Abstract
A sailing craft of the type which includes a floating hull, a mast secured to the hull, a sail mounted on the mast and rudder means, wherein the mast is pivotally mounted with an articulation near but spaced from the base thereof with respect to a substantially horizontal axis, and a pair of mobile fins having variable lift movably mounted, each on a respective one of the port and starboard sides of the hull, and a linkage interconnecting the mast and the mobile fins for actuating the fins such that they act in the water in a manner so as to tend to right the hull under the dynamic action of water on the fins in a direction opposite to the direction in which the mast pivots, and in which the craft would normally heel under the action of the wind to which it is exposed.
Claims11
Sailing craft of the type including a floating hull, a mast secured on the hull, a sail mounted on the mast, and a rudder means, comprising:
- said mast being pivotally mounted with an articulation near but spaced from its base with respect to a substantially horizontal axis wherein when the mast pivotally oscillates around its axis of articulation, the base of the mast moves substantially transversely from port to starboard, a pair of mobile fins having variable lift movably mounted, each on a respective one of the port and starboard sides of the hull, and means interconnecting said mast and the mobile fins for actuation of the mobile fins, such that the fins act in the water in such a way as to tend under dynamic action of water on the fins to right the hull in a direction opposite to the direction in which the mast pivots, and in which the craft would normally heel under the action of just the wind to which it is exposed, said actuation means comprising a transverse bar in which the base of the mast is entrained, at each end of which there is articulated one end of a connecting rod, whereof the end of the connecting rod opposite the articulation on the said transverse bar is integral with a substantially vertical pivot articulated in a structural element fixed to the hull and around which one said fin, on the port or starboard side, respectively, can rotate.
Sailing craft of the type including a floating hull, a mast secured on the hull, a sail mounted on the mast, and a rudder means, comprising:
- said sail comprises two substantially symmetrical, triangular parts fixed to said mast with a sheet for holding each sail, attached to the lower free end of the sail not fixed to the mast, each sheet passing over a pulley fixed at the end of an arm that can be oriented to port or to starboard, said mast being pivotally mounted with an articulation near but spaced from its base with respect to a substantially horizontal axis, a pair of mobile fins having variable lift movably mounted, each on a respective one of the port and starboard sides of the hull, and means interconnecting said mast and the mobile fins for actuation of the mobile fins such that the fins act in the water in such a way as to tend under dynamic action of water on the fins to right the hull in a direction opposite to the direction in which the mast pivots, and in which the craft would normally heel under the action of just the wind to which it is exposed.
Sailing craft of the type including a floating hull, a mast secured on the hull, a sail mounted on the mast, and a rudder means, comprising:
- said mast being pivotally mounted with an articulation near but spaced from its base with respect to a substantially horizontal axis, a pair of mobile fins having variable lift movably mounted, each on a respective one of the port and starboard sides of the hull, and means interconnecting said mast and the mobile fins for actuation of the mobile fins such that the fins act in the water in such a way as to tend under dynamic action of water on the fins to right the hull in a direction opposite to the direction in which the mast pivots, and in which the craft would normally heel under the action of just the wind to which it is exposed, and further including a lever articulated around a horizontal axis in the median longitudinal plane of the craft and toward its stern part, and which can rotate on itself, the said lever terminating at its upper end above the hull in an operating handle, and at its lower end, below the hull, in a plane in the general shape of a dolphin's tail.
