Chief Magistrate Evaline Baptiste ordered the men to pay a nearly $900 fine after calling them "rogues and vagabonds.'' They made no comment after the hearing and police drove the men to the airport after they were released.
The two were aboard the Celebrity Summit cruise ship that had departed Puerto Rico on Saturday with about 2,000 passengers. The ship departed for St. Barts late Wednesday, leaving the men behind.
The cruise was organised by Atlantis Events, a Southern California company that specialises in gay travel. President Rich Campbell said Thursday that the outcome of the case would have been the same had it involved a heterosexual couple instead of two gay men.
"It had nothing to do with their sexual orientation and everything to do with their public conduct,'' he said. "I have been in contact with the guests and they are in good spirits.''
Dozens of islanders packed the courtroom in the capital of Roseau to attend the 30-minute hearing.
Dominica Tourism Minister Ian Douglas said that tourists should abide by local laws regardless of their religious or sexual orientation, and that cruise ship officials should make passengers aware of these laws.
"It cannot be the responsibility of Dominica to screen guests and tourists before they come into the country,'' he said. "It is expected that any time people come to a country, they will respect the laws of the country.''
Gay Caribbean cruises have been popular for several years despite hostility to homosexuality on certain islands, especially in Jamaica, Barbados and the Cayman Islands.
