HELP!!! Boat Down!!!
I agree with the others. Fixing would probably be much more than the boat''s value. I just got a "deal" on a 27''er last spring that was flooded on the trailer by rain and a plugged cockpit drain. She only had about 2'' of water in the cabin, but it is turning out to be much more expense and work than I had first planned! I can only imagine what a full submersion could damage. I think you should get her out of the water A.S.A.P. I''m no environmentalist, but if she leaks 30 gallon of deisel fuel, the clean-up cost could be huge. I don''t know if your insurance would cover this or not.
Best of luck,
Please keep us informed of the outcome.
