear port perspective. Fig. 1 C is an isometric partial exploded view illustrating certain hull components.

[0041] Turning now to Figs. 1 A, 1 B, and 1 C, in certain embodiments, the motorized marine riding board system 100 is a flexible system that can be configured for various purposes and needs, as discussed below. In certain embodiments, there is a hull 102 having a top portion 104 and a lower portion 106. In certain embodiments, the hull portions 104 and 106 are formed from fiberglass layers. The top portion 104 along with defines a flat surface 108, which comprises much of the top portion of the hull 102. As will be explained later, there may be a plurality of attachment points rising from this flat surface, which allows for the coupling of different accessories and configurations. In certain embodiments, there may be a thin sheet or layer of foam 110 or rubberized material, such as ethylene vinyl acetate (“EVA”) positioned over the flat surface 108 and / or much of the top portion 104 to protect the hull 102 from UV rays and to provide some comfort to the user.Battery Box:

[0042] Fig. 1 D is an exploded view illustrating certain components of the board 100. In certain embodiments, the top portion 104 of the hull 102 defines a battery compartment 1 12 for housing a replaceable power source, such as a battery 1 14. A removable lid 1 16 seals the battery compartment 112 and prevents an excessive amount of water from entering the battery compartment. Removal of the lid 1 16 allows a user to charge or replace the battery 1 14 when necessary. In certain embodiments, a pair of handles 118 allow the user to lift the battery 114 out of the battery compartment 112 with relative ease. In other embodiments, the battery is not removable and may be charged inductively or by a direct connection through the hull (not shown).Nose Cone:

[0043] In certain embodiments, a control module 120 may be positioned at the bow or front of the board 100. In certain embodiments, the control module 120 may be removable and include a waterproof housing containing various electrical components and interfaces. In certain embodiments, the control module includes one or more distribution printed circuit boards or distribution PCBs to channel power from the battery 114 to multiple components and devices. Additionally, the distribution PCBs routes signals between various components in the circuit, such as data signals, control signals, and other forms of communication over RS485 connections, WIFI, Bluetooth, and other wired or radio signals.

[0044] As an example, in one embodiment, the control module 120 might include a radio and distribution PCB for communicating with a tethered throttle (not shown) and / or inductive charging pads (not shown). In certain embodiments, the distribution board may include a WIFI radio or use RIFD signaling to communicate with the tethered throttle or throttle key.

[0045] In yet other embodiments, there may be an additional distribution PCB for communicating with throttles, optional handles or an Electronic Speed Controller or ESC (not shown) for the motor. In certain embodiments, the control module 120 includes aGPS module, a communication interface (including VHF radio, WI-FI for telemetry, and Bluetooth for interfacing the user devices, such as headphones), shut-off systems, and circuit breakers / fuses. In yet other embodiments, there may be inductive charging pads and power delivery devices for user devices, such as headphones or wireless phones.

[0046] In certain embodiments, there may be a wireless or inductive charging system within or adjacent to the control module 120, which allows for a wireless and wired charging output to power accessories for the board. The control module 120 may also have an inductive receiver which allows a charging station (not shown) to inductively charge the main battery 1 14 when the battery is positioned within the battery compartment 112.Propulsion System:

[0047] Fig. 2 illustrates a perspective view of the board 100 from a bottom or lower perspective showing the lower portion 106 of the hull 102. A jet intake or water valve intake 131 defined in the lower portion 106 of the hull 102 allows water to flow through a jet propulsion or jet pump system 130 (see Fig. 3A and 3B). The jet pump system 130 is positioned towards the rear or stern of the hull 102 and expels water entering the water valve intake 131 through a nozzle 134 (see Figs. 3A-3C) creating a forward thrust. Certain embodiments of the jet pump system 130 may include a shaftless motor having a water-cooled system (not shown). For more information regarding the jet pump system 130, see U.S. Provisional Application 63 / 462,289, entitled “Jet Pump Propulsion System,” filed on April 27, 2023; U.S. Application 18 / 811 ,31 1 , entitled “Jet Pump Propulsion System,” filed on April 21 , 2024; U.S. Provisional Application 63 / 459,534, entitled “Caseless Electric Motor with a Stationary Shaft,” filed on April 14, 2023; U.S. Application 18 / 811 ,160, entitled “Caseless Electric Motor with a Stationary Shaft,” filed on August 21 , 2024; the specification of all Applications are herein incorporated by reference for all purposes. As best indicated in Fig. 1 C, the lower portion 106 of the hull defines an enclosure 107 for the jet pump system 130.

