All at Sea is the eighteenth episode ever made in Season 3.
Duck and Percy are working at Brendam. Duck often sees boats around the harbour, and when a regatta is held in the bay, Duck starts wishing he could travel on a boat, despite Percy and Harold's comments. Then one day, a man injures himself on a boat. Harold brings him ashore and Duck quickly races over to the yard, where Bertie rushes him to the hospital. The same night, Duck and Percy stay longer at the quay, when Harold drops a flag from the regatta for Duck. Nowadays, Duck dreams about traveling to the horizon, but appreciates that engines need rails.
- When Duck reverses from the level crossing, he leaves his driver behind.
