Abstract

A deck apparatus is disclosed containing interengagement means between an inflatable boat and a plurality of adjacent deck elements which are joined by a resilient link. The interengagement means prevent relative vertical movements of the adjacent deck elements and substantially all angular movement in one direction, but freely permit relative angular movement in the other direction whereby the adjacent deck elements may be folded on top of one another with the link allowing in principle, 180 degrees of relative rotation.