[0048] Fig. 3A is a section view of the hull 102 and various components positioned within the hull including the jet pump system 130. Fig. 3B is an exploded section view of thehull 102 showing the jet pump system 130 and a ride plate 132 removed from the hull. Fig. 3C is a detailed section view of the stern end of the hull 102, the jet pump system 130 and the ride plate 132 and shows the interaction between the hull, the pump system, and the ride plate in an assembled configuration.

[0049] In certain embodiments, the jet pump system 130 may be relatively easy to remove for maintenance. Turning to Figs. 3A-3C, if the user wishes to remove the jet pump system 130, the user may remove a plurality of fasteners, such as finger or thumb screws (not shown). In other embodiments, the screws (not shown) may be removed with a torque-inducing device, such as a screwdriver (not shown). In certain embodiments, the user first removes the ride plate 132, which is best illustrated in Figs. 2, 3B and 3C. After the ride plate 132 is removed, the jet pump system 130 can then be pulled in a longitudinal direction (as illustrated by arrow 310) towards the stern of the hull 102 until the jet pump 130 reaches a predetermined position and the electrical connections (not shown) are disconnected. At this time, the entire jet pump system 130 can be lifted out from the hull 102 in a direction illustrated by arrow 312. This “slide in” and attachment system for the jet pump allows for a foil and future accessories (flat surfaces and attachment points) to slide in when the jet pump slides out.Fins:

[0050] As illustrated in Fig. 2, in certain embodiments, the underneath of the hull 102 includes fin attachment points that allow fins (not shown) to be inserted and / or removed. In certain embodiments, there is a center or main fin attachment coupler 202 and two side fin attachment couplers 204a and 204b. In certain embodiments, the center fin attachment coupler 202 is coupled to the ride plate 132 and has a longitudinal slot or keyhole for removably engaging a center fin (not shown). In certain embodiments, the side fin attachment couplers 204a and 204b have dual engagement slots or keyholes which allow for different positioning of the side fins or the use of two side fins on each side of the hull 102.

[0051] Once the fin has been placed into a keyhole or slot in the center fin attachment coupler, the fin may be slid in a forward direction to the forward-most point in the channelor keyhole. At this point, the tail end of the fin may be pressed securely into a corresponding groove. When done correctly, a connector, such as a finger screw (not shown) on the back of the main fin, should be able to be screwed into the ride plate, locking the main fin in place. The side fins may also be inserted into the side couplers 204a and 204b by sliding a front hook end of the side fin into the side coupler slot and pushing the fin to its forward-most point before pushing the side fin down and locking it in place. Thus, the fins may be inserted and removed without the necessity of tools.Accessories and Configurable System:

[0052] Operating the board 100 from a standing position may require practice and training. Until the user is experienced, there may be issues with controlling the direction and speed of the board - especially when the board is close to the shore or other watercraft. So, some form of protection may be advisable. Other users may prefer to operate the board from a kneeling or sitting position which requires less skill but requires a different type of control system. The board 100 is designed to accommodate a wide variety of user’s needs by being part of a system that can accommodate a wide variety of situations through the use of interchangeable accessories. Fig. 4 is an exploded view of the board 100 illustrating some of the accessories designed to be paired with various configurations of the board. For instance, experienced users may prefer to use a single tethered control handle 500, passive handles 514, and foot pads 552 and 554. In contrast, an inexperienced user may prefer active control handles 700, a knee pad 750, and a training tube 800. Additional accessories may include a training tube 800 and / or a transport system, such as a wheel system 900, and an additional protective system 1000 (see Figs. 10A and 10B). Such accessories and configurations will be discussed below:Controller / Throttle Embodiments:

