Tyvek is too air permeable for use as a sail. The function of Tyvek is
to allow air to permeate THROUGH the fabric .... and thats why its a BAD choice for sail material. Its not UV protectect and will oxidize badly and degrade in the presence of sunlight. Other than when being applied to the side of a house, when was the first time that you saw exposed Tyvek on a house .... good reason that you dont as it degrades quickly when exposed to sunlight (UV). Go to www.sailrite.com and choose a lightweight & cheap dacron sailcloth material. BTW.... they also sell sail kits .... already cut, ****properly broadseamed*** .... just assemble with two sided sailmakers seam tape, sew together on a homemakers sewing machine and sail away. Approximately 1/2 or less than a 'store bought' sail (made by indentured slave-wage workers in the orient). There are a few kit sail builders on the internet. Why go to all the work of making your own boat then hoisting poorly cut / inefficient 'crap' to move her? The sails are just as important as the care that you took when making the boat. ;-) |
