My previous boat being double-ended, lighting board fixture was a bit tricky, solved (rather well, actually) with a bespoke boxy 'bracket' made of ply, held by slotting the vertical s/s rod which held the rudder through the bracket. Bit difficult to describe, but has worked well.
My new boat (Trouper) has the slightly curved Swallowboats transom. I assumed, perhaps naively, that gadgets to slot a lighting board onto gudgeons on a transom were 'out there'. If they are, I can't find them. Do they exist? - I can't imagine why not.
Am I missing something obvious, and/or being a bit thick? Help!
