I believe I get too much wind for shades or panels, but if shades like these are on tracks and when up can be protected from the wind... I would want them on the walk out level. Having a way to create shade on hot or especially bright parts of the day would be nice. Sometimes the sun reflects off the water and it's blinding.
small part of the picture - but a place to hang and store towels. Towels end up thrown over my upper patio railing and I would prefer to have the walk out level designed better for in and out to the lake. Towels, ice machine (for drinks), hooks for boat keys and boat stuff. Dock cleats would make great towel hooks.
