Colchester is a container ship Theodore and Emily helped bring into the harbour when Hank was suffering from hiccoughs. He also appeared during Theodore's Birthday party and when Theodore had his backwards problems. He is a big, bold green-hulled container ship from the United States of America, and is easily one of the biggest ships ever to tread water in the Big Harbour.


  • Colchester apparently uses the same model as Cumberland.
  • Colchester's model was sold on eBay, but his hull was painted in Canso Colossus's colours!
  • Colchester's hull was used for Canso Colossus's hull.
