I used to charter Grand Banks from Chitwood, and that was 12 years ago+. Always had very good experiences, though you had to be very clear about what you wanted, for instance a dinghy. Or in the summertime, unlimited use of the generator, and early June is summer down there. Great time to cruise as it is off season. But that was then; call them up and have a chat. There used to be a poster on this forum BillIII (as I recall his handle was here) that is professional captain that worked for Jerry Chitwood for awhile.
We are going to get back into chartering and I wouldn't hesitate to use either firm. Southwest used to have a Krogen in the fleet.
