Sails & Spars
Sail Design
We wanted a junk rig sail with camber in it for better performance than the flat sail. Aero-junk was not a consideration because of the placement of the mast and its appearance would be at odds with the rest of the design.
We chose Arne’s method because it was a proven and simple way to make camber sails.
Arne has written a complete guide for designing and building this style of sail. His excellent and comprehensive documentation is extremely helpful. These documents are regularly updated - as and when he develops new things and make ingenious improvements.
Practical Junk Rig by HG Hasler - is considered to be the 'bible' for all junk rig information. Complete guide to designing, building and sailing a Hasler style western junk rig, still in print.
Sail Making
Sailcloth: Weathermax 80.
The main reason for choosing this is because of its UV protection, guaranteed against sun damage for 10 years.
The sail is supported by many battens, it does not require the strength of the traditional sail cloth.
Arne’s comprehensive guide made it easy to make the sail, although time consuming. It took us approximately 10 days to make and 10 days to finish both sails.
