Dents in hull-repair?
I have a 24 foot sailboat that was improperly placed on its cradle. The
weigh was placed in an unsupported portion of the hull and has resulted in what looks like a dented can. The boat sat in this position for many years. The dents have remained even with completely shifting the boat in the cradle. I can get to the hull from behind / inside. What is the best way to repair this? John |

Dents in hull-repair?
John,
The creep (cold flow) that is a constant threat to almost all plastic is a very temperature sensitive issue. If you can wait until the weather warms the hull, it may well recover on its own. Or, you can heat it locally with a jet heater and pull it with one of those suction holders, but just letting it sit in the warm is the easiest thing to do - those that I have seen usually come back.

Dents in hull-repair?
Can I help it along with some constant pressure from behind? I am very
inspired by the thought of not having to cut and grind. "Matt Colie" wrote in message ...

Dents in hull-repair?
John,
If you can get behind it and push it will help, almost anything will help. Heat (gentle) helps most. An acquaintance some years ago brought a thin glass canoe back to shape by filling it with hot water. The great joke came when he wanted to grab one gunwhale and heave it up to get the water out. (Hint: a canoe full of water is about 1500#) Interest on my part - What is the boat? Matt Colie John Cassara wrote: Can I help it along with some constant pressure from behind?

Thanks Matt the boat is a C&C 24 check out the pics. I intend to block a small hydraulic jack inside and warm the outside with a heater and jack some gentile pressure to shift it into shape.

Use the sun to your advantage. Put the boat where it will receive the afternoon sun and take your time. Inch by inch, row by row, watch my garden grow, and my hull pop back into shape. Have fun.

John,
Looks like you have a good project there. At least you have a hull that is worth the effort. The Dents that show in the pictures are not real bad, I have seen worse just come out on their own. Heat and pushing will help. Take care around those cracks in the deck by the chainplate. They could have let water get into the plywood under the deck. A soft face hammer will tell you just how much trouble you are in (from a guy that carries a 500$ moisture meter and a 10$ hammer). I'm here a lot, so, if you have other questions I might just have more answers.
