The present invention includes a trailer (1) adapted for a boat (B), having a chassis (2) shaped like a "U", provided with wheels and having a number of struts (10, 11; 12, 14) supported by the chassis and slings (16) or the like oriented between struts (10, 11) coordinated in pairs, which slings are intended to support said boat by directly or indirectly abutting against an outer surface of a hull belonging to the boat, said chassis (2) being formed by two flexurally rigid branches (21, 22), each one turnably related and connected with a connecting part (23) of a first end portion (22a) of the respective branch, and where at least selected struts (10, 11) consist of one hydraulically operating piston-cylinder arrangement (10a) each. Said piston-cylinder arrangements are hydraulically directly interconnected with each other and that this interconnection (61, 62) then is adapted to let hydraulic oil be distributed under an overpressure between the same arrangements (10a, 11a), in dependence of the rocking or rolling motion of the hull of the boat (B), preferably emanating from the twisting motion of the branches (21, 22) in relation to the ground (M) and the twisting motion thereof in relation to said connecting part (23).
