Mexico has deployed naval search teams and military aircraft to locate the Friendship and Tigger Moth, which were carrying at least nine crew members, the Mexican navy said.
The vessels had been expected to arrive in the Cuban capital, Havana, on Tuesday or Wednesday, but there had been no communication from them and no confirmation of their arrival, the navy said.
The two missing ships departed Isla Mujeres, in Mexico’s easternmost state of Quintana Roo, on 20 March.
The nine crew members are from Poland, France, Cuba and the US. Mexico said it has established contact with maritime rescue co-ordination centres from each country along with their diplomatic representatives.
