Bermuda was grazed in Sept. of 1999 by Hurricane Gert which blew winds at the island of up to 110 miles per hour, the ships all left the Island early that week.
In 1991Hurriane Grace formed in the warm waters off Bermuda, between there and the Carolinas. This was the progenitor of the "Perfect Storm". While not affecting the Island directly it certainly affected the area that a ship would sail through between Bermuda and New York.
In 1987 Hurricane Emily hit Bermuda causing 35 million in damages.
However, more tropical storms pound the U.S. mainland than hurricanes devastate Bermuda. And islands in the Caribbean are much more likely to be hit by a hurricane than Bermuda is. Satellite forecasts are generally able to give adequate warning of any really dangerous weather so that precautions can be taken in time.
Ships will take evasive action moving away from a storm to other locales. In this regard it is better to be on a cruise then to be a sitting duck at a resort that is on a direct path with a storm. But pack accordingly because two years ago some folks who thought they were going to Bemuda wound up in Nova Scotia.
It is more likely that you will have some mixed sea conditions and a great week on the island.
Go and enjoy.
