Via Ocean Mostali Induced Trauma:
Despite their high CON and immunity to illness I believe that the Mostali
perceptive sense (Earthsense) would be so disorienting in on a normal ship
that they would be dizzy, giddy and probably Grumpy (possibly Sneezy and
Dopey). Their concrete ships would be less upsetting but just becasue they
have ships does not prove that they don't get seasick. Humans have ships.
As a test I propose capturing a dwarf, and forcing him to spend several months
at sea in a little wooden boat, and then seeing if he like it.
