Another option. If you go up and down the coast, you might be able to find
an abandoned boat to refurbish. Not sure about up there, but in various
coastal areas you might find a boat with a hole below waterline, or similar
defect that could return the boat to operating condition with minor work.

Once saw a perfectly good jetski sitting here on our beach, only needed
minor engine repairs.

You'd be surprised what some people throw away.
