In the second configuration, the second platform 46 is extended along a first axis 74 with respect to the first platform 30. In the illustrated embodiment, the first axis 74 is parallel to the center bow-stern axis 18. In some embodiments, the first axis 74 is coaxial with the center bow-stern axis 18. In other words, in the illustrated embodiment, the second platform 46 extends along a stern direction. In other embodiments, the first axis 74 is angled or orthogonal to the center bow-stern axis 18. In other words, in other embodiments, the second platform 46 extends in a port or starboard direction, for example.

[0061] Advantageously, the sterndrive 26 can be in a raised or lowered position while the adjustable platform assembly 42 moves. In the illustrated embodiment, the sterndrive 26 is shown remaining stationary in the raised position as the adjustable platform assembly 42 moves to the first configuration, the second configuration, and the third configuration. In other words, the adjustable platform assembly 42 moves between configurations independent of the position of the sterndrive 26. Advantageously, the adjustable platform assembly 42 provides a dropped third configuration that can be enjoyed by users while the sterndrive is also raised, which is common situation for stationary use in a sandbar, for example.

[0062] With reference to FIG. 3, the adjustable platform assembly 42 further comprises a first linkage assembly 82A and a second linkage assembly 82B. In the illustrated embodiment, the second linkage assembly 82B is the same as the first linkage assembly 82A, and therefore details of the first linkage assembly 82A (also referred to herein as “the linkage assembly 82”) provided herein also apply equally to the second linkage assembly 82B.

[0063] With continued reference to FIG. 3, in the illustrated embodiment, the adjustable platform assembly 42 further comprises a first actuator 84A coupled to the first linkage assembly 82A and a second actuator 84B coupled to the second linkage assembly 82B.

As detailed further herein, the actuator 84 is configured to move the first link 96 with respect to the rail 88 and the pin 104.

[0067] In the illustrated embodiment, the pin 104 is mounted on the rail 88. In other words, the pin 104 is fixed with respect to the rail 88. The pin 104 is received within the first track 116 on the first link 96 or the second track 118 on the bracket 100. In other words, the pin 104 moves within the first track 116 and the second track 118 depending on the configuration of the adjustable platform assembly 42. In the first configuration, the pin 104 is positioned within the second track 118. In the second configuration, the pin 104 is positioned with the first portion 120 of the first track 116.

[0068] In the illustrated embodiment, the second link 108 is connected at a first end 152 to the block 92 and connected at a second end 156 to the bracket 100.

[0069] With reference to FIGS. 1A and 2A, in the first configuration, the first link 96 is positioned within a cutout 160 (FIG. 4B) formed on the block 92. In the first configuration, the block 92 is positioned at a first end 164 of the rail 88. In the first configuration, the first track 116 is aligned with the second track 118. In other words, the first portion 120 of the first track 116 is continuous with the second track 118. In the first configuration, an axis 168 of the second link 108, extending between the first end 152 and the second end 156, is parallel with the translation axis 112. In the first configuration, a bottom surface 172 of the first link 96 and a bottom surface 176 of the bracket 100 are co-planar.

[0070] With reference to FIGS. 1B and 2B, in the second configuration, the first link 96 is positioned within the cutout 160 formed on the block 92. In the second configuration, the first track 116 is aligned with the second track 118. In the second configuration, the axis 168 of the second link 108 is parallel with the translation axis 112. In the second configuration, the bottom surface 172 of the first link 96 and the bottom surface 176 of the bracket 100 are co-planar.

[0071] With reference to FIGS. 1C, 2C, and 3, in the third configuration, the first link 96 is positioned outside of the cutout 160 formed on the block 92.

[0072] Advantageously, the adjustable platform assembly 42 provides an increased useable area with room for activities and leisure. The adjustable platform 42 provides additional space for people to congregate in the second configuration, for example. The adjustable platform assembly 42 further provides means for reboarding the watercraft when in the dropped configuration, for example. Finally, unintentional contact between people outside the watercraft and the sterndrive is prevented by the adjustable platform assembly, regardless of the position of the sterndrive. In the illustrated embodiment, the first track 116 and second track 118 and corresponding pin 104 are shaped and oriented to eliminate gravity platform load influence on the actuator tension or compression.

