I have a 21' Seadoo Challenger and need a bimini top (of course I've checked all the ones offered at iboats and have one in mind as well). I found another site that has a 7' long bimini top which I think would be perfect. I would like a little longer than 6' but though 8' might look to big for the boat. My concern is that this company only makes the bimini tops 52" tall, no shorter. My gunnels are about 3' tall so we're looking at a total height of about 7'4". What are your thoughts on this height? Ideally I wanted a 46" tall bimini. Also, the companies website (northstarproductsinc.com) keeps referencing pontoon boats but they say it will fit any boat. Sound right? Thanks in advance for your replies...
