I have a 2000 H340 with an OEM bimini and dodger installed on the SS arch. The bimini has a small plastic window overhead so that one can theoretically monitor the set of the main sail. The window has a small Sunbrella flap on its top surface to protect it from the sun. The flap is held in place over the widow by a strip of Velcro. However, unless I am missing something, there is no way to keep the flap out of the way when sailing. The slightest breeze blows the flap back over the window and I can't see the main. I am planing to sew some Velco patches on the bimini to keep the flap open and I wonder what others may have done to remedy this situation. BTW, you have to climb way up on the arch to get to the flap.
