Captain Chester (French: Capitaine Chester) is a gruff merchant skipper and an old friend of Captain Haddock.
He first appears in The Shooting Star in Iceland, where he is ordered to bump into Captain Haddock at the docks and launches into a bizarre greeting ritual with Haddock which Tintin at first interprets to be the build-up to a fight. However, Haddock and Chester warmly clasp hands and take Tintin to a local bar to reminisce over a bottle of whisky. Chester is captain of the Sirius, a merchant trawler, and uses it to secretly refuel Haddock's research vessel in Iceland when their competitors block the supply, allowing the captain's ship to siphon fuel from his tanks while it is pumped in. He is briefly mentioned in The Secret of the Unicorn. Chester later lends the Sirius to Haddock when he and Tintin set off to find Red Rackham's Treasure. Chester is briefly mentioned in The Seven Crystal Balls when Tintin and Haddock attempt to visit him while he is docked at a port, but he departs before they arrive. He is also one of the people who sends Haddock a concratulatory telegram in The Castafiore Emerald.
