A fore body (1) of a ship, comprising a bow having an upper bow portion (30), a lower bow portion (10) and an intermediate recessed bow portion (20). The recessed bow portion (20) comprises a blunt shaped surface (23), curving inwards and backwards from a transition area (p4) between the upper bow portion and the recessed bow portion (20), said blunt shaped surface (23) being designed to reflect smaller waves and thus reduce the added wave resistance in smaller waves which are reflected in the recessed bow portion (20), whereby the energy of the wave is treated in a relative short period of time and the tendency for the small waves to follow the hull shape further aft is generally prevented.

La présente invention se rapporte à une coque avant (1) d'un bateau, comprenant une proue comportant une partie proue supérieure (30), une partie proue inférieure (10) et une partie proue intermédiaire renfoncée (20). La partie proue renfoncée (20) comprend une surface de forme émoussée (23), s'incurvant vers l'intérieur et vers l'arrière depuis une zone de transition (p4) entre la partie proue supérieure et la partie proue renfoncée (20), ladite surface de forme émoussée (23) étant conçue pour renvoyer de plus petites vagues et ainsi réduire la résistance aux vagues ajoutées dans les plus petites vagues qui sont renvoyées dans la partie proue renfoncée (20), l'énergie de la vague étant traitée en une durée relativement courte et la tendance des petites vagues à suivre la forme de la coque plus vers l'arrière étant globalement évitée.
