Abstract: A device for releasably connecting a rigid deck and a rigid hull to the covers of the bladders of an inflatable boat comprises an assemblage of two rigid plates joined together along their edges to form a sealed chamber which is fastened to the covers of the bladders, or directly to these latter, through bolts acting through the intermediary of suitable pressure elements. Holes passing through the edges of the two rigid plates are provided for the bolts.

Abstract: An inflatable boat has a pair of elongated inflatable side portions extending lengthwise of the boat, disposed within an envelope that can be opened and closed by longitudinally-extending openings on its outer side, to permit insertion and removal of inflatable chambers. The margins of the envelope openings are maintained closed by interfitting loops, each loop receiving a slotted pin with the head and tail of the pin projecting from opposite sides of the loop, so that the pins of the loops associated with one margin of the opening interfere with the heads and tails of the pins projecting from the loops associated with the other margin of the opening, thereby to hold the margins together. A rigid panel at the stern of the boat supports an outboard motor, and is detachably secured between the side members by special screw assemblies. At the prow of the boat, relatively vertically swingable panels provide a deck in one position and the support for a short ladder in another position.
