Inter‑island freight inefficiencies
Social posts from the last 48 hours highlighted on‑the‑water delivery patterns and disruption: Jamaica reported Carnival logistics impacts from Hurricane Melissa, and a former sea‑tug worker described barges dropping CONEX boxes across islands and routinely facing empty return legs. (x.com) The same thread referenced larger logistics thinking from grain‑and‑commodity operators on efficiency at scale. (x.com) (x.com)
Recent posts about Jamaica and other island routes pointed to the same freight problem: ships can reach small ports, but too often they leave with little or nothing on the return leg. (jamaica-gleaner.com) (unctad.org) One example came after Hurricane Melissa. On December 18, 2025, the *Jamaica Gleaner* reported that Carnival Horizon delivered 24 pallets weighing more than five tons to Reynolds Pier in Ocho Rios as part of Jamaica’s recovery effort. (jamaica-gleaner.com) That shipment followed an earlier relief call on November 4, 2025, when Carnival Horizon stopped in Ocho Rios with bottled water, baby food, diapers, canned goods, cereal, and hygiene supplies for Jamaica’s disaster agency. Carnival Cruise Line said the stop was made to support Hurricane Melissa relief efforts across the island. (carnival-news.com) Inter-island freight works best when a vessel earns money in both directions. The Caribbean Development Bank said in July 2024 that the region still struggles with limited berthing capacity, high shipping rates, outdated tariffs, long inspection times, aging port infrastructure, and inefficient labour practices. (caribank.org) Those constraints are sharper in small-island networks, where each port handles less cargo than a major mainland gateway. United Nations Trade and Development said on October 22, 2024 that small island developing states had seen a 9% decline in maritime connectivity over the previous decade, while port handling charges in Caribbean ports were two to three times higher than in similar ports globally. (unctad.org) Regional officials have been arguing that the fix is not just more ships. The Caribbean Development Bank said governments and operators need digitalisation, stronger public-private coordination, and cargo hubs that can create economies of scale across multiple islands. (caribank.org) Food trade studies have been making the same point in narrower lanes. A December 2023 regional study for the Food and Agriculture Organization and the Caribbean Development Bank examined a proposed maritime service linking Guyana, Trinidad and Tobago, Grenada, and Barbados to improve agrifood trade and food security. (agricarib.org) The comparison to grain and commodity logistics comes from a bigger system with steadier volumes and tighter data. The United States Department of Agriculture’s Grain Transportation Report tracks weekly barge, rail, truck, and ocean-vessel movements and prices, giving large operators far more visibility into how to fill capacity. (ams.usda.gov) Global shipping conditions have made the small-route problem harder to solve. United Nations Trade and Development said in its 2025 *Review of Maritime Transport* that maritime trade growth was set to slow to 0.5% in 2025 and that longer rerouted voyages had already pushed ton-miles up 5.9% in 2024. (unctad.org) So the freight story behind those posts is less about a single storm or a single barge run than about scale. Small islands need regular service, but regular service is hardest to sustain when cargo arrives in bursts and the return trip sails half-empty. (unctad.org)
