{{Main|Coastal trading vessel}}
Coastal trading vessels are smaller ships that carry any category of cargo along coastal, rather than trans-oceanic, routes. Coasters are shallow-hulled [[ship]]s used for trade between locations on the same island or continent. Their shallow hulls allow them to sail over [[reef]]s and other submerged navigation hazards, whereas ships designed for blue-water trade usually have much deeper hulls for better [[seakeeping]].
