The Pontoon Dock was situated at the top of Point Law, Albert Quay along with Dock No. 2. It was used mainly to lift the trawlers out of the water to get the bottoms cleaned and repainted and other underwater tasks entailed in the early days before power washers.
When the pontoon was lifting the trawler out of the water 2 squads of men in 2 punts would scrub the hull with hard bristle sweeping brushes to get rid of the barnacles and mussels attached to the hull. The pontoon worked by opening valves to let the water into the tanks to sink the pontoon. Once the pontoon was sunk and vessel positioned in place the water was pumped out and the pontoon and vessel came out of the water.
The pontoon was broken up at Dales Drydock in the early 2000s? when Albert Quay was being refurbished and the fishing industry was in decline and was no longer needed.
