Cheliax, like every major nation on the Inner Sea, has an extensive number of merchants ship, fishing ships, and sailors to operate them.  Unlike many other nations though, Cheliax has extensive measures to stop potential defectors.  Every ship's captain and ship's wizard was subject to regular detect thoughts.  Every ship above a certain size was required to carry a cleric of Asmodeus, who in addition to providing a supply of drinking water and healing would also serve to keep an eye out for illegal activity.  Any incident of stowaways would be dealt with harshly and any captain, ship's wizard, or ship's cleric abetting efforts to smuggle a person would be put to death.  The crew itself was subject to a detailed record of all it's members including a listing of names, locations of origin, and family members (to suffer the consequences should any sailor happen to wander off in a foreign port).
