Inflatable boats with rigid flooring

Rigid plywood flooring

— the covering in the form of a rigid surface is sometimes continuous, but more often in the form of 3-4 segments connected closely by flexible fasteners (this design allows the flooring to be folded when being carried). Rigid flooring is simple, reliable and inexpensive, due to which it has become widespread in boats with inflatable keels; but for classic flat bottoms, they are almost never used for a number of reasons.
