Abstract An upright mast is mounted from the lateral center of the hull of a sail boat having opposite sides. The lower end of the mast is pivotally supported from the hull for angular displacement about a horizontal fore and aft extending axis adjacent the lower end of the mast and the upper end portion of the mast includes mast stay guide structure relative to which elongated flexible mast stays are guidingly engaged along their midportion for longitudinal displacement relative to the stay guide structure. One pair of corresponding ends of the stays are anchored relative to the hull opposite sides and the other pair of corresponding ends of the stays depend downwardly along the mast. Latch structure releasably anchors the other ends of the stays against upward movement along the mast and the latch structure includes high heel angle sensing release structure operative to release the other end portions of the stays for upward movement along the mast responsive to the hull experiencing a high heel angle above a predetermined maximum desired heel angle. Further, structure is connected between the hull and the mast, independent of the stays, operative to yieldingly resist angular displacement of the mast relative to the hull from a predetermined center position of the mast.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
235 words
In combination with a sail boat subject to high heel angles and including a hull having opposite sides between which the lower end portion of an upright mast is pivotally mounted for angular displacement about a fore and aft extending axis, the upper end portion of said mast including mast stay guide means relative to which elongated flexible mast stay may be guidingly engaged for longitudinal displacement relative thereto, at least one pair of elongated flexible stays, anchor means anchoring one pair of corresponding end portions of said stays relative to opposite side portions of said hull, the longitudinal midportions of said stays being guidingly engaged with said guide means and the other pair of corresponding end portions of said stays extending downwardly along said mast away from said guide means, full releasing and manually resettable latch means releasably anchoring the other set of end portions of said stays against upward movement along said mast, said latch means including high heel angle sensing release means operative to fully release the other end portion of said stays for upward movement along said mast responsive to said hull experiencing a high heel angle above a predetermined maximum desired heel angle, and angular displacement resisting means operatively connected between said hull and mast, independent of said stays, operative to yieldingly resist angular displacement of said mast relative to said hull from a predetermined center position of said mast.

In combination with a sail boat subject to high heel angles and including a hull having opposite sides between which the lower end portion of an upright mast is pivotally mounted for angular displacement about a fore and aft extending axis, the upper end portion of said mast including mast stay guide means relative to which elongated flexible mast stay may be guidingly engaged for longitudinal displacement relative thereto, at least one pair of elongated flexible stays, anchor means anchoring one pair of corresponding end portions of said stays relative to opposite side portions of said hull, the longitudinal midportions of said stays being guidingly engaged with said guide means and the other pair of corresponding end portions of said stays extending downwardly along said mast away from said guide means, full releasing and manually resettable latch means releasably anchoring the other set of end portions of said stays against upward movement along said mast, said latch means including high heel angle sensing release means operative to fully release the other end portion of said stays for upward movement along said mast responsive to said hull experiencing a high heel angle above a predetermined maximum desired heel angle, and angular displacement resisting means operatively connected between said hull and mast, independent of said stays, operative to yieldingly resist angular displacement of said mast relative to said hull from a predetermined center position of said mast.
Claim 3
Dependent Claim
35 words
The sail boat of claim 1 wherein said high heel angle sensing release means includes a weighted pendulum-type release lever pivotally supported from said mast for angular displacement about a fore and aft extending axis.
Claim 4
Dependent Claim
30 words
The sail boat of claim 1 wherein said angular displacement resisting means includes a spring means connected between said hull and mast yieldingly biasing said mast toward said center position.
Claim 5
Dependent Claim
