Mexico's navy activated operations on March 26 after the boats missed their scheduled arrival window, with no radio contact or signals received; international cooperation has been enlisted to cover the maritime route.
The missing sailboats form part of the "Nuestra America Convoy," a volunteer-driven flotilla aimed at easing Cuba's fuel and power shortages through donations of food, medicine, solar equipment, and basic supplies; other vessels in the effort have delivered aid successfully in recent weeks.
Nine people of multiple nationalities were on board the Friendship and Tigger Moth, carrying targeted relief items.
