Following up on Yachtmaster's comments, the NPS allows vessels less than 60' LOA to anchor from 6 am to 6 pm for up to 3 hours. I've anchored a catamaran near the old seaplane ramp with no problem and I've seen monohulls anchored in there. As mentioned, the anchorage is red-lined for some charter companies.

I brought a catamaran to the Customs dock about 10 years ago and was charged $0.30/foot wharfage fee. The VI Port Authority Marine Tariff schedule shows the fee is now $0.60/foot.

Just curious - do you know of anyone who has been stopped by the USCG in USVI waters for operating an overloaded dinghy (most likely without lifejackets, signaling device, etc)? I think most 11'-12' RIB dinghies are rated for 4-6 persons, not the 8+ persons often seen riding in these dinghies in the BVIs.
