He would know a few things. Weight is always a factor, lightening the ships somehow (there is a massive hole in Cyre’s cargo hold). Sloane has lots of gizmos for the elemental on the Zarantyr. Wind doesn’t drive the ship, but a tailwind always helps.
In Gzizmix's exporatin/experimentation did he find any part of the ship that Cyre was able to move/control? Can she feel the entirety of the ship? Can she pilot the elemental? The child had a sorm mark so I assume she may learn to direct the elemental. As a warforged ship I would assume she was built for a purpose. The only advantage of making the ship a warforgs would be to make it self repair (does not seem to be the case), self motivated, or what?
