I've seen worse stains than that after only a weekend on our lake. Much worse if left for a month or so in the water. It could be anything from algae/slime in the water to too many 2 cycle motors burning 2 cycle oil. I've seen worse than that after 2 minutes exposure to the water at the launch ramp. A green scrubby pad and some soap and water would do wonders. Looks like a clean boat.....a diamond in the rough? Finding one parked in the weeds like that is a plus as far as price goes. BTW, what are they asking for it? On that one stain above the waterline, if you inspect the interior under the bunks, you will be able to see the inside, opposite of whatever that is. Look for cracked gelcoat radiating away from a center (what would be the inside area of a point of impact). If nothing on the inside, I wouldn't worry too much about the outside.

Dear members,
the boat I am looking at buying (1975 M-17) has a mysterious deposit just above the waterline, see the photo at

Can anyone guess what it can be? The boat spent most of the last few summers (except for the last one) docked on a fresh water lake in Utah. What is very strange is that the deposit appears to exist only *above* the waterline. Do you think it could be some kind of minerals from the water (e.g., iron, calcium)? How hard would it be to remove such a deposit? Or a mold, that grows on humid gelcoat, but not in the water? Could it have damaged the gelcoat?
Despite the fact that the boat has been in storage for the last year and a half, I know from sailing pictures of the former owner that the deposit was there at the end of the last summer when the boat was sailed, two years ago (photo was of the boat in the water, sailing, and one could see the deposit at the bow).
Thanks,
Andrei.