[0053] Fig 5A is a perspective view illustrating the front for the board 100 coupled to tethered control handle 500 which controls the motor speed in certain embodiments. Fig. 5B is a detailed perspective view of the tethered control handle 500. In certain embodiments, the handle 500 may be supplied with an activation key 502. When the key 502 is inserted into the handle 500, the electronics inside the board may be activated. Anindicator, such as an indicator light that turns green can signal to the user that a battery charge up test has been performed by the circuity discussed above and that the battery level is sufficient and the system is ready for use. In other embodiments, there may also be a battery indicator display 504 built into the handle 500 so that the user can determine the level of battery charge and whether the system is ready for use. This display 504 can also signal to the user that the battery level is critically low so that the user can return to the shore and not get stranded in the water.

[0054] In certain embodiments, the activation key 502 may be coupled to a wristband (not shown) worn by the user for safety reasons. For instance, if the user falls off of the board 100, the key 502 if attached to the user’s wrist will be pulled out of the handle 500, and the motor will switch off automatically. The board 100 will quickly stop the forward movement of the surfboard, which not only enables the user to return to the board, but also prevents the board from continuing its forward movement, which might lead to its damage, damage to other vessels, or injuring other people, including the user.

[0055] In certain embodiments, a throttle trigger 506 is situated on the handle 500 which the user to control the speed of the motor with the user’s finger, such as an index finger. When the throttle trigger 506 is pressed, the speed of the motor increases. When the trigger 506 is released, the motor stops or slows down and the board 100 decelerates.

[0056] In certain embodiments, the handle 500 may communicate to the board’s control system via a wired communication cable 508 as discussed above via an electrical connection 512 incorporated into the control module 120. In other embodiments, the handle 500 may communicate with the control module 120 via a wireless means discussed above. In either case, a tether line 510 is usually necessary for the user’s stability while standing on the board 100. Thus, in the illustrative embodiment, the tether line 510 is employed for structural / stability reasons while communication signals are transmitted through the communication cable 508. In other embodiments, the tether line 510 may also include internal wires for signaling and / or power.

[0057] In the situation illustrated in Figs 5A and 5B, the board 100 may be equipped with removable “passive” handles 514 that are designed to allow the user to move andmanipulate the board. In this illustrative configuration, the passive handles 514 do not have throttle controls because throttle control is performed by the control handle 500 discussed above. The passive handles 514 and active handles 700 described below are “removable” so that the user can easily configure the system 100 as desired. The term “removable,” as used in this specification, refers to components that can be removed by the user using a minimum of tools (or no tools at all).

[0058] Fig. 5C is an isometric illustration of the board 100 that has been configured for a user in a standing position. Note that in Fig. 5C, the layer of foam 110 has been removed for purposes of clarity. Because the user will be standing, the board 100 is coupled to the tethered control handle 500 as discussed above. The board 100 has also been equipped with a left footpad 552 and a right footpad 554 to provide stability for the user’s feet. Although Fig. 5C illustrates a configuration where the left footpad 552 is towards the bow and the right footpad 554 is positioned towards the stern, the footpads are highly configurable and may be placed in alternative locations. Thus, in an alternative arrangement, the left footpad 552 may be placed towards the stern and coupled to anchor points 558. Additionally, the right footpad 554 may be placed towards the bow and may be coupled to the anchor points 602.

