It all began with an puzzle. How do I enjoy a day on the Potomac river without shuttling cars around? Due to the strong current, it is required to put your paddle boat in upriver and then have a car or shuttle awaiting you down river. The shuttle punt solves this dilema. Bike and boat travel together, either on the bike path, or, on the river. The shuttle punt is a folding boat, a bike trailer, and a boat that can carry you and your bike. Throw in some camping gear and you have an amphibious mode of transportation for unlimited adventures.
