Build Fiberglass Rudder
I have on order from Stuart Marine, a Mariner 19. This is the boat previously built and marketed by O'day. Definitely looking forward to it getting here so I can put it in my slip.
Because I'll be slipping it, I think I'll be wanting to replace the stock rudder sometime in the near future. The Mariner has the typical transom hung rudder for a boat this size. Wooden tiller connected to a sandwich of aluminum plates, gripping a mahogany rudder.
I'm thinking most Mariner owners who slip their boats, remove the tiller and rudder when not in use. What I'd like to do is replace the mahogany rudder with a rudder made of fiberglass, and coat it with the prevailing anti-fouling paint here on Lake Michigan, VC17, so I can just leave it on the transom all the time.
What do you think would be the handiest/best way to duplicate the rudder in glass, or should it be thinned down where it's sandwiched between the aluminum plates, and then covered with a layer of glass and resin?