[0073] With reference to FIG. 5, a method 200 of positioning an adjustable platform relative to a hull of a watercraft includes (STEP 201) energizing an actuator in response to receiving a first user input to extend the adjustable platform relative to the hull. The method 200 further comprises (STEP 202) energizing the actuator in response to receiving a second user input to lower the adjustable platform relative to the hull. In some embodiments, energizing the actuator in response to receiving the second user input lowers and extends the adjustable platform relative to the hull. In some embodiments, the adjustable platform is lowered into the water (e.g., positioned below the water line).

[0074] In some embodiments, the second user input is a continuation of the first user input. For example, a long press of an actuator at a user interface may transition from the first user input to the second user input. In other embodiments, the second user input is distinct from the first user input. For example, a first press of an actuator at a user interface followed by a second press of the actuator. In some embodiments, the second user input is received at the same actuator of the user interface as the first user input. In some embodiments, the second user input is received at a different actuator of the user interface as the first user input. In some embodiment, the user interface is positioned at the transom.

In some embodiments, the extension distance 70C in the third configuration is larger than the extension distance 70B in the second configuration and larger than the extension distance 70A in the first configuration. In some embodiments, a bias member (e.g., a torsion spring) is provided to assist with returning the adjustable platform assembly 42 from the third configuration to the second configuration.

[0061] Advantageously, the sterndrive 26 can be in a raised or lowered position while the adjustable platform assembly 42 moves. In the illustrated embodiment, the sterndrive 26 is shown remaining stationary in the raised position as the adjustable platform assembly 42 moves to the first configuration, the second configuration, and the third configuration. In other words, the adjustable platform assembly 42 moves between configurations independent of the position of the sterndrive 26. Advantageously, the adjustable platform assembly 42 provides a dropped third configuration that can be enjoyed by users while the sterndrive is also raised, which is common situation for stationary use in a sandbar, for example.

[0062] With reference to FIG. 3, the adjustable platform assembly 42 further comprises a first linkage assembly 82A and a second linkage assembly 82B. In the illustrated embodiment, the second linkage assembly 82B is the same as the first linkage assembly 82A, and therefore details of the first linkage assembly 82A (also referred to herein as “the linkage assembly 82”) provided herein also apply equally to the second linkage assembly 82B.

[0063] With continued reference to FIG. 3, in the illustrated embodiment, the adjustable platform assembly 42 further comprises a first actuator 84A coupled to the first linkage assembly 82A and a second actuator 84B coupled to the second linkage assembly 82B.

The first track 116 extends through the first cam end 140 and the second track 118 extends through the second cam end 144. In the illustrated embodiment, the second portion 124 of the first track 116 extends through the first cam end 140. In the illustrated embodiment, the actuator 84 is coupled to the first link 96 at a connection 148. As detailed further herein, the actuator 84 is configured to move the first link 96 with respect to the rail 88 and the pin 104.

[0067] In the illustrated embodiment, the pin 104 is mounted on the rail 88. In other words, the pin 104 is fixed with respect to the rail 88. The pin 104 is received within the first track 116 on the first link 96 or the second track 118 on the bracket 100. In other words, the pin 104 moves within the first track 116 and the second track 118 depending on the configuration of the adjustable platform assembly 42. In the first configuration, the pin 104 is positioned within the second track 118. In the second configuration, the pin 104 is positioned with the first portion 120 of the first track 116.

[0068] In the illustrated embodiment, the second link 108 is connected at a first end 152 to the block 92 and connected at a second end 156 to the bracket 100.

