Re: Helms 25 Centerboard restoration

I can tell you original spec for the Helms 25 centerboard was 300 #, info straight from Jack Helms some years ago. As it happens, I have a Helms 25 for sale - (should be in the classifieds today.) Last time I looked, centerboard was in pretty good shape.

Re: Helms 25 Centerboard restoration

Does anyone know what coating Jack Helms used on the centerboard from the factory? Just curious.

Re: Helms 25 Centerboard restoration

Well, I finally finished my centerboard restoration. Got the boat back in the water, and took my first sail on it in the last two months.

This is what I started with.



This is the board after being ground, Oshpho'd, and sealed with a Por15. I am just starting to epoxy it here.


Here it is after epoxy before being wrapped with eglass and more epoxy.



Here is the finished product with ablative paint on it.

Re: Helms 25 Centerboard restoration

Very nice job! How did it sail? Did you happen to weight it before you installed it? Wondering how close to the original 300# it ended up.
Was the pin stainless in those early years or bronze or something else?
Did the pin ride in the fiberglass of the trunk or were there some type of bushings for the pin? What was the diameter of the pin? Was it hard to get it out?
Sorry for all the questions, but I never had to remove mine yet.

Re: Helms 25 Centerboard restoration

Hey Wayne!

I didn't weight it. I estimate that the metal was probably about 250lbs or so from the original 300. The epoxy and eglass weighed next to nothing so while it gave it structure, it couldn't have affected the weight much.

The pin is stainless and it is directly in the trunk as far as I remember. It was a bit of a mess around it as there was a ton of sealant of some sort under the two panels that cover the pin. I cut away enough to push the pin through. I am not sure what the diameter was. Maybe 3/4 inch? It wasn't too hard to get out. I just took a small metal dowel and hammered it through from port to starboard.

So one thing I learned in this process is that I should have squared the rear edge of the centerboard instead of trying to taper it. It vibrates at about 4.3 knots and the boat now sings a different song depending upon the speed and the angle of the board.
