We have anchored may times in Eustatis Sound, mostly in the long cove shown near the top of this photo
Plenty of water
and safe if you can read the water
Also suggest Benures or Soldiers Bays, Norman Island, Key Cay on the south side of Peter Island, Salt
Island off the "village" if the wind
is in the southeast, Sandy Spit/Green Cay area east of Jost Van Dyke.
that are recommended day stops often clear out in the afternoon and can be fine overnight spots if the weather
is moderate and/or you are on a catamaran
Just remember that there are no "unknown" anchorages in the BVIs but its not necessary to anchor
on top of other boats every night.
