Hi Rapscallion
At high tide the reef is completely covered, so the lagoon is pretty much unprotected.
The sandy bottom between bommies affords good holding so, if your anchor is dependable, it's doable but it will be rolly and uncomfortable in anything more than about 12 knots.
Many anchor in the lee of the island on the western side in suitable conditions.
It is, however, heaven on a stick out there and not to be missed.
Definitely aim for slack water to enter the lagoon.
Hope you get out there
