The suggestion to go with a
catamaran is very good. Most of the
eastern Caribbean Islands have enough wind to keep your
boat heading basically eastward while at
anchor. However, with a large enough island the waves/swells will "wrap" around the island and come at you from your beam resulting in constant rolling - sometimes very minor - sometimes rather annoying. Catamarans - especially the really wide ones - ride quite stable and flat during most of the time compared to mono-hulls. The only downside to cat's is the "hobby-horsing" they are prone to in moderate seas on the bow between islands. But inside the Grenadines that is rather rare.
- - If you cannot afford a
Catamaran, then in some less crowded anchorages you can deploy a stern
anchor to "pull" the bow into the swells to convert the rolling into pitching which is easier to take especially when sleeping.
- - Tyrrel Bay in Carriacou is subject to some dramatic swells during certain wind/wave conditions. The docks at the Lazy Turtle have to be removed during these times or they will be smashed. The northern side of the bay near the mangroves is a favorite for those wanting to avoid the rolling and sometimes boats
head into the little mangrove swamp itself to get away from the worst of the surge. But more than half the time, the bay is benign and really a very pleasant place. Snorkeling and
scuba diving around the little islands to the south is probably the best in the
Caribbean so if you are into that stuff don't miss Carriacou.
