The Drifter 12 is a small trimaran that can be paddled or sailed, and is perfect for exploring rivers, bays, and lakes. The rig is simple, using a windsurfing mast. The sail rolls up and is reefable to any size in seconds. The boat is steered with rudder pedals, so your hands are always free. The amas fit inside the mail hull, making the boat very compact for storage and transport. The Drifter can be car-topped or carried on a small trailer, and it takes about 15 minutes to assemble. It is very stable and easy to sail, tacks well, and is quite fast--great for kids or anyone who is learning how to sail. The boat is easy to build out of plywood, weighing about 100 lbs when assembled.
