Benefits of technology

[0012] Particularly preferably the board is assembled of one or more major longitudinal sections that are coupled together in use. Decoupling of the longitudinal sections enables the board to be stowed in a much more compact state for storage or travel. For example, by forming the board in two sections of substantially equal length, a fore portion and an aft portion, these may be stacked one on top of another to occupy a space half the length of the assembled board. The releasable coupling of the longitudinal sections of the board may comprise a pin-in-slot coupling.
[0013] In a further refinement, the board may be coupled to one or more lateral board sections to provide a side stabilisation effect in the manner of a catamaran or similar. Lateral releasable coupling of board sections may also be used as a means for providing tandem configurations of board for two or more users to work together. Thus, for example, paired coupled boards may be used for training purposes or for two or more people to share propulsion of the assembled boards. Laterally coupled sections / boards may be releasably coupled in a pin-in-slot manner as per the longitudinal section couplings.

Problems solved by technology

Given that these sports require a level of fitness and skill they are not ideally suited to all, but their appeal is widespread.

first embodiment

[0068] Turning now to the viewing port 10′, this differs from the viewing port of the first embodiment by having a raised cowl 60 formed as an integral part of the moulding of the board 1′ and which has a rectangular shape in plan but in profile is inclined downwardly in the aft direction of the board. The viewing port 10′ is configured as a viewing turret and as viewed in plan from above as in FIG. 6 the sides of the cowl 60 all taper downwardly. Furthermore, as viewed from the underside as in FIG. 7, it will be seen that the viewing port 10′ underside substantially conforms to the tapering cowl walls 60 of the top surface and thus has a relatively broad aperture area at the base compared to the upper aperture area of the viewing port 10′. In this embodiment, the viewing port 10′ has two glazing panels—one 11a′ sits at the top of the viewing port 10′ turret spanning the aperture of the viewing port 10′ and the other of which 10b′ is mounted to the base of the viewing port spanning ...

third embodiment

[0074] As can best be seen with respect to the invention shown in FIG. 13, the board aft section 1b′ is suitably provided with an enhanced drainage arrangement at the footwells 65 by provision of drainage flutes / channels 67 running along a lateral edge of each footwell 65 and inclined at a slope that is illustrated as being from front to rear and where at the rear end of each channel 67 there is a drainage hole 68 through the board to allow any water entering the footwells to be discharged through the bottom of the board (see FIGS. 15 and 17).

second embodiment

[0075] The third illustrated embodiment of the invention, illustrated in FIGS. 13 to 18, technically differs most notably from the second embodiment by, in addition to the drainage channels 67 in the footwells 65 at the rear of the board, having mounts 69 for a canopy. Whereas the propellers here have three vanes, the craft suitably has at least three vanes on each propeller and preferably four or more.

[0076] Canopy 70 is illustrated in FIGS. 16 and 17 as held on a support structure above the prone user on the board. The support structure here comprises a leg structure 71, 72 on each side of the canopy to couple to the corresponding side rail of the board 1′. Each leg structure comprises a pair of legs 71a,b: 72a,b hinged together at mid height to be collapsible in a scissor action for storage, each leg being hingedly mounted to the canopy at its upper end for this purpose. The lower end of each leg has an inwardly angled portion to push-fit into a corresponding socket 69 in the cor...

Abstract

The present invention provides a water-borne craft comprising a flotation board for personal use (e.g. one or two man use) wherein the board has towards its leading edge/nose a portal formed in the board through which a user lying prone on the board may view underwater, the board being further provided with paddle means for propulsion of the board by a user while lying face down/prone on the board.

Description

FIELD OF THE INVENTION [0001] The present invention concerns water-borne craft and in particular concerns personal craft of the floating board type such as surf / body boards or which are otherwise known as water-sports boards. BACKGROUND TO THE INVENTION [0002] When holidaying at sheltered beach resorts around calm, clear-watered areas, leisurely water based pursuits such as snorkelling are particularly popular pastimes. By contrast, in more turbulent coastal areas with strong winds and waves, water-sports such as wind-surfing, kite-surfing, surf boarding or body / boogie boarding are, appropriately, more popular. [0003] Surf boarding and body boarding are active sports that exploit hydrodynamic features of specially streamlined full body length, finned or shortened, finless flotation boards, respectively, to enable a user to ride incoming waves. In the more basic form of the body / boogie board, the finless shortened-length flotation board initially supports the upper body of a swimmer ...
