Grenada was thought to be pretty much out of the hurricane area, it was hit in 1955, the previous hurricane being 1891
It looked pretty safe until 2004 when it was hit dead on.

Between 1877 and 1891 Grenada was hit by eight hurricanes.
Two of them went over the top in the same year.

Grenada does have some good hurricane holes.
Boats properly secured in the hurricane holes survived hurricanes with little damage.
Here follows a list of Grenada hurricane holes

Hurricane holes listed with the best first

Egmont Harbor is surrounded by high hills, the entrance  only 100´ wide and thus no sea can get into it.
This proved to be true in hurricane Ivan.
Properly secured, bow into the mangroves and stern anchors out, probably 100 boats could lie in this harbor in relative safety.

Calivigny Harbor also referred to as Old Harbor  one mile east of Calivigny Island was a major port in the late 18th century.
This harbor has such a narrow entrance and narrow outer harbor that no sea can get into it, but it is not protected from the wind.

Mt. Hartman Bay, Secret Harbor, like Clarks Court is open to the south, protected from the sea by reefs but completely open to the wind, however it is better than Clarks Court Bay as there is a much larger mangrove area than in Clarks Court Bay.
This means more boats can be properly secured bow on into the mangroves in Mt. Hartman/Secret Harbor than in Clarks Court Bay.

Secret Harbor is open to the south.
Boats secured to St. Margaret’s Marina did not fare well. Some were damaged, others sank.
This illustrated the point that it is extremely difficult to secure boats to docks in hurricane conditions such that they survive the hurricane with either no damage or relatively little damage

Clarks Court Bay gives good shelter but it is open to the south protected by reefs but not from the wind, again find a mangrove area and stuff the boat in.
The floating docks in Clarks Court Bay came adrift during hurricanes.
It is not possible to secure floating docks such that they will survive a hurricane.

Hog Island anchorage does not really look like a hurricane hole but amazingly a number of boats anchored in this cove survived the hurricane, at anchor.
Do not regard this as a hurricane hole as too many boats will be anchored out, in danger of dragging down on you and causing massive damage.
