Plan B sails are painstakingly crafted using conventional, shaped and glued seams.
The sail forms have been developed from theory, trial and observation while sailing, using a masthead video camera.
I use translucent DuPont Mylar film in both 50 and 75 micron thickness.
The available alternative, smooth finish, transparent 50 micron DuPont Mylar film is preferred by some sailors, particularly for jibs, because tell-tales are readily visible on both sides of the sail. This untreated film may be more durable.
All reinforcing patches are white for a clean appearance, but for identification you can choose from a selection of coloured jib-luff pocket tapes.
All main sails have monofilm tape reinforced luffs, further reinforced and pierced to be attached to the mast with loose ties. The mainsail is cut to stream smoothly from the lee of the mast.
The black IOM insignia is standard and you can choose, at extra charge, to have registration numbers and country designation letters clearly applied in black permanent ink, using one-time stencils.
The sails are supplied without luff wires inserted, rolled between brown paper within 90 mm. diameter cardboard shipping tubes.
