Here you go
The previous owner designed one for my 23.5, it works pretty good except for in the rain. I just modified it this weekend and now the rain doesnt collect in it.Here is the basics of the cover: I will have to get the exact measurements at a later time.> the length of the cover is from the mast running the length of the boom.> the width is from life line to life line across.> the support is a 1X2 board running through the forward, middle, and rear sections of the material (there was a slot for the boards sewn in)> On the ends of the boards are small eye bolts facing down to attach bungee cords from the boards to the life line supports.As i said earlier, the cover works well for shade but collects rain. So what i did this weekend is flip the center support board so the eye bolts are facing up and i attached a nylon line from eye bolt to eye bolt and connected the main halyard and added lift to the center. Now it works well. I hope this makes sense to you... i will post some pictures soon so you can take a look.Good luckGreg s/v Passin Wind
