Re: BoatUS towing or Seatow?
You need local info. As between the two, it does not matter one bit what someone says from outside your area. They are franchises and quality is dependent on the operator, not the company. And a bad franchise owner can be replaced with a good one, so get current local info. It's like asking, which is better, a Ford dealer or a GM dealer?
At the local level, compare what each offers and most important the distance limitations. Pick one that is closest to where you plan to break down and closest to your home base, since the all charge by time based on when they leave their dock. For that reason, I keep both numbers handy and would call one or the other depending on where I was when I needed them (I have a wide range here).
You don't have to be a member to use their services; you just have to pay for it in one payment instead of annual installments. For some it makes economic sense to pay annually, but not for everyone--especially when you factor in your boat insurance paying the first $500 or so (check your policy). or in my case, having the choice.
