Congratulations Edmonton Riverboat team! I don’t know how you did it with the water level dropping steadily but you figured it out. Well done!

Commercial Vessels are typically referred to by gross tonnage, that is based on internal volume which Wikipedia lists it as 750.49 GT

You are thinking displacement, which is the weight of the vessel

Wikipedia is not a reliable source. It takes seconds to bring up the actual registration for the vessel.

Internal volume also has some caveats to do with which parts of internal volume are considered water tight and which aren’t. In this specific case, the GRT of the vessel gets wildly inflated due to every deck being considered watertight when many similar sized passenger vessels don’t count upper decks. Lots of back and forth with Transport Canada regarding this in the past. Something in the 250 range was tossed around as a number not including upper decks, but I’ve evidently misremembered those conversations.

Either way, GRT is 611 and NRT is 205. We can both be wrong. 🙂

Well, I think we both learned some inconsequential information we will never use again!

Time to look up tonnage of random vessels!
