That might be difficult, especially if you're dealing with older community members who aren't necessarily registering their vessels, but identifiers.... Typically, all vessels are required to have a hull identifier number. Now, over time, that number tends to be removed by wear and tear. That would be something that the federal government could look into: mandating some sort of a tracking device, if you will, or a more robust hull identifier number, in order to locate those vessels.
I would disagree that the majority of the vessels we find on the west coast are pleasure craft. About half of the vessels we are removing are ex-commercial fisheries and other commercial vessels on the west coast of Vancouver Island. I'm sure that Mr. Roe and Mr. Banting can speak to that as well.
On the east side, I do know that there are quite a lot of abandoned sailboats. Maybe Mr. Roe can field that question and provide that answer.
