We are on a 48' Powercat with Marine Max. We mainly do it so we can avoid the ferry issues and spend the first night and as much of the last day as possible out on the water since we also have them meet us on the return trip. It really makes it very easy on our guests when Kevin picks us up at the airport and drops us off at the dock in Red Hook as opposed to fighting the crowds for the customs check-in with the ferry. I know this won't apply to the folks on sail boats but we also save quite a bit on fuel by filling up at American Yacht Harbor or St. John as opposed to Hodges Creek. I think we saved over a dollar a gallon the last time we did it. We tend to get moving pretty early so on a previous trip we were able to start the morning in the North Sound, Stop at Peter Island for breakfast, Clear customs to check out at West end, Clear customs to check in in St. John, and then having the charter company meet us in Red Hook all while catching a 2:00 PM flight. Our guests are able to pack on the ride back and get cleaned up which has worked out well. Some of our crew are on pretty short itineraries so we are able to maximize every minute with this approach.
