The U.S. Coast Guard Air Station Miami spotted the rustic vessel 38 miles south of Key Largo, an island part of Monroe County, Fla., located in the upper Florida Keys.
A Coast Guard crew based in Islamorada intercepted the boat and found the five Cubans on board, the station said on Facebook. All of the boat's passengers were male, the Miami Herald reported.
The occupants of the boat were transferred to the Coast Guard Cutter Charles David Jr., a vessel assigned to serve in Key West. The five will be brought back to Cuba.
In May, the Coast Guard intercepted a boat with 10 Cuban migrants and two smugglers on board, 12 miles off the coast of Villa Clara Province, Cuba. The crew repatriated the 10 Cubans. The two suspected smugglers were transferred into the custody of Homeland Security, the Herald reported.
