CONSTRUCTING A SPINNAKER FROM POLYTARP

 

Spinnakers are best made from a lighter weight polytarp, such as the common 6 x 8 weave, 2.5 0z. blue polytarp found at hardware and home improvement stores. Look for a colorful, light tarp that will complement your boat. Next, run double-faced tape around the outline of your sail, making certain that you leave enough material to overlap at the center line. No reinforcing line is needed in the overlaps, but you will need to sew up the center of your sail. With the addition of a couple of strategically-placed V-Darts and three grommets, one at each corner, you should be able to finish construction of a spinnaker in a couple of hours.
