I don't think this is supported by "Masts sprout from every deck, a 
hundred times taller than the Flag kepp of the Citadel," or by Severian 
being able to leap clear the distance from the deck to the startop 
wihtin a few minutes of indulging himself. (At least, he does not remark 
on the passage of time or become concerned over needing to eat or drink.)

A straight line with a sudden veer require the removal of gravity and 
inertia from the picture. Not that the Yesodis can't do that if they 
need to, but why bother with sails at all if you can do that?