[0059] The footpads 552 and 554 are adjustable to accommodate a user’s foot and can be adjusted from the bottom side of the footpad base plate. They can be adjusted by loosening or tightening with hook and loop straps and / or the paracord support lines (not shown). Once correctly adjusted to size and the paracord ends properly tucked into place, the entire footpad assembly (base plate and straps) may be mounted onto the top of the board, as shown in Fig. 5C. In certain embodiments, the footpads 552 and 554 can be slid into position and then an additional securing mechanism, such as a finger or thumb screw, can be used to secure the footpad to the board 100.

[0060] In certain embodiments, attachment points may be designed to mate with couplers and / or openings defined on the bottom surface of the various accessories. In certain embodiments, the attachment points may be magnetic or mechanical studs or posts. Corresponding openings on the bottom of various attachments may have amagnetic or ferrous metal backing to magnetically couple to the magnetic or ferrous posts when the posts are captured by the opening. In other embodiments, the posts or studs may be headed posts designed to be captured by corresponding slots defined upon the bottom surfaces of the various accessories. In such embodiments, the accessory first engages the headed stud vertically to capture the head, then slides over the stud into place. The head of the stud is captured by a slot in the defined in the bottom of the accessory. In certain embodiments, there may be electrical connectors, such as an RJ485 connector which allow various “smart” accessories to be electrically connected to the electronics within the board in addition to being connected to the flat surface of the board 100.

[0061] Fig. 6A is a perspective view of a non-magnetic attachment post 602, which can be used to couple the footpads 552 or 554 (not shown) to the top portion 104 of the hull 102 (Not shown in Fig. 6A). In this embodiment, the attachment post 602 has a center shaft 601 and an enlarged circular head 604 and circumferential groove or recess 606 defined around the perimeter of the head which allows a matching detent 560 (see Fig. 6D - defined on a coupling portion 562 of the footpads 552 or 554) to slidingly engage the attachment post 602.

[0062] Fig. 6B is a detailed isometric view of a portion of the hull 102, which is under the footpad 552 shown in Fig. 5C. In Fig. 6B, the footpad 552 has been removed for clarity, and the top portion 104 of the hull 102 is transparent so that a supporting bracket 614 can be illustrated. In certain embodiments, the supporting bracket 614 may be made of metal, such as titanium. In Fig. 6B, the supporting bracket 614 is shown coupled to four attachment posts 602a, 602b, 602c, and 602d. In certain embodiments, the threaded shank 601 of the screws 602a-602d go through the carbon fiber of the hull 102 (not shown) and through apertures defined in the supporting bracket 614 to engage retaining nuts (not shown - such as titanium acorn nuts) positioned underneath the supporting bracket 614. In certain embodiments, the retaining nuts (not shown) may be welded to the support anchor bracket to prevent backout.

[0063] Fig. 60 is a perspective view of the footpad 552 positioned over the attachment posts 602a-602d, which are coupled to the anchor bracket 614. In Fig. 6C, the top hull portion 104 of the hull 102 and the layer of foam 1 10 have been removed for clarity. As illustrated in Fig. 60, the bottom of the footpad 552 has four couplers 562a through 562b, sized and spaced to slidingly engage the four anchor posts 602a-602b. Fig. 6D is a detailed perspective view of one such coupler 562a. Thus, when a user wishes to couple the footpad 552 to the board 100, the user can position the couplers 562a-562d adjacent to the corresponding anchor posts 602a-602b and then slide the couplers into position. In certain embodiments, a separate attachment mechanism, such as a thumb screw (not shown), can engage a threaded aperture 622 defined in the anchor bracket 614 to provide for an additional means of fixation.Active Handles:

[0064] In certain situations, a user may prefer to operate the board 100 from a kneeling or sitting position. In such a situation, the single tethered control handle 500 may not be practical and / or desirable. Fig. 7A is a perspective view illustrating an alternative configuration where the front of the board 100 is coupled to two “active control” handles 700, which control the motor speed. Fig. 7B is a perspective view illustrating the configuration of Fig. 7A where the active control handles 700 have been removed for clarity.

