A ship vessel, with the vessel's length direction, breadth direction and height direction corresponding respectively to the x-axis, y-axis and z-axis of a coordinate system, wherein the x-axis and the y-axis are oriented in the horizontal plane, and the forward direction of the ship corresponds to the positive x-direction whilst the z-axis is oriented in the vertical plane, wherein said vessel comprises a foreship in front of the vessel's midship mark with a bow shape, characterized in that said bow shape is defined by a) a stem line of the foreship, which a.i) starts at the base line of the ship vessel at a first point, a.ii) then rises with an increasing curvature whilst being drawn forwards in the length direction (x-direction) to a second point slightly above the design water line and a.iii) rises further from said second point, but with a diminishing curvature and backwards (in the negative x-direction) until it reaches a third point, and b) frame lines (10, 20, 30, 40, 50) of the foreship, which b.i) are designed transversely symmetrical about the centre line of the vessel, b.ii) respectively start at fourth points (D5, D4, D3, D2, D1) on the center line, b.iii) run almost perpendicularly from the center line and increase in breadth (the y-direction) from the center line, b.iv) then respectively merge into the bilge at fifth points (G5, G4, G3, G2, G1) at a given bilge radius, b.v) from said bilge are respectively outwardly sloping up to sixth points (El, E2, E3, E4, E5), with at said sixth points (El, E2, E3, E4, E5) the outwardly sloping frame line form being terminated, and b.vi) from said sixth points (El, E2, E3, E4, E5) on are running upwards as a curved frame line form, with b.vi.1) a first set of the frame lines (10, 20, 30), arranged forward of the third point on the stem line, respectively running back to the centre line at seventh points (Fl, F2, F3) and b.vi.2) a second set of the frame lines (40, 50), arranged aft of the third point on the stem line, respectively continuing upwards with a very gentle curvature towards the centre line to seventh points (F4, F5) to design the foreship to have slender water lines. a) a stem line of the foreship, which a.i) starts at the base line of the ship vessel at a first point, a.ii) then rises with an increasing curvature whilst being drawn forwards in the length direction (x-direction) to a second point slightly above the design water line and a.iii) rises further from said second point, but with a diminishing curvature and backwards (in the negative x-direction) until it reaches a third
