I watched from the outer breakwater, the same two Iceland Gull's (Juv & Adult) follow the trawlers into the Bay. The first I picked up at 1545 which was the Juv. It did enter the harbour for a spell. The Adult appeared 1615 following another trawler and stayed, as Mike had said, behind the trawler as it was gutting outside the harbour wall.
Also 10 Purple Sandpipers along outer harbour wall.
