Abstract
A sailboat is described having a boat hull (1), two flow profiles (2, 3) protruding laterally from the boat hull (1), and at least one underwater hydrofoil (16). To be able to achieve high travel velocities while maintaining the stability of the sailboat and balanced control behavior, it is proposed that the flow profiles (2, 3) protrude outward in a V shape from the boat hull and each have an aerodynamic stabilizer forming an aerodynamic aileron (4, 5), and/or the at least one underwater hydrofoil (16) is provided with a hydrodynamic stabilizer forming a hydrodynamic aileron.
Claims16
A sailboat comprising:
- a boat hull;
- two flow profiles protruding laterally upward and outward in a V shape from the boat hull;
- and
- a sail extending upwardly from the boat hull and in a lateral location between the flow profiles, and
- an underwater hydrofoil connected with the boat hull,
- wherein each of the flow profiles has a respective aerodynamic stabilizer forming an aerodynamic aileron configured to derive lift or downward force from air flowing thereacross, and
- wherein the underwater hydrofoil has a hydrodynamic stabilizer forming a hydrodynamic underwater aileron.
