Abstract
Abstract A mast is equipped with a series of attachment devices for permitting the sail to move to the leeward side of the mast as the direction of the wind relative to the mast changes. The mast includes an elongated body having a generally A-shaped cross section which includes a forward edge and a pair of diverging sides. An extended clip or a series of wire loops attach the sail to the mast and extend along the aft portion of the body, and a series of rod like structures extend laterally from one side of the body to the other to permit the luff attaching devices to move to the leeward side of the body.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
124 words
A mast comprising an elongated body having a top and a bottom and a forward portion and an aft portion, a pair of sides extending rearwardly from the forward portion, and sail-attaching means extending longitudinally adjacent the aft portion of the body and attached thereto for attaching a sail to the mast, the sail-attaching means including luff-attaching means for holding the luff of a sail and slide means extending transversely across the aft portion of the mast for slidably supporting the luffattaching means for lateral movement said luff attaching means whereby the luff-attaching means and the luff can move laterally from one side of the mast to the other on the slide means as the direction of the wind relative to the mast changes.
Claim 2
Dependent Claim
124 words
A mast comprising an elongated body having a top and a bottom and a forward portion and an aft portion, a pair of sides extending rearwardly from the forward portion, and sail-attaching means extending longitudinally adjacent the aft portion of the body and attached thereto for attaching a sail to the mast, the sail-attaching means including luff-attaching means for holding the luff of a sail and slide means extending transversely across the aft portion of the mast for slidably supporting the luffattaching means for lateral movement said luff attaching means whereby the luff-attaching means and the luff can move laterally from one side of the mast to the other on the slide means as the direction of the wind relative to the mast changes.
Claim 3
Dependent Claim
29 words
The structure of claim 1 in which the slide means includes a plurality of longitudinally spaced rods which extend transversely between the sides of the body of the mast.
Claim 4
Dependent Claim
25 words
The structure of claim 2 in which each rod is secured to the body of the mast at a fixed position along the length thereof.
Claim 5
Dependent Claim
15 words
The structure of claim 3 in which the luff-attaching means is formed of extruded plastic.
Claim 6
Dependent Claim
18 words
The structure of claim 3 in which each of the rods extends through the side of the body.
Claim 7
Dependent Claim
52 words
The structure of claim 2 in which the luff-attaching means includes an elongated attaching portion through which the rods extend, the attaching portion being engageable with each side of the mast body when the sail moves to that side to substantially close any air gap between the sail-attaching means and the mast.
Claim 8
Dependent Claim
25 words
The structure of claim 1 in which the luff-attaching means is provided with a longitudinally extending groove for slidably receiving the luff of the sail.
Claim 9
Dependent Claim
74 words
The structure of claim 1 in which the aft portion of the body includes a rear wall extending between the sides of the mast and longitudinally extending track means mounted on the rear wall, the sail-attaching means comprising a plurality of slides slidably mounted on the track means for longitudinal movement therealong, the slide means comprising a tranversely extending rod secured to each slide and extending laterally between the sides of the mast body.
Claim 10
Dependent Claim
137 words
In combination, an elongated mast and a sail having a luff, the sail being slidably attached to the mast for transverse sliding movement, the mast having a top and a bottom and a forward portion and an aft portion, a pair of sides extending rearwardly from the forward portion, a plurality of longitudinally spaced rods extending transversely between the sides, and elongated luff-attaching means for holding the luff of the sail, the luff-attaching means being slidably mounted to the rods for transverse movement between the sides of the mast and being provided with a longitudinally extending groove which receives the luff of the sail whereby the luff-attaching means and the luff can move laterally from one side of the mast to the other on the rod as the direction of the wind relative to the mast changes.
Claim 11
Dependent Claim
137 words
In combination, an elongated mast and a sail having a luff, the sail being slidably attached to the mast for transverse sliding movement, the mast having a top and a bottom and a forward portion and an aft portion, a pair of sides extending rearwardly from the forward portion, a plurality of longitudinally spaced rods extending transversely between the sides, and elongated luff-attaching means for holding the luff of the sail, the luff-attaching means being slidably mounted to the rods for transverse movement between the sides of the mast and being provided with a longitudinally extending groove which receives the luff of the sail whereby the luff-attaching means and the luff can move laterally from one side of the mast to the other on the rod as the direction of the wind relative to the mast changes.
Claim 12
Dependent Claim
52 words
The structure of claim 9 in which the luff-attaching means includes an elongated attaching portion through which the rods extend, the attaching portion baing engageable with each side of the mast body when the sail moves to that side to substantially close any air gap between the luff-attaching means and the mast.
