Abstract
A surface effect vessel of a type comprising a buoyed structure with two side keels (20), a rear seal apparatus (100) and a forward seal apparatus cooperating to delimit a central buoyancy cushion (300). The rear seal contains a horizontal extension enclosure (100). A first piping system (54) connects a pressurized air generator (50) to the enclosure (100), and a second piping system (58) connects the central cushion (300) and the pressurized air generator (50). Fluid communication holes (150) are provided between the enclosure (100) and central cushion (300). The piping system (54, 58) and the fluid communication holes (150) are defined to ensure inflation of enclosure (100) to a pressure higher than the pressure of the central cushion (300).
