Abstract

A water craft comprising a hull 9, a mast 1, and a pair of sail assemblies, supported by the mast and independently rotatable with respect to the vertical axis of said mast. The sail assemblies each comprise a sail, supported between two vertically spaced booms 2, screwed to swivel brackets 8, fixed to the mast. Strengthening bars 4 may be provided along the outer edge of the sail, between the two booms. The hull may be formed from a single plastic moulding, with a keel 10 screwed to the bottom.

Description

2341142 Stand up sail craft 1. Round mast ( in two sections thread on
bottom to join to keel 2. Cross members with threaded ends screw into swing brackets (see drawing 2/12) 3. Tied nylon cord to fix cross member to sail 4. One of two push on stabalising strengthening pieces 5. Screwed junction for two part mast 6. Hand grips fixed onto lower cross member 7. Cross members ( in two sections threaded to screw into lower swing bracket) 8. Swing bracket (both brackets slip over mast) 9. Standing three sided craft 10. Keel atached to craft by screw in mast and stud through base Swing bracket 1. Top swing bracket 2. Screw in cross member 3. Slide block shown with half of cross member attached 4. Slide block (as 3 above) 5. Screw junction for mast 6. Swing brackets tapered internally to fix by sliding onto tapered mast 7. Mast 8. Example of one swing bracket with both halves of cross member being attached
The idear of the stand up sail craft is to stand up and sail, by having two sails on one mast, my intention is to make from plastic, G.R.P., and carbon verying the shape of the hull and length of craft, flive to six range of craft, the craft le. drawing is to be made in plastic which is easy to put together, the main mast splits in the middle and screws together also screws into hull, each sail has a swithal block for the cross sails to screw into top and bottom of the mast, which are held by the sailor right hand left hand which controls the craft, the shape of the sail will change with the different size of craft, these are made in plastic easy to roll and carry, there is a strengthening bar for each sail to keep its shape and strength, the hulls keel is again a simple screw in by mast and through hull the key to this craft is the twin sails with swithal blokes.
Amendments to the claims have been filed as follows The idear of the stand up sail craft is literily to stand and sail by having two swithal sails on one mast, my intention is to make from plastic through G.R.P. and carbon verying the shape of the hull as the price range changes, the craft le drawings 1 and 2 is plastic which is easy to put together and screws into hull each sail has a swithal block for the cross sails to screw into top and bottom of the mast which are hand held the shape of the sails will change with the size of the craft these ones are made of plastic easy to roll and store away to keep the sails shape there is a strengthening bar on each side the hull is a one piece and the keel screws into the hull
