Abstract
A spar for controlling downwind headsails is pivoted to headsail instrumentalities for stowage in an aerodynamic sleeve with the headsail. The spar and the headsail has preconnected lines for controlling the spar and headsail all stored within the sleeve.
Claims10
A sailboat spar means comprising a lightweight, elongated pole having a pivot joint means, said pivot joint permitting the pole to rotate from a substantially vertical position to an operating position, said pivot joint being located at least at the pole end engaging at all times the clew of said sail means, said pole having means affixed thereto to normally maintain the pole in a vertical attitude.
The method of storing and setting a sail comprising the steps of:
- a. providing a vessel with a mast,
- b. providing a sail with a head and clew,
- c. fastening the head of the sail to the mast,
- d. providing a spar and pivoting the spar to the sail,
- e. providing means to elastically support the spar in a general vertical attitude,
- f. providing a sleeve fastened above the head of the sail and having means for raising and lowering the sleeve,
- whereby when the sleeve is raised the sail unfurls and the spar is deployed to a generally horizontal position to support the clew of the sail.
A sailboat spar means comprising a lightweight, elongated pole having a pivot joint means, said pivot joint permitting the pole to rotate from a substantially vertical position to an operating position, said pole having an end engaging the clew of said sail means, said pole having means affixed thereto to normally maintain the pole in a vertical attitude, an aerodynamic sleeve having batten pockets fastened above the head of the sail having means to lower and raise the sleeve over the sail and curved battens in said pockets to maintain an aerodynamic shape when the sleeve is lowered.
A sail system comprising a sail having at least one clew, a mast, a headstay and a spar, an aerodynamic shaped sleeve enclosing the sail, spar and headstay, said elongated spar having at least a portion thereof supported by the headstay, said spar having a pivot means and means for raising the sleeve and deploying the spar from a vertical position to a horizontal position.
A method of setting a sail for downwind comprising the steps of:
- a. providing a vessel with a mast and at least a headstay,
- b. providing a spar supported substantially parallel to the headstay,
- c. providing a sail having a head and with at least one clew,
- d. providing an aerodynamic sleeve for releasably enclosing the spar, headstay and the sail from the head to the foot,
- whereby when the sleeve is retracted, means are provided to deploy the spar to a substantially horizontal position and projecting the sail to its full span for downwind sailing and whereby when the sail is doused the spar will be returned to a generally vertical position and then the sleeve may be pulled downwardly to contain the sail and the spar.
A sail system on a vessel in combination an aerodynamic sleeve embracing a headstay, the sleeve having a plurality of spaced pockets and curved battens in said pockets, a sail adapted for stowage within the sleeve, said sail having at least a clew, an elongated spar normally supported substantially vertical whereby when the sleeve is hoisted aloft, the spar is deployed in a horizontal mode and connected to at least one clew of the sail.
