If your tramp is tight and the hulls and frame are still loose, you probably need to use shims. In order to do this you'll have to take the boat apart.
Go to the upper right hand corner of this page where it says: " Faq Search Members User Control Panel " and click on Search. Then type in "shims". Some shim with epoxy; some with brass; some with aluminum....... I shimmed mine with Brass last year. If yours are miss-matched hulls and are really loose, I'd probably use epoxy resin with fiberglass cut up and mixed in with the resin. It'll be semi permanant, but very stiff. This is also a good time to do a bottom job if necessary. The boat is already apart. Clean the outside of your pylons and the insides of your corner castings. Check to be sure the vent tube is still inside of the foam in the two front corner castings.
Check the holes where the bolts hold the pylons and corner castings together. if elongated, repair as best you can - (resin and fiberglass???). There is no one "correct way" to do this, so be creative.
If you shim with resin and fiberglass, align hulls by measuring diagonally - port bow and starboard stern; starboard bow and port stern. Do this before resin sets up and hardens.
Visualize the whole project through BEFORE you start working to be certain you understand what you're going to do and you have all the necessary materials.
Get a friend, or son, or strong wife to help with the heavy lifting.
This isn't a difficult project. It's kinda fun. I did this last year and I'm not mechanically inclined.
Also, check for soft spots on your hulls (de-lamination), check your shrouds, forestay, trap wires, anchor bolts.... Repair and replace as needed.
DON"T seal the front corner castings/pylons completely!!! Remember that vent tube in the foam of the front corner castings??? The hulls have to breathe - expand and contract with warm and cold weather.
Remember-be creative and use good judgement. Your boat should be aligned, strong, light weight, and safe for you and your family and friends.
Good luck and enjoy your project!
