The tonnage which I have set for the Chatham is currently about 5,500 GRT. That was about the tonnage of the actual ship on which it was based.
The hull is a modified C2 hull, so it approximately that size.
The Nipiwan Park is about 2,400 GRT.
The other two ships which I might have done soon are the Belize Coastal Merchant and Heavy Merchant - the tonnages of those ships are around 2,300 and 4,500 GRT. There is also the possibility of the Caribou being finished in the next month - the tonnage of that model is 2,222 GRT.
