1960 mahogany Mason with cold mold bottom
by: Graham

I used cold molding to replace the bottom of my 1960 Mason mahogany lapstrake.

I removed the old plywood strips, sistered or replaced the ribs from the waterline to the keel and rebuilt the bottom using three layers of 1/8 mahogany marine plywood.

The first ply was bonded to the ribs and subsequent plys were bonded to the previous layer.

The original bottom was 3/8 ply so the thickness was the same but the construction turned out to be enormously more rigid.

I was a bit worried that the new rigid hull would put stress on the ribs where the new bottom met the old lapstrakes so I filleted the joins of the lapstrakes to make the topsides more rigid.

I have been using the boat for about 10 years now and am very pleased with the result.

Boat has been sold
by: DON

I realized repairing this boat was beyond my talents and decided to sell.

After a year of looking for the right buyer the boat has been sold and went to Chicago to a Wooden boat restoration school to be used as a class project where students can learn wooden boat repair and restorations,

Thanks to all who commented and gave me advice along the way.

Charles Thanks for the Link.

That method is kind of of what I was thinking about doing, But all information I have gathered strongly suggests NOT doing it that way,Including this site!

Apparently the planking can move and will break the bond between the wood planking and the cloth/epoxy.

I would rather do this method rather than the cotton and putty.

Maybe others can chime in with their opinions, And experience.

Thanks Again

As of now I have done nothing, Except consider making a bar out of the boat. I probably get more use out of it that way anyway.


Re-planking vs cold moulding
by: Mike Cochran

I'd have to agree that replanking and epoxy sounds a lot easier.

I am renovating a 1957, P-28 which had a lot of hull problems.

It was a bit of work but is looking pretty good now.

Best of luck with your P-28.

Cold Molding
by: Mike

I’m sure it could be done, Don.

But how would you treat the joint between the cold molded section and the original planks?

I can’t help thinking that just replacing the planks would be a simpler job.

Or how about strip planking?
