Abstract:
1. A pneumatic boat including two inflatable buoyancy chambers extending at least on either side and kept spaced apart by a rigid bottom and by a transom, at least one stabilizing flap being secured to the base of the transom so as to extend rearwards beyond said transom, wherein the flap is fixed to the base of the transom by fixing means capable of allowing the flap to occupy, selectively, a functional position and a nonfunctional position, wherein the flap comprises: a principal flap board, which is rotatively supported by first rotation means on a base plate secured on said transom, and a lateral flap wing, which is secured to said principal flap board on that side thereof which faces the corresponding chamber by means of second rotation means approximately transverse to said first rotation means and allows folding of said lateral flap wing against the lower face of the principal flap board in said nonfunctional position and the deployed positioning of said lateral flap wing substantially in the extension of said principal flap board, said lateral flap wing being dimensioned and shaped such that, in said functional position, a lateral edge of said flap wing is engaged under the corresponding inflatable chamber and simply bears freely, vertically upwards, against said chamber, and wherein first and second immobilizing means are associated functionally with said first and second articulation means so as to lock said principal flap board and lateral flap wing in their respective positions corresponding to the functional position of the flap.
