A ship (1) provided with a bubble resistance reduction device for supplying air bubbles or a gas-liquid mixed fluid from an air bubble supply hole (10) provided to a hull (2), and leading the air bubbles to the bottom of the ship to reduce the friction resistance of the hull (2), wherein a bow bulb (3) provided to the bow of the ship is configured from a downward-flow-promoting type of bow bulb having an increased effect of leading flowing water in the bow portion to the bottom of the ship. The tip position (Pb) of a ship-bottom flat part (2f) is between X2, which is rearward from a forward perpendicular (F.P.) by at least 0.7% of a length between perpendiculars (Lpp), and X1, which is rearward by no more than 5% of the length between perpendiculars (Lpp). Air bubbles supplied from the air bubble supply hole (10) can thereby be led efficiently to the ship-bottom flat part (2f), and the air bubble supply energy for reducing the hull resistance can be reduced.
