Allision Definition:

A collision between a moving vessel and a stationary object.

In his maritime law treatise, Thomas Shoenbaum wrote:

"An allision is a collision between a moving vessel and a stationary object."

In Evergreen, the Justice Hamilton of the United States Court of Appeals noted that the claims before him:

"... stem from an allision between a container ship, the M/V Ever Reach, and a submerged dredge spoil pipeline located outside the federally marked navigational channel of the Cooper River in Charleston, South Carolina."

Other examples of allision, taken from the law reports, are a moving ship slamming into a bridge or rupturing or damaging a submarine cable.
