Abstract
Abstract A sailboat having a plurality of triangular sails each provided with an integrated sail cover in the form of two elongated strips of weather-resistant cover material attached to the foot and the leech of the sail to overlie the exposed portions thereof between successive convolutions of the associated edges when the sail is furled in a conventional manner on a rotatable supporting element such as a luff wire extending along and secured to one edge thereof.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
120 words
In combination with a sail having one side edge connectable to an elongated rotatable supporting element and two additional side edges disposed at acute angles relative to said one side edge to be wrapped helically around said supporting element as the latter is rotated to furl said sail thereon, a sail cover comprising two elongated strips of sail cover material disposed on the same side of said sail and overlying the side edge portions of said sail along said two additional edges, said strips being fastened to said side edge portions and being at least as wide as the spacing of successive convolutions of the associated edge, thereby to cover said sail when the latter is furled on said element.
Claim 2
Dependent Claim
120 words
In combination with a sail having one side edge connectable to an elongated rotatable supporting element and two additional side edges disposed at acute angles relative to said one side edge to be wrapped helically around said supporting element as the latter is rotated to furl said sail thereon, a sail cover comprising two elongated strips of sail cover material disposed on the same side of said sail and overlying the side edge portions of said sail along said two additional edges, said strips being fastened to said side edge portions and being at least as wide as the spacing of successive convolutions of the associated edge, thereby to cover said sail when the latter is furled on said element.
Claim 3
Dependent Claim
59 words
The combination defined in claim 1 in which said one side edge is the luff of said sail and said additional side edges are the foot and the leech, said strips extending along the full lengths of said foot and said leech and being wider than the spacing of said successive convolutions to overlap when the sail is furled.
Claim 4
Dependent Claim
27 words
The combination defined in claim 2 in which said strips are disposed entirely on said same side and have edges substantially flush with the associated sail edges.
Claim 5
Dependent Claim
39 words
The combination defined in claim 2 in which said strips have U-shaped bends extending around said associated sail edges and lapped edge portions overlying part of the other side of the sail for complete protection of said sail edges.
Claim 6
Dependent Claim
20 words
The combination defined in claim 1 in which said strips are on the order of 8 to 15 inches wide.
Claim 7
Dependent Claim
22 words
The combination defined in claim 1 in which said strips are composed of substantially heavier material than the material of said sail.
Claim 8
Dependent Claim
111 words
In combination with a sail having a first side edge connectable to an elongated rotatable supporting element and at least one additional side edge disposed at an acute angle with said first side edge to be wrapped helically around said supporting element as the sail is furled thereon, a sail cover comprising an elongated strip of sail cover material disposed on one side of said sail and overlying a preselected width of the edge portion of said sail along said additional side, said strip being secured to said sail and said preselected width being correlated with said angLe to cover the exposed portion of said sail when the latter is furled.
Claim 9
Dependent Claim
111 words
In combination with a sail having a first side edge connectable to an elongated rotatable supporting element and at least one additional side edge disposed at an acute angle with said first side edge to be wrapped helically around said supporting element as the sail is furled thereon, a sail cover comprising an elongated strip of sail cover material disposed on one side of said sail and overlying a preselected width of the edge portion of said sail along said additional side, said strip being secured to said sail and said preselected width being correlated with said angLe to cover the exposed portion of said sail when the latter is furled.
Claim 10
Dependent Claim
40 words
The combination defined in claim 7 in which said strip is wider than the normal spacing between adjacent convolutions of said edge when said sail is furled about said first side, whereby successive convolutions of said strip overlap each other.
Claim 11
Dependent Claim
115 words
The combination defined in claim 7 in which said sail is triangular and has two of said additional side edges forming a leech and a foot, said first side edge being a luff connectable to a luff wire, and in which said sail cover comprises two elongated strips of said sail cover material extending along said leech and said foot on the same side of said sail and each being slightly wider than the normal spacing between adjacent convolutions of the associated edge when said sail is furled about said luff, whereby said strips are coiled helically about the luff with successive convolutions of each strip in overlapping relation to completely cover the furled sail.
Claim 12
Dependent Claim
17 words
The combination defined in claim 7 in which said strip is between 8 and 15 inches wide.
Claim 13
Dependent Claim
39 words
The combination defined in claim 7 in which said strip has a U-shaped bend around said additional side edge and a narrower lapped edge portion secured to the other side of said sail to protect said additional side edge.
