A catamaran (100) which has a center tunnel (102), the opposite sides (105a, 105b) of which form asymmetrical pontoons (106a, 106b), which are mirror images of each other, and which pontoons (106a, 106b) have buoyancy, which has been adapted so that when the catamaran (100) moves in water, the center tunnel (102) functions as a combined water and air tunnel. When the catamaran (100) is stationary in water, the ceiling (108) of the center tunnel (102) is in water. The ceiling (108) of the center tunnel further curves in a cylindrically convex manner downwards when going from the bow (116) to the direction of the stern (118) only after an essentially horizontal portion (401) of a distance (d), which essentially horizontal portion (401) is located between the pontoons (106a, 106b).
