Baddeck is a buoy boat who brings new buoys into the harbour.
Another time Bedford Buoy almost left the harbour with Baddeck, as he was feeling left out.
He is based on the buoy tender ships operated by the Canadian Coast Guard.
In the fourth season, Baddeck's hull was painted green. But in the fifth season, Baddeck's hull was painted white.
