Castor Maritime is a small shipping company based in Cyprus that moves cargo around the world on large ships. It operates a fleet of dry bulk vessels, which carry raw materials like grain, coal, and iron ore, as well as tankers that transport oil and petroleum products. Its customers are commodity traders, industrial companies, and energy firms that need goods shipped across oceans.

The company earns money by charging daily rates to rent out its ships, a model called time charters or spot market voyages. Castor Maritime operates globally, with routes spanning major shipping lanes, but it remains a very small player in a fragmented industry dominated by much larger fleets. Its low return on invested capital and thin operating margins reflect the challenge of competing in a commodity-driven market where ship rates fluctuate with global trade conditions. The main risk is that falling freight rates — driven by oversupply of ships or slowing global demand — can quickly erase profits.