[0065] In certain embodiments, the user may be supplied with an activation key (not shown) similar to the single tethered control handle described above. In such configurations, the key may be inserted into one of the handles 700 or directly into a port within the control module 120 or the hull 102. In other configurations, the key may be linked to the control module 120 via Bluetooth, RIFD, or another wireless transmission links as discussed above. In such configurations, the board 100 becomes activated either when the user is in close proximity to the board and / or the user hits a trigger or button on the board (not shown) to activate the board while the key is in proximity to the board. An indicator, such as an indicator light that turns green can signal to the user that a battery charge up test has been performed by the circuity discussed above and that the batterylevel is sufficient and the system is ready for use. In other embodiments, there may also be a battery indicator display 702 built into the control module 1 0 so that the user can determine the level of battery charge. This display 702 can also signal to the user that the battery level is critically low so that the user can return to the shore and not get stranded in the water.

[0066] In certain embodiments where a wireless link is established between the board 100 and the activation key (not shown). The activation key in this embodiment may also be coupled to a wristband (not shown) and worn by the user for safety reasons. For instance, if the user falls off of the board 100 and the wireless link is broken or the sytem indicates that there is a predeterimined distance between the user and the board 100, the motor will switch off automatically. The board 100 will quickly stop the forward movement of the surfboard as discussed above.

[0067] In certain embodiments, throttle triggers 704 are situated on the handles 700 which allows the user to control the speed of the motor with the user’s finger, such as an index finger. When one of the throttle triggers 704 are pressed, the speed of the motor increases. When both triggers 704 are released, the motor stops or slows down and the board 100 decelerates. In certain configurations, a “one-handed” operation of the board 100 is possible because pressing on either one of the throttle triggers 704 cause the speed of the motor to increase.

[0068] Fig. 7B shows handle gaskets 712 and electrical connections 710 defined within the hull 102 of the board 100. The handle gaskets 712 and connector spacings are sized so that either the passive handles 514 or the active handles 700 may be used with the various configurations of the board 100. In configurations where the active handles 700 are not used, the handle gaskets 712 keep water out of the electrical connections 710. Additionally, the bottom of the passive handles 514 may have grommets made of flexible material shaped and sized to mate with the connectors 710 - which will also assist in keeping water from entering the electrical connectors 710.

[0069] In certain embodiments, the handles 700 may communicate to the board’s control module 120 via a wired communication cable (not shown) running beneath the hull 102from an electrical connector 710 (Fig. 7B) to an electrical connector (not shown) on the control module 120. In other embodiments, the handle 700 may communicate with the control module 120 via a wireless means discussed above. In such embodiments, the handles 700 may have their own power supply (not shown) which may be charged either wired or wireless by the main power supply or battery 114.

[0070] Fig. 7C is an isometric illustration of the board 100 that has been configured for a user in a kneeling position. Fig. 7D is an isometric illustration of a removable knee pad 750. Because the user will be kneeling during operation, the board 100 is coupled to the active control handles 700 discussed above. For the user’s comfort, the board 100 may also be equipped with the removable knee pad 750.

[0071] In the configuration illustrated in Figs. 7C and 7D, the rider kneels on the knee pad 750 and controls the system or board 100 through the use of active handles 700. In certain embodiments, the upper or user side of the knee pad 750 defines two large longitudinal channels or grooves 752 which will accommodate the knees and legs of various size users. The channels 752 provide some stability for the user from lateral forces as well as providing an overall comfortable experience. In various embodiments, the knee pad 750 may be made from a plastic or foam base (such as Nylon or polycarbonate) with a layer or coating of ethylene vinyl acetate (“EVA”) to protect the foam from UV radiation. The plastic structure may be hollow or have structural ribs supporting the top surfaces of the knee pad 750. The area between the ribs may be hollow or filled with a lightweight foam.

