This invention concerns a surface effect vessel whose type comprises a buoyed up structure fitted with two side keels (20), an rear seal apparatus rear and a forward seal apparatus (200) both delimiting a central buoyancy cushion (300). According to the invention the forward seal apparatus (200) consists of an upper horizontal extension shell (210) extending between the two side keels (20) which communicates with the central cushion (300) so as to be supplied by it and two rows of lower multilobe skirts (230, 250) connected below the upper shell (210), which converge towards the center of the central cushion (300) from top to bottom, and whose concavity faces the center of the central cushion (300), the multilobe skirts (230, 250) together delimiting the intermediate chambers (254) which communicate with the upper shell (210) via ports provided in its wall.
