Modular kayak with elevated hull voids

A sit-on-top kayak hull with elevated voids comprising:

• a hollow hull integrally formed as a single unitary member defining a surrounding hull and interior void, the surrounding hull having a bow end and a stern end longitudinally spaced from the bow end and a port side and a starboard side laterally spaced from the port side and a top surface and a bottom surface vertically spaced from the top surface and primary interior walls extending from said bottom surface to said top surface and longitudinally spaced from said bow end, and longitudinally spaced from said stern end and laterally spaced from said port side and laterally spaced from said starboard side, the interior void being an embrasure open on the top and open on the bottom and vertically surrounded by said primary interior walls,
• a cockpit defining a seating surface and port and starboard leg recesses, the seating surface being a depression within said surrounding hull top surface of sufficient depth to be below the top of said primary interior walls and above the normally laden waterline and located aft of said interior void, and laterally centered within said surrounding hull top surface, the port and starboard leg recesses being depressions within said surrounding hull top surface of sufficient depth to be below the top of said primary interior walls and above the normally laden waterline and arranged transversely straddling said interior void and adjacently forward of said seating surface,
• a cockpit drainage system defining interior wall drain recesses and cockpit drains, the interior wall drain recesses defined as depressions traversing upwardly within said interior walls, the cockpit drains being a bore of sufficient size to allow water drainage from within said cockpit and traversing through said top surface and through said primary interior walls into said interior void,
• attachment means for releasably attaching items of a size and shape to fit within said interior void,
• a bracing system wherein said cockpit seating surface and port and starboard leg recesses are of sufficient depth to define the interior void as elevated to a height to be used a brace member, whereby the operator maintains control of the watercraft by gripping the brace member between an inner side portion of each of the operator's legs.
