Design and description

According to the Miramar Ship Index Whitefish Bay has a gross tonnage (GT) of 24,430 and a deadweight tonnage (DWT) of 37,690 tons. [3] However, on the CSL website, the ship is stated as measuring 24,430 GT and 34,500 DWT. [4]

Thunder Bay is 225.5 metres (739 ft 10 in) long overall with a beam of 23.76 metres (77 ft 11 in). [3] Thunder Bay has a maximum draught of 9 metres (29 ft 6 in). The ship is powered by one IMO Tier III MAN B&W 6S50ME diesel engine driving one shaft creating 8,750 kilowatt s (11,730  hp ). [5]

The ship is equipped with five holds and has a net hold capacity of 41,917.96 cubic metres (1,480,319 cu ft). The vessel has an average unloading rate of 5,450 tonnes (5,360 long tons; 6,010 short tons) per hour. [4] CSL asserts that the new vessels will be more efficient than existing vessels, and will leave less pollution. [6]
