Unlimited is not really a "class" like all the others. Rather, it consists of all those boats which, for one reason or another, (number of paddlers, double blades, or rudders) do not fit into any of the actual classes. All entrants compete for overall position, but when you enter Unlimited, that is ALL you compete for.

Boat Specifications

There shall be no specification as to the type or size of craft used except that such craft must be propelled only by human muscle power and there can be no more than six persons present in the craft and is limited to a maximum of six persons.)
