The ship in heraldry is a venerable symbol of exploration, commercial enterprise, and the ambitious spirit that connects distant worlds. It represents a family or community’s ability to navigate the "seas of life" with courage and skill, emphasizing a legacy of successful ventures and the expansion of influence through travel and trade. Traditionally, the ship stands for the state itself—the "Ship of State"—signifying stable governance and the collective destiny of a people under the guidance of a wise pilot. In private arms, it serves as an emblem for those whose ancestors were noted naval commanders, merchant princes, or pioneers who established new homes in far-off lands.

Common associations for the ship center on maritime identity, civic prosperity, and professional achievement. Coastal cities, major ports, and island nations almost universally adopt the ship to proclaim their strategic importance and historical reliance on the sea for wealth and defense. In a military context, specific vessels like the "lymphad" or ancient galley appear in Scottish and Nordic heraldry to denote clan authority and the mastery of northern waterways. Occupational links are prominent among shipbuilders, sailors, and international traders, where the vessel reflects a life dedicated to the hazardous yet rewarding business of maritime transit. It also appears in religious heraldry, where the ship symbolizes the church providing safe passage through the storms of the world.

The meaning of a ship is modified significantly by its type and state of sail. A ship with "sails furled" indicates peace or a mission accomplished, while a ship "under full sail" signifies active pursuit, progress, and the vigorous seeking of fortune. The lymphad, often depicted with oars in action, emphasizes self-reliance and the ability to move regardless of the wind. A ship shown "in distress" or tossed by waves can commemorate a miraculous survival or a period of extreme trial successfully endured.
