Boat building turned away from wood in the fifties and sixties, I guess. If I could make a really big guess, we're looking at vessels that are probably from 1960 to 1980 that might be part of the problem today. We don't have the capacity to look into it at this point, as they're not coming to us to say what's abandoned. Again, I think it would require a study to look at what components there were from that time that might be hazardous.
What I know is that the engine is now built to high standards over the last several years, but what it was in the fifties and sixties and what spillage there is, I really don't know. I could look into it, but I don't know.
