It’s called a dolphin

Our waterfront contains two sets of steel pilings each capped by a concrete structure that sits apart from the pier and above the water line.

In Eastport’s case, these are mooring dolphins, where lines from a ship exceeding the Breakwater’s 400-foot dock length can be attached to help secure the vessel in port.

Here’s one in action.

The line’s slack now but won’t be when the tide rises more.
