The present invention relates to the design of seagoing vessels and can be used for most hull types from slow-moving ships and barges to high-speed ships and boats that are operated up to planing speed, and also for sailing boats. The invention relates to the design of the vessel's forepart and relates to a device that reduces the vessel's wave resistance within a wide speed range, and also reduces or eliminates spray and wave-breaking resistance. The device comprises a body that is fully or partly submerged in a mass of water and positioned at the bow area, the body working in interaction with the hull behind. The body is designed and positioned such that it essentially displaces oncoming water mass in the vertical plane and then leads the water mass that passes on the top surface of the body away from and/or essentially parallel to the bow area, such the hull itself, behind the body, displaces oncoming water masses to the least possible extent. A reduced resistance to forward movement from the vessel is thus obtained. 11. A vessel () comprising{'b': 2', '3', '2', '5', '1, 'a hull () with a bow area () defined as the hull () surface area seen from in front below a water surface () when the vessel () is lying motionless and is floating in a mass of water; and'}{'b': 4', '3', '4, 'claim-text': [{'b': '41', 'a leading edge ();'}, {'b': 42', '41, 'a trailing edge () located downstream of the leading edge ();'}, {'b': '45', 'an underside (); and'}, {'b': '47', 'claim-text': {'b': 43', '41', '53', '4, "a forward top surface () that extends from the body's leading edge () to an outer contour line () of the body () seen from in front; and"}, 'a top surface () that further comprises'}, {'b': 4', '1', '1, "where the body's () highest point, seen from in front, is located higher than half the vessel's () deepest draught when the vessel (), without payload and without ballast, is lying motionless and is floating in a mass of water,"}], 'a body () arranged at the bow area () ...
