The last two times have been on a 38' powercat for me and we did the run from Great Harbor to Leverick. And we ran from Anegada to JVD a few days later. I don't remember how long it took us but I do remember it was a really pleasant ride on both trips and went by quickly.....it is definately NOT "too long of a haul" even if you were to stop and snorkel somewhere. But, I say that because the way I have always planned my schedule is to get off the ball/dock early in the morning so I arrive while a lot of the other folks are just leaving and spent the day exploring or whatever. Enjoy.
