Abstract
A sailing boat has an auxiliary hydrodynamic surface carried by a main boom connected in an oscillating way to a deck of the boat, about an axis of articulation parallel to the longitudinal direction of the boat. A drive system lowers the main boom on one side or the other of the boat in such a way that the hydrodynamic surface is selectively lowerable in a first operative position on one side of the boat to be put into the water on one side of the boat or in a second operative position on the other side of the boat to be put into the water on the other side of the boat. The boom is sized so that, when the hydrodynamic surface is located in one of its two operative positions on one side or the other of the boat, it is set at a lateral distance from the boat.
Claims18
A sailing boat provided with an auxiliary hydrodynamic surface connected to a deck and movable between a raised, inoperative, position and a lowered, operative, position, in which the auxiliary hydrodynamic surface is put into water on one side of a hull of the boat, the boat comprising:
- a hydrodynamic surface carried by a main boom pivotally connected to a deck of the boat about an axis of articulation parallel to a longitudinal direction of the boat, and
- a motorized drive system for lowering the main boom on one side or another of the boat
- in such a way that said hydrodynamic surface carried by the main boom is selectively lowerable in a first operative position on one side of the boat to be put into water on one side of the boat or in a second operative position on the other side of the boat to be put into the water on the other side of the boat,
- said main boom being sized in such a way that, when the hydrodynamic surface is located in one of the first operative position or the second operative position on one side or the other of the boat, said main boom is set at a lateral distance from the hull of the boat.
A sailing boat provided with an auxiliary hydrodynamic surface connected to a structure of the boat and movable between a raised, inoperative, position and a lowered, operative, position, in which the auxiliary hydrodynamic surface is put into water on one side of the hull of the boat, the boat comprising:
- a hydrodynamic surface carried by a main boom pivotally connected to a deck of the boat about an axis of articulation parallel to a longitudinal direction of the boat, and
- a manual drive system for lowering the main boom on one side or the other of the boat
- in such a way that said hydrodynamic surface carried by the main boom is selectively lowerable in a first operative position on one side of the boat to be put into water on one side of the boat or in a second operative position on the other side of the boat to be put into the water on the other side of the boat,
- said main boom being sized in such a way that, when the hydrodynamic surface is located in one of the first operative position or the second operative position on one side or the other of the boat, said main boom is set at a lateral distance from a hull of the boat.
