Title:
CANOE
Document Type and Number:
WIPO Patent Application WO/2020/085287
Kind Code:
A1
Abstract:
The present invention improves the straight traveling performance and acceleration performance of a canoe. A canoe 1 includes a hull 2 including a ship bottom 2a and ship sides 2b, and a deck 3 covering the hull 2. The ship bottom 2a is formed to have an airfoil-shaped profile in a horizontal plane, such as a first curve c1, a second curve c2, and a third curve c3, and in a vertical plane parallel to the center line C-C of the ship bottom 2a. This airfoil shape improves the straight traveling performance when the canoe moves forward with respect to the water, and also improves the forward acceleration performance when the canoe moves backward with respect to the water.
