What would you do with them?
The dimensions I mean. Having made my own I can tell you it would be very difficult with only the length and width.I took the frame and temporarily mounted it on the boat to check clearances(winches, backstay, boom, etc.) and headroom. Cut it to size with a tubing cutter. You want the side tubes to be outside the rails so that they have to be squeezed inward, provides tension. Took it home and mounted it on a 2x4 platform with strapping so all cross-bows were the same as on the boat. Then stretched sunbrella over the frame and clamped with several of those heavy-duty spring-loaded woodworking clamps, at least six on each end.Now you can use chalk to mark all the cuts and tucks, line for zippers, etc. For example, there has to be a wedge taken out of each side by the middle bow or you will have a flapping bimini.Ed(h37skipper@aol.com)