[0072] In certain embodiments, there may be a removable adjustable strap 756 (Fig. 7C) which is designed to help stabilize the user. The strap may attach to the knee pad via a hook and loop system either on the sides and / or bottom of the knee pad. In some embodiments the strap 756 is positioned completely under the knee pad 750 and then wraps over the user’s legs. The ends of the strap are secured to each other by a hook and loop system or another quick release system. In yet other embodiments, there may be two straps - each secured to the edges or bottom of the knee pad 750.

[0073] Fig. 7E is an isometric illustration of the bottom or connecting side 760 of the knee pad 750. As illustrated, there may be a number of elongated slots 762 formed on the underneath face of the knee pad 750. Some or all of these slots may include embedded couplers 764 - similar to coupler 562 described above in reference to Fig. 6D. The elongated slots 762 are sized and positioned to accommodate the attachment posts 602 for the footpads described above. Thus, when a user wishes to couple the knee pad 750 to the board 100, the user can position the knee pad so that the embedded couplers 764 are adjacent to the corresponding anchor posts 602 and then slide the knee pad 750 into position. The embedded couplers 764 will couple to the anchor posts 602 and retain the knee pad 750 in position as described above in reference to the foot pads. In certain embodiments, a separate retaining mechanism, such as thumb screws 754 (Fig. 7C) can go through apertures 768 defined in the base of the knee pad 750 to engage threaded apertures 622 (see Fig. 6C) of the anchor bracket 614 positioned below the hull 102 to provide for an additional means of fixation.Training Tube:

[0074] In certain configurations, illustrated in Fig. 8A, a detachable “training tube” 800 may be provided to reduce the likelihood of damage if the user collides with another board, boat or some other object on and off the shore. Fig. 8B is an exploded view of the embodiment illustrated in Fig. 8A.

[0075] As can be seen in Figs. 8A and 8B, in certain embodiments, the training tube 800 can be removably attached to an attachment means 802 which, in certain embodiments, can be permanently attached to sides of the hull 102. In certain embodiments, the attachment means may be a cage or frame 804 made from multiple longitudinal components sized to match the exterior of the hull 102. The frame 804 may be coupled to one side of a zipper 806. The zipper 806 has one side attached to the frame 804 and the other side is attached to an inner face of the training tube 800. Thus, to attach the training tube 800 to the hull 102, the user closes or zips the zipper 806 around three sides of the hull. Similarly, to remove the training tube 800 from the hull 102, the user unzips the zipper 806.

[0076] In other embodiments, the attachment means is a hook and loop engagement system, a plurality of pairs of press snap fasteners, buttons, or strips of temporary adhesive. In yet other embodiments, the attachment means 802 may be an adhesive to permanently attaching the tube 800 to the hull 102. In yet other embodiments, a nonpermanent adhesive may be used so that the tube 800 may be removed from the board after the user feels confident to use the board 100 without the tube.

[0077] In contrast to prior art, the illustrated training tube 800 does not have a skirt which fits underneath the hull 102 as with the prior art. When the system is moving, water flows under the bottom of a moving board and creates a suction. So, a vortex or negative pressure area is created underneath the hull 102. When a skirt is used, the skirt will contribute to a drag on the entire system - which will slow the speed of the system as well as being inefficient. In contrast, the illustrated embodiment of a training tube 800 does not have a skirt and thus significantly reduces any drag on the system 100.

[0078] In certain embodiments, the illustrative training tube 800 comprises an inflatable U-shaped tube which becomes compact when not in inflated. If a zipper 806 is used as the means of attachment, one half of the zipper may be permanently attached to the tube. Thus, when a user removes the tube 800 from the board 100, the tube can go into a case (not shown). When the tube if folded out and ready to be used, it can be connected to the board by the zipper 806. The tube 800 may be inflated either before or after it is attached to the hull 102. In alternative embodiments, the tube 800 may be bolted to the hull 102 for a more permanent attachment (i.e., for rescue applications).

