Thoroughly agree with the last 3 posters on St Pierre - it's a super little place and the anchorage is fine - you just need to be careful precisely where you drop the hook.

Lovely scenery, picturesque town, hassle-free Customs clearance, amazing museum with relics from the Mont Pelée eruption, and an incredible place for divers - the Martinique Government has recently designated a large protected dive area - I've dived on one of the shallow (but still damned deep!) wrecks that went to the bottom after the eruption - there are many wrecks from that eruption and you can still find things like melted glass bottles
