Ditto on leaving where you are early and arriving to your next destination early. You'll enjoy the afternoon in your new location and not have the drama of trying to find a mooring at the new anchorage lat in the day. For some unexplained reason, I have never chartered a boat in the BVI's that had the anchor chain marked, so you'll be trying to figure out how much scope you have.Easy as others have explained. Your guest will love it. I encourage you to get to the bay as early as you can to maximize your odds of finding an empty mooring. My rule of thumb was also before 2pm in the BVIs. As crowds build, it can get earlier and earlier. Noon should be very safe and very doable from BEYC.
Have a great trip. I envy you!
