    Any suggestions for the correct support for these mufflers? I hate the sloppy wood...

    Maybe something like this bolted to the stringer with an aluminum or stainless bracket?

    • Why not copy the wood brks. using stainless, It would sure look great.

      • The wood has some give that probably needs to stay available. A stainless strap screwed down to the stringer and then clamped to the muffler would be EASY though.

        • Bronze pipes going into mufflers will need a compatible metal strap or support to eliminate/reduce electrolysis. A metal saddle shaped like an open oarlock and drilled and glassed into the top of the stringer would work. I don't see a need for a vertical tie down strap.

            Bet you those are fiberglass pipes.

              Yup. All fiberglass including mufflers.

              Had not occurred to me to glass something in... so is there no need to allow them to move? If they don't need to be allowed to wiggle then I can come up with something more simple.

                  Sorry, what'd I miss here....? Getting a slip downtown? I thought you were planning on trailering this beast.

                    haha, we'll see how easy it is to launch/retrieve but I'm thinking of leaving it moored half of the year for convenience either downtown or at Suldans. How many boat dollars I spend between now and then will factor as well!

                        Technically not boat progress, but these will make using the bottle jacks on the keel a little less sketchy walking the boat off the trailer.

                          • Got some good news from an interlux rep. For gelcoat only blisters(not sure this is the right word for what they are anymore), he recommended opening up the cracks and coating with 2000E, then fairing with watertite as needed, followed by 2000E. This is good news as I had previously thought I needed to resin seal before fairing with watertite, and then I'd have to deal with the blush of resin before fairing. The 2000E just needs appropriate dry time and a quick scuff.
