Re: Help pinpointing a leak
I also have a 35/3. The keelbolt in the photo is not original - its too clean and shiny. It also looks taller than the original. Is there some sort of sleeve under the washer? Its possible someone already tried to rebed the keel and did a lousy job.
Technically, the supports that run laterally are "floors". Stringers run fore and aft.
If it were a wood boat, I'd say use the sawdust trick - put lots of sawdust in the water and let it get sucked into the source of the leak. Doesn't fix it, but stops the water.
