Bollard- A single post or upright fitting used to secure a mooring line. Bollards are usually found on docks, piers, or wharves.
Bollard Pull- A measure of a tug's pulling power. It is usually measured in tons by securing the tug to a scale. The tug then pulls against the scale and its bollard pull in tons is recorded. Bollard pull is determined by a combination of the tug's horse power and the type of propellers that it uses.
Bulwarks- The side plating that forms the railing around a tug's main deck. Also, it is commonly called the waist.
Eyebrow- A pet name for the visor. (Which see.)

Hogging line- Like a gob line (which see), a hogging line is a piece of long line attached to a towing cable and run to a capstan, pulling down on the cable with great force and keeping it secure in the center of the stern while underway.
Romsey- A British tug that quite possibly carried the infamous Lee Harvey Oswald from his cruise ship to shore during a trip to Europe in the early 1960's.
Tasman Sea- The Tasman Sea is the large body of water between Australia and New Zealand and is a south-western segment of the South Pacific Ocean. The sea was named after the Dutch explorer Abel Janszoon Tasman, discoverer of New Zealand and Tasmania. The British explorer Captain James Cook later extensively explored the Tasman Sea in the 1770s as part of his first voyage of discovery. There is a tugboat named after this sea and is owned by K-Sea Towing in the United States.

Visor- The band of metal over the wind screens of the pilot house (wheelhouse) that shade the skipper's eyes from sun. Sometimes they are painted green underneath. This reduces the glare from the sun reflected on the water without darkening the interior of the pilot house.
Waist- The plating around the main deck of a tug that forms the railing. See also Bulwarks.
