Bucks is nice but crowded (is the Outback still there?) - I prefer Lems a little to the East.
Another harbor I can recommend is near Boothbay at 43deg 50.6N 69deg 38.8W - the marina at the S end of the cove (name?) offers moorings, parking and dingy space. Might offer a shorter drive for most folks? Sorry Larry, no idea about cell service or wi-fi.
