Nice work.

The numbers for crash speed are probably accurate, but the depth is who knows what - furlongs per fortnight or something other than meters, whatever

I tried setting the crash depth above 300 to get ships to stop sinking in heavy seas, to no avail. The various zones might have their own crash depths, though. Also, I don't know if the crash depth is related to the bottom, top, or middle of the zone.

I think your theory, about them taking shortcuts on the model, is on target.
