my old boat is on the hard and after poking around there are some priority problems to do with the rudder. I'd really appreciate suggestions from anyone with experience of :
making a new rudder. Old grp one is splintered at bottom and cracked along seam at top. It's repairable but the internal metal straps have obviously had it. My thought is to build up a new one out of ply. What material for the new tang things and for the new shaft? Shape of rudder is very like a folkboats with a cut out for prop halfway down. This means shaft can only be bonded in at top with the tangs only strapping everything together in the upper third. Bottom of rudder swings on end of keel from a SS pivot.
My thoughts were to clad the new one in cloth and epoxy. Any advice on adhesive for laminating up the ply? I've used the polyurethane Balcotan stuff on a friends ply trailer sailor but any ideas about prolonged immersion.
