It functions superbly as a SUP (stand up paddleboard) and fluidly as a SOT (sit on top) kayak. Sport options range from a hardcore angler's favorite fishing vessel, to a play machine and diving platform for the whole human and canine family, to a tread mill for core training. With a spring loaded skeg system controlled with a simple lever, the Versa Board flips from agile turner in tight areas to a true tracking craft. The double tunnel design feature gives incredible stability for beginner stand up paddlers. The hidden keel adds extra strength to the board and helps with the tracking, but doesn't get caught up on shallow rocks, reefs, and sand bars because of its shallow 3" draft. The Versa board is not just an SUP or SOT it's a stable gateway to great play on lakes, rivers, and oceans. All of which you can easily get the Versa Board to using the awesome Tag Along Wheel, which comes standard with the Versa. We have developed so many accessories for the Versa board it can be whatever you want it to be-- ' la carte seating, storage, and deck-mounting options help you achieve your goal. Simply put, the Versa Board is incredibly stable, versatile and an excellent choice for beginners and experts, alike.
