International trade thrives on the backbone of the shipping industry, serving as the critical link between producers and consumers across the globe. By enabling countries to specialize in specific industries and trade their excess production, shipping drives economic growth and improves living standards worldwide.
The industry also supports millions of jobs, ranging from shipbuilders and port workers to logistics specialists and maritime insurers, making it an essential pillar of the global economy.
The International Maritime Organization (IMO) highlights the significance of maritime trade, noting that 90% of the world’s cargo is transported by sea. Shipping goods via cargo vessels is not only highly cost-effective but also indispensable for moving a vast array of products, including food, electronics, and oil.
This process is a cornerstone of international trade finance, ensuring that goods reach markets efficiently and at scale. Marine finance, a niche within equipment financing, plays a pivotal role in sustaining this industry.
It encompasses funding for various types of vessels, including dry bulk carriers, tankers, and container ships, each with carrying capacities measured in Deadweight Tonnage (DWT). To better understand this, let’s delve into the diverse types and sizes of vessels that power the global shipping network.

Dry Bulk Carriers
Dry bulk carriers are vital for transporting large volumes of dry goods, with these vessels categorized into eight distinct size classes.
Handysize Vessels
Handysize vessels, the most common bulk carriers over 10,000 DWT, boast a carrying capacity of 15,000 to 35,000 DWT. Measuring 130m to 150m in length with a draught of 10m, they are equipped with five cargo holds and four on-deck cranes for versatile storage and efficient loading. Their shallow draught and compact size allow access to most ports worldwide. These ships typically transport goods such as iron ore, coal, cement, phosphate, finished steel, logs, fertilizer, and grains. They are predominantly built in countries like Japan, South Korea, China, Vietnam, India, and the Philippines.
Handymax Vessels
Handymax vessels are a step up from Handysize, with carrying capacities ranging from 35,000 to 48,000 DWT. These ships measure 150m to 200m in length with draughts between 11m and 12m. Like their smaller counterparts, they feature five cargo holds and four on-deck cranes, making them suitable for ports with limited infrastructure. Handymax vessels primarily transport iron ore, coal, cement, finished steel, fertilizer, and grains. They are most commonly constructed in Japan, South Korea, and China.
Supramax Vessels
With capacities of 48,000 to 60,000 DWT, Supramax vessels are medium-sized carriers ideal for accessing smaller ports thanks to their 12.2m draught and 199m length. These vessels provide a balance between size and flexibility, making them a popular choice for diverse cargo needs.
Ultramax Vessels
Ultramax bulk carriers are an upgrade from Supramax vessels, with capacities typically ranging between 60,000 and 65,000 DWT. These medium-sized vessels offer enhanced performance and efficiency, catering to increasing demand in the shipping industry.

