Abstract
Sailing craft having a hull, a seat disposed toward the rear of the hull and largely outboard of the hull, a mast affixed directly to the seat so that heeling forces applied to the mast are counterbalanced by the weight of a sailor primarily through the seat and not through the hull, a rotatably mounted stay extending between the top of the mast and a forward portion of the hull, a boom affixed to the stay, a sail mounted on the stay, and a rigid control rod connected to the boom for swinging the sail about the axis of the stay.
Claims25
A sailing craft comprising a longitudinally extending hull, a seat disposed toward the rear of the hull and largely outboard of the hull, a mast positioned directly above the longitudinal axis of the hull and affixed directly to the rear portion of the seat so that heeling forces applied to the mast are counterbalanced by the weight of a sailor primarily through the seat and not through the hull, a rotatably mounted stay extending between the top of the mast and a forward portion of the hull, a boom affixed to the stay, a sail mounted on the stay and attached to the boom, and a rigid control rod connected to the boom for swinging the sail, the stay and the boom as a unit about an axis extending between the top of the mast and the forward portion of the hull.
In a sailing craft:
- a single longitudinally extending hull, a seat at the rear of the hull with portions of the seat extending outboard of the hull to permit hiking out by a sailor, a mast positioned directly above the longitudinal centerline of the hull and affixed directly to the rear portion of the seat so that heeling forces applied to the mast are counterbalanced by the weight of a sailor primarily through the seat and not through the hull, and a sail attached to the mast.
In a sailing craft:
- a hull, an upstanding mast toward the rear of the hull, a downwardly and forwardly inclined stay extending between the top of the mast and the hull, pivots rotatively connecting the stay to the mast and to the hull so that the stay is free to pivot about an axis of rotation which passes through the pivots, a boom affixed to the stay, and a sail mounted on the under side of the stay and attached to the boom such that the sail, the stay and the boom are free to rotate as a unit about the axis of rotation.
In a sailing craft:
- a hull, an upstanding mast toward the rear or the hull, a downwardly and forwardly inclined stay extending between the top of the mast and the hurl, pivots rotatively connecting the stay to the mast and to the hull so that the stay is free to pivot about an axis which extends through the pivots, a boom having a pair of outwardly bowed arms affixed to the stay, a sail mounted on the under side of the stay between the arms of the boom with the luff of the sail connected to tho stay and the leech connected to the boom, and rigid control rods connected to the arms of the boom for swinging the sail around the axis.
In a sailing craft:
- a hull, an upstanding mast toward the rear of the hull, a bowed stay extending between the top of the mast and a forward portion of the hull, pivots rotatively connecting the stay to the mast and to the hull such that the stay is free to rotate about an axis passing through the pivots, a boom affixed to the stay, and a sail having its luff attached to the stay and its leech secured to the boom such that the sail, the stay and the boom are free to rotate as a unit about the axis.
In a sailing craft:
- a centrally disposed, longitudinally extending hull, a seat toward the rear of the hull with portions of the seat extending outboard of the hull to permit hiking out by a sailor, a mast positioned directly above the longitudinal centerline of the centrally disposed hull and affixed directly to a rear portion of the seat so that heeling forces applied to the mast are counterbalanced by the weight of a sailor primarily through the seat and not through the hull, and a sail attached to the mast.
A sailing craft comprising a longitudinally extending hull, a pair of outboard stabilizers positioned on opposite sides of the hull, a seat which is attached to a rear portion of the hull, a mast positioned directly above the longitudinal centerline of the hull and affixed directly to the rear portion of the seat so that heeling forces applied to the mast are counterbalanced by the weight of a sailor primarily through the seat and not through the central hull, and a sail attached to the mast.
