We bought it back when we had a camper that we pulled behind our vehicle, and could not trailer a boat. Now my family has a beach home, and I got a small trailer so it is much easier to use.
I have driven that boat some long distances. I went from my aunts house on lake George(Huletts Landing) down to the village this past summer to visit a friend. 21 miles one way. Trip down the water was glass, but 1-2 ft. waves for the return. When i am down at the beach I like taking it out in the ocean as well.
I went out in Buzards Bay with my dad's friend in his Zodiac following a hurricane when there was still 4-5 seas. Had a total blast jumping the waves.
Great Bay is pretty huge and dumps out into the ocean. I'd guess it would be about 15 or so miles from the launch in my downtown to get to the Atlantic. Geoff would know. I'm sure he's cruised Great Bay when he lived in the area.
