The gross tonnage figure of 100 cubic feet might actually represent the space required for a "tun cask of beer".  Remember that these figures come from somewhere and practical history is often the source..  The two information sources may not be in conflict after all.

Well, not quite, at least not directly or today.  From World Book
Encyclopedia, 1988 edition, vol. S, p. 416:

"Deadweight tonnage is a ship's actual carrying capacity measured in long
tons. ... includes cargo, crew, passengers, fuel, supplies and spare parts.
Freighters and tankers arte generally described in terms of deadweight
tonnage."

It also describes two other measurements of tonnage, displacement tonnage,
"the number of long tons displaced ... by a ship ... is generally used for
naval craft," and gross tonnage, "the amount of a ship's enclosed space.
It is a measure of volume, not weight, and is expressed in units of 100
cubic feet ... .  A ship of 5000 gross tons has 500,000 cubic feet ... of
enclosed space.  Passenger ships are usually measured in terms of gross
tonnage."
