I just put a bimini on my 23.5 that I ordered from Ameriseam. You can order direct from them or order from this site (they make the one sold here). Same price either way. The bimini from Ameriseam is made to fit a couple inches below the boom when close hauled, so there should be no interference. You do have to move the boom out of the way sideways to fold it or unfold it, but that's a very minor inconvenience. FWIW, one other modification we did to our boat that I highly recommend is installing a "boomkicker". It does away with the topping lift, makes reefing a breeze, and gives you better sail shape in light wind.
