bimini height
Gary,You are correct, the boom will come very low for a normal bimini. I own a 85 hunter 31 and there are 4 others at our club. Three of us have made custom biminis for our boats and they mount on the stern life line rail and go forward to the companion way. Section one covers from the stern to just rear of the boom and can be kept up.Section two zips onto this and will cover forward to the companion way bulkhead and zips on a frame mounted to the cabin roof. This is slightly lower but works quite well. With the companion way slide closed you should get no rain in the boat with the forward bimini section installed. We did have to alter the foot of the sail to accomplish this though, but with no noticeable effect on sail performance. We cut approximately an 8" to 12"section from the rear leach at the clew and feathered it to the luff. I bent the frames from 1" stainless tubing I purchased at a mill supply. It was 10 gauge polished tubing used in hospitals. I used a normal conduit bender but had to modify it to to keep from kinking the tubing. I will be glad to send pictures and measurements if you like. E-mail greghatcher@comcast.net. Hope this was some helpGreg
