Abstract:
1. A watercraft, comprising: a solid hull having a solid outer side and a water line, said solid outer side defining an outer surface extending at least from the water line to a top of said outer side and a concave recess in said outer surface extending substantially horizontally above the water line, and at least one undercut projection having a shape formed in said concave recess; an elastically deformable safety element having at least one concavity designed as a negative of the shape of said of least one projection such that said at least one projection engages said at least one concavity for connection of said safety element to said concave recess; and a source of pressurized fluid connected to said safety element and activatable for inflating said safety element with pressurized fluid for deploying the safety element from a first operating state, in which the safety element is folded onto itself, to a second operating state, in which the safety elements in inflated with the pressurized fluid for providing buoyancy and stability to said watercraft.
