What's up Dean?
I've got Boat-U.S. "Unlimited" Tow coverage for $99.00 per year. It includes coverage for any and all tows up to 25 miles offshore and 50 miles in any other direction from your home port. You also get Dock-to-dock coverage if your boat is not operational and you need to get it to a launch ramp or repair facility. It's great service and at that rate you really cen't beat it. Additional benefits are all the discounts you can get through them.
I would also strongly recommend them against that other tow company, simply because I know your beliefs and Boat-U.S. is strongly committed to and aligned with Boater's rights. You can read all about what they stand for and what they do on their site.
