George is right on.

We just arrived back home after two weeks of sailing the BVI

Passing Scrub, we changed plans of a slip there, we elected to pick up a mooring at marina cay. There were many , many masts visible and vessels at the Scrub Marina.

Actually, there were additional Dream Charter's catamarans , moored or anchored , not occupied , just off marina cay. pretty good indicator that Scrub was filled with Dream Yacht Charters boats.

Scrub did not look like there was any guest slips available in their marina. Those dates were May 18 and 19. Marina Cay was great for us, totally easy going, good meals, and drinks, not crowded.

However, all is not lost....the scheduled free ferry runs all day into the night from Trellis to Marina Cay to Scrub, and returns. ( maybe 5 minute passage ) So, you can still visit scrub, while moored at Marina Cay.

Note: the best in shape mooring balls at Marina Cay, that we observed, were on the south west end of the mooring field. Also, Marina Cay, is a nice base for a 30 minute motor
over to Monkey Point , Guana island, for snorkeling. ( free N.P. Moorings for 1.5 hrs. )

Have fun.
