Re: Help with pre-1972 rudder mount


 

Not a fan of toggle bolts anywhere on a boat: ?they are made to work only in tension, not shear or compression, their prongs concentrate stress on small points ?- which is bad if it's on the actual fiberglass... less bad if resting on a backing board of some kind... but they also corrode pretty quickly unless made of the right materials. ?These did a number on the footrails of my Butterfly scow when the previous owner used them, so I have a bad relationship with them, I mean hate them hate them hate them. ?Your mileage may vary.

I had the problem with my old style rudder.? Go ahead and put in the inspection port now.? It is a pretty easy job.? Then you can thru drill the hole and put on a nut and washer.? If you after the season decide to convert to the new style rudder, the port will already be there? If the wood is not too rotted, you can jam a piece of wood in the hole and rethread in the screw.? I have done that many times on things besides boats were a hole is rotted or just worn out.? I scored on a trade the rudder hardware so I converted mine the? spring loaded style as opposed to the break away style.

Being that the only good place for a inspection port is right where the older style rudder mounts, Idk that I would go to the effort to install an inspection port to fix a backing board on an older style rudder. I would first epoxy the hole and re drill the hole. If that didn’t hold I would use an expanding fastener. The rudder mount in that area is not a high stress area. If the rudder is attached correctly, it would not need much to hold it.?

If none of those options worked Then I would decide on if I liked that boat enough to update the rudder.?

Having said that. There are lots of good reasons to install the inspection port and update the rudder. But that’s a bigger decision.?

That 50 year old backing board inside the hull is damaged.? Best to install a 6" inspection port in the middle of the back deck and replace the board.? Yes,? epoxy the hole in bottom of boat.? Redrill and install bottom bracket,? use a good glob of silicone sealer in the hole.??

When I've gotten to this point is when I've converted to modern stainless transom mounted rudder gudgeon bracket and modern kick up ruder system,? but that's an investment.? If you're recreational sailing,? not worth it.? ?

Over the winter if you can store the boat someplace secure (no rodents/insects) and even slightly warm,? leave the inspection cover off so the hull can dry out.? If you can circulate air,? all the better.? It is possible to get the boat back to 130 pounds,? I've done it.?

Good luck.?
