    Hello everyone, I am looking for suggestions and resources to aid in my restoration of a 26ft Cy Hamlin Controversy. Due to neglect She has considerable dry rot in the hull. Can anyone suggest techniques?

    Thanks

    There are a number of techniques and methods you can employ, but the broad scope of the subject makes this format less then ideal. Strip planked hulls are difficult to repair, generally. Specifically, if you could supply photos and more precise explanations of your issues, we could offer application specific direction. The first thing I would do is call a qualified surveyor and have her looked over.

    Nojjan All thumbs...

    What has caused the dry rot? I thought epoxi covered wood was very resistant to all types of rot?

    The Controversy series was developed in the fifties in Mt Desert Island, Maine. The method was developed long before epoxy became popular. the hulls were built using something like 3/4" strips mailed together with bronze ring nails and glued with resorcinol.
    Strong hulls, and generally long-lasting. Repairs, however, are less than easy to do. The nailing was done in stacking fashion, one layer at a time, so of course you can't know where the nails are hidden. The strips can't be just removed in rectangular blocks and replaced. A certain amount of weaving is required to achieve enough strength to equal the original build.
    This is where the headaches begin. No two repairs will be the same because each area of the hull presents a different challenge, and maybe a different method as well.
    I believe this boat would be called an Amphibicon, a centerboarder with the board in the shoal keel under the sole. Rot would likely start from rainwater settling around the lowest part of the hull, around the centerboard cover.
    If the damage is limited to this area, then it might be possible to build in a repair from the keel out. It would be a good idea to get a surveyor or qualified person to look at the boat before spending too much blood and treasure on the project.
    Pictures would help.
