Often confused with “collision,” an allision has specific attributes that set it apart. In this article, we explore the definition of allision, shedding light on its unique characteristics.

Defining Allision

An allision refers to a maritime incident where a moving vessel, such as a ship, boat, or barge, collides with a stationary object or structure. Crucially, in an allision, the object being struck is immobile, and it is the vessel itself that is in motion. This distinction sets allisions apart from collisions, where two or more moving vessels collide with each other.

Types of Allisions

Allisions can encompass a wide range of scenarios, depending on the type of stationary object involved. Common types of allisions include:

• Dock Allision: When a vessel strikes a dock or pier.
• Wharf Impact: Involves contact with a wharf or quay.
• Bridge Allision: Occurs when a vessel collides with a bridge, often leading to damage to both the vessel and the structure.
• Buoy or Beacon Allision: Involves striking navigational aids such as buoys or beacons.

Each type of allision comes with its own set of challenges, implications, and potential consequences.

Navigational Challenges

Allisions are often the result of navigational errors, equipment malfunctions, adverse weather conditions, or miscommunications between vessel operators. Navigating waterways safely requires precise calculations, adherence to maritime rules, and constant vigilance, making the prevention of allisions a top priority.

Legal Implications

Allisions, like any maritime incident, have legal and insurance implications. Determining liability in allision cases can be complex, with various parties potentially sharing responsibility. Legal proceedings and insurance claims may follow, requiring expert legal representation and comprehensive investigations to ensure fair outcomes for all parties involved.
