We took the Nekton Pilot in January. Flew into San Juan, PR...They arranged for a van to take us to the marina about 45 minutes away...Shoved off when everyone was on board (they had to wait on me because my luggage was 6 hours late)...overnight we traveled to St. Croix, USVI and dove, dove dove...2 morning, 2 afternoon and a night dive daily...plenty of variety.
Nitrox is available for extra charge...Food is great and plentiful...staff was terrific and hlepful...the boat is very weird looking but very stable and the dive deck lowers right to the water...they have a good website if you want to check it out. Good luck
