Check out a triangular sun shade for foredeck
Hey, Rick-Not everything useful on a boat necessarily comes from a marine specialty shop or a W/M catalog. Check this link from, of all places, Hammacher Schlemmer (800-543-3366) - but I've seen it in other catalogs, too. The triangular Down Under Sun Shade comes in either green or sand and in two sizes: 16' 6" on a side ($89.95) and 11' 10" ($74.95, listed in the Father's Day mail catalog, but not on the website). The smaller size should approximate your C-36 J-dimension. Best, air circulates through it. While the corners have re-inforced D-rings, an additional D-ring would have to be sewn in half-way along one side to which a halyard could be attached, providing a bit of a peak at the mast and adjusting the aft side to the beam. I suspect that the cost is but a mere fraction of some custom canvas work and could even function better.Ernie April
