Thanks... it's actually a Bravura (only 21') but anyway, same lines.
The low height was key to get the most shade possible. The tower curves in so much, if it was up high it would have been useless at all times other than high noon in July (I also would have had to go with a smaller width bimini). You cannot stand up under it, needless to say. But it's just right for sitting on the gunwale - my head is above it so I can see over it. Someone sitting on the engine can also see over it.
It's not bad to get under, and it provides fabulous shade for the kids when we only go out for an hour or two... which was the goal. Not having to sunscreen two small children for a short boat ride is a game-changer.
I spent a LOT of time measuring before assembling that whole setup. It was time well spent.
