I'd look at putting in some form of hanging system that kept your gear close to the roof.
I had a setup with a fixed loop for the nose of the board, and a pulley arrangement for the tail so that you poke the nose through the front loop, push the back of the board through the loop, then pull the string and the board gets elevated to the roof. If you then organise a cuphook for the bit of string you used to pull the board up with, then everything stays neat and out of the way.
Only problem is you'll have to drill a couple of holes with a masonry bit, and I purposely haven't talked about the sails 'cos that problem's too hard for me
