I had a 50W panel in an aluminum frame that I set on the sliding hatch when I left the boat and plugged into an outlet I put near the engine controls. Worked fine, but I got tired of carrying it and storing it below when I got to the boat. This winter I replaced it with a thin flexible 50W panel mounted on the sliding hatch with Velcro. It barely clears to slide under the traveller frame, but has so far worked fine. I coil the wires and stick them in the rope bags mounted on the front of the cockpit while sailing. Dave