[0069] With reference to FIGS. 1A and 2A, in the first configuration, the first link 96 is positioned within a cutout 160 (FIG. 4B) formed on the block 92. In the first configuration, the block 92 is positioned at a first end 164 of the rail 88. In the first configuration, the first track 116 is aligned with the second track 118. In other words, the first portion 120 of the first track 116 is continuous with the second track 118. In the first configuration, an axis 168 of the second link 108, extending between the first end 152 and the second end 156, is parallel with the translation axis 112. In the first configuration, a bottom surface 172 of the first link 96 and a bottom surface 176 of the bracket 100 are co-planar.

[0070] With reference to FIGS. 1B and 2B, in the second configuration, the first link 96 is positioned within the cutout 160 formed on the block 92. In the second configuration, the first track 116 is aligned with the second track 118. In the second configuration, the axis 168 of the second link 108 is parallel with the translation axis 112. In the second configuration, the bottom surface 172 of the first link 96 and the bottom surface 176 of the bracket 100 are co-planar.

[0071] With reference to FIGS. 1C, 2C, and 3, in the third configuration, the first link 96 is positioned outside of the cutout 160 formed on the block 92. In the third configuration, the block 92 is positioned at a second end 180 of the rail 88, opposite the first end 164. In the third configuration, the first track 116 is misaligned with the second track 118.

In the third configuration, the bottom surface 172 of the first link 96 and the bottom surface 176 of the bracket 110 are misaligned and not co-planar.

[0072] Advantageously, the adjustable platform assembly 42 provides an increased useable area with room for activities and leisure. The adjustable platform 42 provides additional space for people to congregate in the second configuration, for example. The adjustable platform assembly 42 further provides means for reboarding the watercraft when in the dropped configuration, for example. Finally, unintentional contact between people outside the watercraft and the sterndrive is prevented by the adjustable platform assembly, regardless of the position of the sterndrive. In the illustrated embodiment, the first track 116 and second track 118 and corresponding pin 104 are shaped and oriented to eliminate gravity platform load influence on the actuator tension or compression.

[0073] With reference to FIG. 5, a method 200 of positioning an adjustable platform relative to a hull of a watercraft includes (STEP 201) energizing an actuator in response to receiving a first user input to extend the adjustable platform relative to the hull. The method 200 further comprises (STEP 202) energizing the actuator in response to receiving a second user input to lower the adjustable platform relative to the hull. In some embodiments, energizing the actuator in response to receiving the second user input lowers and extends the adjustable platform relative to the hull. In some embodiments, the adjustable platform is lowered into the water (e.g., positioned below the water line).

[0074] In some embodiments, the second user input is a continuation of the first user input. For example, a long press of an actuator at a user interface may transition from the first user input to the second user input. In other embodiments, the second user input is distinct from the first user input. For example, a first press of an actuator at a user interface followed by a second press of the actuator. In some embodiments, the second user input is received at the same actuator of the user interface as the first user input. In some embodiments, the second user input is received at a different actuator of the user interface as the first user input. In some embodiment, the user interface is positioned at the transom. In some embodiments, the user interface is positioned at the captain chair. In some embodiments, the user interface is a mobile device (e.g., a mobile phone, a tablet, a remote, etc.).

[0075] In some embodiments, the method 200 disclosed herein is non-transitory processor-readable medium storing code representing instructions to be executed by a processor. The instructions comprising code to cause the processor to perform the method.

[0076] In the illustrated embodiment, the watercraft 10 is a boat. In other embodiments, the watercraft is a fishing boat, a dingy boat, a deck boat, a bowrider boat, a catamaran boat, a cuddy cabin boat, a center console boat, a houseboat, a trawler boat, a cruiser boat, a game boat, a yacht, a personal watercraft boat, a water scooter, a jet-ski, a runabout boat, a jet boat, a wakeboard, a ski boat, a life boat, a pontoon boat, or any suitable motor boat, vessel, craft, or ship. Although examples are illustrated with respect to an all-electric watercraft, the methods and systems described herein can also be used in a conventional motorboat application (e.g., with a gasoline or diesel-powered engine).
