Light-Weight Code-Zero Headsail System

View page
US Patent:
6895882, May 24, 2005
Filed:
Mar 3, 2004
Appl. No.:
10/708437
Inventors:
Joseph Dahmen - Lincoln MA, US
Clarke Bassett - Westbrook CT, US
Assignee:
Cruising Design, Inc. - Homer NY
International Classification:
B63H009/04
US Classification:
114106, 114108
Abstract:
A headsail for a sailing boat includes a luff rope having a core of parallel filaments of high-tenacity polyester and a tightly braided polyester cover, affixed in proximity to the headsail's luff. An upper marine eye is affixed to an upper end of the luff rope, while a lower marine eye affixed to a lower end of the luff rope. A length of shrink-wrap tubing is disposed about a shank of each marine eye, and is firmly shrunk about both the shank of the corresponding marine eye, and about the luff rope in proximity to the shank. A drum affixed to the lower marine eye includes a bearing assembly having an upper race, and is disposed within the drum body which contains a lower race, the bearing assembly suspended between a plurality of lower balls disposed between the upper race and the lower race, and a single upper ball. Means for restricting an excursion of the upper race relative to the lower race prevents the lower balls from distortion beyond their breaking point.

Furling Stay Cover

US Patent:
48216640, Apr 18, 1989
Filed:
Jun 12, 1987
Appl. No.:
7/062555
Inventors:
Joseph E. Dahmen - Concord MA
Assignee:
Cruising Design, Inc. - Peabody MA
International Classification:
B63H 908
US Classification:
114107
Abstract:
A forestay cover has a central tunnel for housing a forestay and two symmetrical side grooves on opposite longitudinal sides. One side groove engagably retains a staysail. The second side groove employs a hoisting handle attached to a halyard of the staysail. A cap on top of the cover provides a curved pathway for the halyard from the one side groove around one side of the central tunnel and into the second side groove. The bottom of the cover is releasably attached to a swivel which rotates the cover about the forestay and thereby furls the staysail. The cover is elastic enough to twist during furling without reaching its elastic limit. The cover is also flexible enough to bend to a radius of less than about one half its length. The swivel rotates about a bearing which is prevented from rotating by a u-shaped bracket. The legs of the u-shaped bracket are secured to the bearing and the curved portion of the u-shaped bracket is linked to a bow fixture, such as a toggle strap.
