Starboard, unless really thick (but then is heavy & expen$ive), actually bends way too much for my taste. I prefer plywood wetted out with epoxy and then painted.
It’s also sooooo slick that I saw an small OB pop off a transom once & sink in 20+’ of water, when a guy in a big boat, towing his dinghy w/ that OB on it, ran over a mooring ball that hooked the dinghy OB’s prop & POOF - gone!
