I have had BoatUS unlimited for 3 years or so, used them once. (knock on wood) No problems. Fast response and we were on our way (jumped my battery for me) They keep a boat close to my inlet.

I am sure there are areas as stated above that it may be better to use SeaTow. Check your local listings.

I have unlimited also, you can add a second name to your BoatUS card, I have my brother listed and that covers him also, he gets a card also, same price.
