HAVANA, March 28 (Reuters) – Two sailboats carrying humanitarian aid from Mexico reached Havana safely on Saturday, according to the Mexican Navy. Their journey faced delays due to bad weather, and they were briefly reported missing.

The navy confirmed that the sailboats docked securely in the Cuban capital after local authorities tracked their final approach.

After being reported missing on Thursday, a maritime surveillance aircraft located the sailboats on Friday, about 80 nautical miles (148 km) northwest of Cuba. The crews checked in and stated they were in good health, though they experienced slow progress because of challenging weather conditions, particularly strong winds.

The two boats are part of a convoy aimed at delivering food, medicine, baby formula, and other essential supplies to the largest island in the Caribbean. This comes in light of a U.S. blockade that has restricted shipments of oil and other materials, worsening power outages and prompting the Cuban government to ration services.

According to a spokesperson for the Nuestra America Convoy, “The vessels are continuing their journey to Havana. The convoy is on track to fulfill its mission—providing urgently needed humanitarian aid to the Cuban people.”

The sailboats were reported missing after they departed from Isla Mujeres, Mexico, last Saturday, with an expected arrival window in Havana between March 24 and 25.

The U.S. Coast Guard initially informed the French press agency AFP on Friday that the boats had been located but later corrected itself, indicating that the search was still ongoing, which caused some confusion.

The Nuestra America coalition, which translates to “Our America” in Spanish, consists of almost 300 organizations from over 30 countries, including NGOs, unions, political parties, and lawmakers.

This group has successfully delivered around 20 tons of aid via air and sea to Cuba, supplying food, medicine, solar panels, and bicycles.
