The only thing that would limit you would be the seas. It is all pretty wide open seas till you are close to the island. As a fuel stand point the North is a more direct straight line. AS far as lobster..you can get Anegada Lobster anywhere in the BVIs. Have found it cheaper on other parts of the BVIs than in Anegada. To be honest its the same and cant tell the difference. I will never make the mistake of going there just for the lobster just for that reason. Lots of other reasons to make the trek.
