Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 138 words
A device for supporting and storing the mainsail in folded condition on the boom of a sailboat, said device comprising a body portion having integral clamping means for affixing said device to said boom, said clamping means comprising an integral pair of converging jaws spaced-apart a distance smaller than the thickness of said boom and arranged to be spread apart when pressed onto said boom and to retract sufficiently around said boom when in position to securely affix said device to said boom, a pair of arms integral with and extending from said body portion, said arms being flexible upwardly and adapted to be wrapped around said folded sail, and fastening means at the ends of said arms for fastening the ends of said arms together and around said folded sail and securing said sail to said boom.
Claim 2
Independent Claim 138 words
A device for supporting and storing the mainsail in folded condition on the boom of a sailboat, said device comprising a body portion having integral clamping means for affixing said device to said boom, said clamping means comprising an integral pair of converging jaws spaced-apart a distance smaller than the thickness of said boom and arranged to be spread apart when pressed onto said boom and to retract sufficiently around said boom when in position to securely affix said device to said boom, a pair of arms integral with and extending from said body portion, said arms being flexible upwardly and adapted to be wrapped around said folded sail, and fastening means at the ends of said arms for fastening the ends of said arms together and around said folded sail and securing said sail to said boom.
