Cymru, glad it turned out relatively easy (so far). In the 7 or so years we had SeaTow and never used them, last year when we went to T inboards and got grounded driving her home, the one ungrounding would have been nearly $800 ; that paid for 5 years worth of coverage right there. BoatUS/SeaTow is cheap insurance, well worth it.
Interesting fact that we found out parked next to the County Police Marine boat (tidal NE, Freeport, NY); they will tow for free. Also found out it is legal to drink and drive a boat, just not intoxicatingly so above .08 (and not flaunting it, asking for trouble).
Prior boat: 1999 Maxum 2400SCR (I loved that boat but the wife made me get bigger). Current: '96 Carver 325 aft cabin.