[0079] In sum, when the tube 800 is only attached to the outside of the hull 102, the underneath side of the hull is still clean and glides past the water without any resistance from a skirt - which allows the board 100 to accelerate faster with the tube 800 than by conventional systems training or tube systems.Removable Wheels:

[0080] In certain applications, the board 100 might have to be transported over relatively large portions of the shore. Although the board 100 is designed to be a lightweightsurfboard, the size and weight may be unwieldy for certain users when carried over land. Consequently, a removable wheel system 900 may be provided to assist the user in transporting the board 100 over the land or at the shoreline.

[0081] Fig. 9A is an isometric view of the board 100 configured with a knee pad 750 and active handles 700 (see Fig. 7C), but taken from the perspective of the stern and with the addition of a removable wheel system 900. Fig. 9B is a detailed view of the stern of the board 100 showing the connection between the wheel system 900 and the board 100. Fig. 9C is an exploded view of the wheel system 900 and the stern of the board 100. Although the wheel system 900 will be discussed in reference to the illustrated configuration, the wheel system can also be used with any configuration discussed above including when the board 100 is configured with foot pads 552 and 554 and the tethered control handle 500 as illustrated in Fig. 5C.

[0082] Turning now to Figs. 9B and 9C, in certain embodiments, the removable wheel system 900 comprises a pair of removable wheels 902a and 902b, an axle 904, an axle positioner system (such as two cotter pins 906a and 906b, and wheel locks 908a and 908b. In certain situations, the user can transport the board 100 to the shoreline using the wheel system 900 coupled to the board as illustrated in Figs. 9A and 9B. When the user reaches the desired location, the user can easily remove the wheel system 900 from the board 100. To remove the wheel system 900, the user may remove the cotter pins 906a and 906b from corresponding apertures defined within the axle 904. When the wheel system 900 is coupled to the board 100, the cotter pin apertures (not shown) and corresponding cotter pins 906a and 906b are positioned adjacent to the ride plate 132 along the axle 904 which keeps the axle from laterally shifting relative to the board 100.

[0083] The user may also release one of the wheel locks 908a or 908b and, then, slidingly remove the corresponding wheel 902a or 902b from the axle 904. The user may repeat the process for the corresponding wheel and then slidingly remove the axle 904 from corresponding apertures defined within the ride plate 132. In certain embodiments, the wheels 902a and 902b are completely removable from the axle 904 for ease of storage and maximum flexibility.

[0084] After use when the user is ready to transport the board away from the water, the user may reverse the process described above.Enhanced Protection:

[0085] Fig. 10A is a perspective illustration of the bottom of the board 100 with an enhanced protection system 1000. Fig. 10B is an exploded view of the board 100 and enchanced protection system 1000. In certain situations, the board 100 might go over shallow shore lines, debris and other obstacles. For this reason, in certain embodiments there may be a protective skid plate 1002 running almost the entire length of the board 100. In certain embodiments, the protective skid plate 1002 may be made of ultra high molecular polyethylene or the like coupled to the center of the bottom portion 106 of the hull 102 to protect the hull - which may be made out of a less durable material - such as carbon fiber. Additionally, for safety and other reasons, there may be an inlet grate 1004 to keep objects out of the water valve intake 131 of a jet pump system 130 discussed above. In certain embodiments, the protective skid plate 1002 may also be coupled to the fin attachment coupler 202 discussed above in reference to Fig. 2 (not shown in Figs. 10A or 10B).Rescue Board:

[0086] As discussed above, the board 100 is a highly configurable system that can be adapted to a wide variety of situations and user preferences. For instance, certain configurations of the board 100 may be used as a rescue craft, which allows a lifeguard or another rescue professional to quickly access someone who is in trouble (e.g., a “rescuee”). Although the board 100 may be configured to become a rescue craft with the accessories discussed above, certain enhancements to the accessories listed above may make the board 100 even more suitable for rescue operations. These enhancements will be discussed below.