Panamax Vessels
Designed to pass through the Panama Canal, Panamax vessels can carry between 65,000 and 80,000 DWT. These ships typically have seven cargo holds and adhere to canal regulations, with dimensions reaching up to 366m in length, 49m in width, and 15.2m in draught. They are commonly employed for transporting goods within the Caribbean and Latin America.
Kamsarmax Vessels
Kamsarmax vessels are specialized carriers with capacities of 80,000 to 85,000 DWT. Their design accommodates both the Panama Canal and Port Kamsar in West Africa, making them a versatile option for regional and international trade.
Post-Panamax Vessels
Post-Panamax ships are larger than Panamax vessels, with capacities ranging from 85,000 to 110,000 DWT. These vessels are also built to navigate the Panama Canal while offering greater carrying capacity for bulk goods.
Capesize Vessels
Capesize vessels represent the largest class of dry bulk carriers, with lengths between 230m and 270m, draughts of 17m, and nine cargo holds. With capacities of 110,000 to 200,000 DWT, these massive ships are primarily used for transporting coal, iron ore, and raw materials. Due to their size, they can only dock at select ports, commonly operating routes between Australia and China or Brazil and China.
Tanker Vessels
Tanker vessels are designed to transport homogeneous liquid or gas cargo, including fuel oil, diesel, kerosene, edible oils, cycle oils, bitumen, gasoline, paraffin, wines, and molasses. These vessels operate at relatively low speeds, with a maximum cruising capacity of 15.5 knots, powered by large marine diesel engines. Unlike other ships, tankers are not restricted by space constraints, making them ideal for transporting bulk liquids efficiently.
Tanker classifications are based on deadweight tonnage (DWT) using a flexible market scale rather than the fixed AFRA scale. These vessels fall into five primary categories:
Handysize Vessels
Handysize tankers, with a carrying capacity of 10,000 to 40,000 DWT, are the smallest in this category. Thanks to their compact size, these ships can access ports of all sizes, offering versatility in cargo delivery.
MR (Medium Range) Vessels
Medium Range vessels have a capacity of 40,000 to 55,000 DWT and are commonly used for shorter-distance cargo transport. Typical routes include shipments between Europe and the East Coast of the United States.
LR1 (Long Range 1) Vessels
LR1 vessels are medium-sized tankers with capacities ranging from 55,000 to 80,000 DWT. These versatile ships can carry both refined products and crude oil, making them one of the most frequently used vessels in the tanker fleet.
Aframax Vessels
Aframax tankers, approximately 245m long, have a capacity of 80,000 to 120,000 DWT. They are ideal for short- to medium-haul crude oil transport, especially in small harbors that cannot accommodate larger vessels like VLCCs. Common trade routes include South America to the U.S. Gulf through the Caribbean, North Africa to Southern Europe via the Mediterranean, and Southeast Asia.
Suezmax Vessels
Suezmax tankers are the largest ships that can transit the Suez Canal, measuring roughly 285m in length with a capacity of 120,000 to 200,000 DWT. Their beam typically ranges from 50m to 77.5m, and modern builds feature a draught of up to 21.95m, exceeding the previous limit of 18.90m before canal upgrades.
VLCC (Very Large Crude Carriers)
VLCCs, often called Supertankers, are among the largest tanker vessels, with capacities of 200,000 to 320,000 DWT. Standard dimensions range between 300 and 330m in length, with a beam of 58m and depth of 31m.These ships are designed for long-haul crude oil transportation from regions like the Persian Gulf to Europe, Asia, and North America. VLCCs are also frequently utilized in the North Sea, Mediterranean, and West Africa, and they can traverse the Suez Canal for efficient global trade.
Container Vessels
Container vessels are specialized ships designed to transport cargo efficiently using standardized shipping containers. These vessels vary in size and are categorized into four main types based on their carrying capacity.

Feeder Vessels
Feeder vessels are the smallest in the category, with a capacity of under 3,000 TEU (Twenty-foot Equivalent Units). These ships are primarily used for short-haul journeys, ferrying cargo between smaller ports and larger “mother vessels” that handle long-distance transportation.
Intermediate Vessels
Intermediate vessels fall into the small to medium size range, with a carrying capacity of 3,000 to 7,999 TEU. They are ideal for regional routes and serve as a bridge between smaller feeder vessels and larger transoceanic ships.
Neo-Panamax Vessels
Also known as New Panamax vessels, these medium to large ships can carry between 8,000 and 14,999 TEU. They are specifically designed to utilize the expanded dimensions of the newer Panama Canal locks, enabling greater efficiency and capacity for global trade.
Post-Panamax Vessels
Post-Panamax vessels are the largest container ships, with capacities exceeding 15,000 TEU. These ships are too large to transit the Panama Canal and are primarily used for high-volume routes between major international ports.
Conclusion
Whether it’s dry bulk carriers, tankers, or container ships, every vessel contributes significantly to the movement of goods worldwide. From the versatile Handysize to the massive Capesize, and from the agile Handysize tankers to the colossal VLCCs, each ship type is meticulously designed to handle specific cargo and navigate particular trade routes. The next time you spot a ship on the horizon, take a moment to appreciate the indispensable role it plays in keeping the global economy thriving.
