Expandacraft is much more than a kayak! It's a modular boat system which allows you to quickly reconfigure it from one type of watercraft to another.
Buy a ready made craft or buy the hull sections separately and build your own craft.
Many kits are in development for sail, rowing, pedal power and more. Being modular, the Expandacraft will live up to its name. Constant development of new kits will help you expand your enjoyment on the water.
