Martinique said cruise traffic totaled 51,718 passengers from January to April, an increase of 10.5% over the same period in 2007.
Muriel Wiltord, director Americas for the Martinique Promotion Bureau/CMT USA, called the increase "a good start."
"With all that Martinique offers for cruise passengers, there's still a lot of room for growth," Wiltord said.
Cruise ships call at Fort-de-France, the island's capital city. Many of the shops offer 20% discounts for passengers using U.S. credit cards or traveler's checks.
Excursions highlighting Martinique's ecotourism attractions, culture, water sports and rum production begin and end in Fort-de-France.
