A note: this is just to shield us from the sun, and to act as a platform for a very lightweight solar panel. We nicknamed it 'the roll cage'(sometimes we think ourselves funny) but it is far from indestructible :>. A sturdier design would be through-bolted(pipes and deck), and its something we plan to do once we re-install a hard panel overtop, or if the boat wanders into rougher waters.
