Finally, I installed a window in the bimini so that we can see the main sail. I also made a cover for the window that attaches with Velcro on all four sides. George had the brilliant idea to add 2 short pieces of Velcro on the other side of the cover so that it can also be rolled up. The window had to be located in the center because of the solar panels. It is not ideal, but it is better than nothing!