[0087] Fig. 11 A is a top isometric view of an alternative marine riding board system or board 1 100. Fig. 1 1 B is a bottom view of the alternative marine riding board system 1 100. Fig. 11 C is an exploded top view of the configuration of Fig. 11 A where certain uniquecomponents of this embodiment are shown exploded away from the hull 102. For brevity and clarity, a description of those parts and components that are identical or similar to those described in connection with the embodiments illustrated and discussed above will not be repeated here. Reference should be made to the foregoing paragraphs with the following description to arrive at a complete understanding of this illustrated embodiment.

[0088] In this embodiment, a protective tube 1 150 may be affixed to the sides of the hull 102. As opposed to the inflatable training tube 800 of Figs. 8A-8B, in certain embodiments, the protective tube 1150 may be designed to be permanently affixed to the sides of the hull 102 or the rail via an adhesive or other means of attachment, such as snaps or buttons. In certain embodiments, the protective tube 1150 may be formed from a PVC inflatable dropstitch material which is much heavier and stiffer than the training tube material 800 discussed above. In other embodiments, the protective tube 1150 may be formed from a hard plastic tube or Styrofoam. In some embodiments, the protective tube 1 150 has a plurality of handles 1 152 along the top or sides of the tube to allow one or more rescuees to more easily grab hold of the board 1100 in a rescue situation.

[0089] In the illustrated embodiment, the emergency responder uses active handles 700 (described above) to accelerate and control the board 1 100. In this embodiment, the responder may also kneel or lay on a top pad 1 180, which, in certain embodiments, may be placed partially or completely over the entire top surface of the hull 102. The top pad 1 180 may also be formed from EVA, as discussed above. In certain embodiments, the top pad 1180 may be affixed to the top surface of the hull 102 - which prevents access to the battery box (not shown). In certain embodiments, the board 1100 may be equipped with two batteries (not shown) to provide redundancy in emergency situations. Furthermore, in some situations, the batteries may be inductively charged by being positioned to an inductive charging system (not shown) which may be part of a rescue board storage rack so that the boards 1100 are fully charged and ready to go during an emergency situation.

[0090] In certain situations, the board 1100 might have to be transported over relatively large portions of the shore. Consequently, a wheel system similar to the system 900described above can be coupled to the stern of the hull 102, as illustrated in Figs. 1 1 A and 11 B. In certain embodiments, wheels 1190a and 1190b are the same diameter as the protective tube 1150, so the wheels 1190a and 1190b just skim across the water when in use. In certain embodiments, the wheels 1 190a and 1190b may be permanently affixed to the hull 102. In other embodiments, the wheels 1 190a and 1 190b may be removable as discussed above in reference to Figs. 9A through 9C.

[0091] In emergency situations, the board 1100 might go over shallow shore lines, debris and other obstacles in order to locate a rescuee. For this reason, in certain embodiments, a protective skid plate, such as the protective skid plate 1002 and an inlet grate 1004 may be coupled to the bottom portion 104 of the hull 102 as described above in reference to Figs. 10A and 10B.

[0092] In rescue situations, the systems or boards 1 100 may need to be placed in a convenient location so that a rescuer can easily access the boards during an emergency. On the other hand, for security reasons, the boards 1100 should not be accessible to anyone who may have access to the boards or the board storage racks. In certain, embodiments, the rescuer may have an RFID transmitter attached to a wristband, lanyard or some other wearable item that allows the rescuer to “unlock” the board from a locked storage and charging rack. In other embodiments, a removable control module 1140 (similar to the removable control module 120 discussed above) can be inserted into the board to “wake” or start-up the board. Obviously, the board 1100 would not be functional without the removable control module 120. Thus, this configuration allows for the placement and storage of the boards 1100 in less secure and public areas.
