Re: You are NOT "FISHING"
Agreed. "I caused/was willing to cause thousands of dollars worth of damage and risked lives to save $300 worth of lures and lines"" is probably not a persuasive argument.
Risked lives? If the sailboat was just drifting along I doubt any collision that did more than mar the paint was possible.
If you could factor out the Sail v. Power portion (you can't, but...) I would think a commercial vessel, pursuing its livelihood, with some degree of restricted movement, would/should have rights over a recreational vessel out for a fun day on the water.
