The tramp steamer was first seen at Knapford Harbour in the third and fourth seasons, and was later shifted to Brendam in the fifth season. She was also seen bringing special loads of fruit to Arlesburgh Harbour.
It is currently unknown where the tramp steamer/Izzy Gomez's model is.
The Old Tramp Steamer
The old tramp steamer only appeared in the fifth season.
During her first appearance, she lost control and ran aground and crashed into a shed the engines were in at Brendam, causing it to collapse and knock Cranky over. The tramp steamer also brought the horrid lorries, and special funfair equipment to Brendam in its later appearances.
The Captain's Ship
In the seventh season episode, Salty's Stormy Tale, the captain's ship was sailing back to Brendam Docks at night. Unfortunately, the lighthouse's lamp had gone out, and the generator was broken. Without the lighthouse, the ship was steaming toward the rocks. Luckily, Fergus' flywheel was used to power up the lighthouse's light and the tramp steamer missed the rocks just in time. In the morning, the captain thanked Salty and Fergus for saving his tramp steamer from capsizing.
The captain's ship first appeared in the seventh season, and she has made several appearances since.
