Thanks for everybodys help over at the battery thread.What I'm up to now is making something like a 'suntarp' to cover all the area between the bow and the front of the mast (on a Hunter 27). When installed it'll secure to the safety cable and will form a parallel plane with the water...so it's going to look like an 8ft tall triangle that's about 6ft wide at the bottom. The base of this triangle tarp will be attached to the mast and pulled vertically lower to allow for rain runoff. I've gotten as far as making a template of the boat's safety lines and mast...it's on my floor now.So my questions concerns how I should go about making attachments for this thing to secure it to the safety lines. I'd like for it to extend all the way to the lines, but some of attachment ideas I've had call for leaving the tarp 3-4 inches short.Anybody have ideas on what kind of attachment mechanism I should use? Ideally they should be sewn into the tarp itself so they don't get lost. Also, seems like some elasticity should be built into them to keep things steady in the wind. Best idea so far is to use some kind of industrial elastic to attch 'dog collar' hooks to the underneath side about 8-10 inches from the edge, stretched they'll serve to hold the tarp tight; as well as hooks directly on the edges to keep them from flapping.Thanks for your ideas
