Nice Boat, for you Bimini, check with your Tower company, they sometimes make tops that match the tower lines exactly. I know monster does. But it saves you from attaching the top to the boat, it should attach to the tower entirely!
yep, for an example check MonsterTower web site, they probably wont work with your tower, but you should be able to source a bimini that can tie into your tower instead of your boat, makes it very nice and clean. They even make cargo bimini's, meaning you have the shade and protection of a bimini but you can also tie things on top of the bimini like wake boards, kneeboards, tubes, etc!
this is what I meant for a monster tower, im sure ur tower company makes them as well... http://shop.monstertower.com/p-103-cargo-rack-bimini.aspx
