The calculation for altitude for screwgalleys seems completely off in the Sky Galleons of Mars and the Cloudships and Gunboats supplements.

Each turncrank position, equal to the number of turncrank men I figure, is 10 tons. So the Skyrunner from "Cloudships and Gunboats" expansion has 16 turncranks = 160 tons.

The ship itself is a 300 ton rated vessel.

To figure out the max altitude, you divide that 300 by the total weight of the ship's components that go into the calculation:

160 tons for the turncrank positions

About 120 for the armament: 2 heavy guns (40ea) and a rogue gun (60)

That's 180 tons; so 300 / 300 = 1

Problem is, a quotient of 1 means only a max of 'High' altitude. But the listed max for the Skyrunner is 'Very High', the highest possible.

Other screwgalleys have this same issue in their calculation compared to the listed altitude rating.

What the heck am I missing here?
