Not sure about that. You'd have to start at the crack of dawn, make the stop at Monkey Pt brief and motor most of the time to get to the entrance with reasonable light, say 1 or 2pm. Even if there weren't any mooring balls left you can still anchor to the East of the field, good holding. It is doable but it will depend on prevailing conditions, crew and a little bit of speed. Maybe have an alternate of going to the North Sound if things don't go perfectly and steal a day from the plan just in case? If you've been to Anegada before you could plan to get in a little later but if it's your first time I think you'd be pushing it a little! Kinda depends on how you roll...
