I have had this issue myself. I cannot get my first of the two ships i own to go out now, because, while it *shows* that there is a captain assigned, the voyages screen won't let me send out.
I even recruited yet another captain, so I have one without a ship, and still cannot get the ship to voyage. I imagine somehow an old bug must have been reinstated. (note: this only came up because I failed badly in a voyage and lost an experienced captain).
