I'm considering buying a used bimini and mounting it on my Hunter 23.5. It looks like biminis that are made for the 23.5 mount on the top of the side walls (combing?). Can anyone tell me the hight of the bimini when it is up? I am considering getting one that I could mount on the hull to topside flang joint similarly to the way the side stays are anchored (just above the rub rail). This looks like it would be easier and a stronger mounting point. Are there any problems with this? Would I need to seal the holes to make sure water doesn't get in? Thanks.
