I would actually say both 1 and 2. Basically, the spirit of the card (see what I did there?) seems to be that[o](a) the ship can stay in its space, regardless of the presence of another ship
(b) it's legal for other ships to move into its space
(c) if it moves, it must move in such a way that it doesn't share a space with any other ship throughout its move
So it appears to be legal to move the haunted ship, then move your other ship to the same space separately. If you did so (or if you simply didn't move), then the haunted ship couldn't support the other ship, but the other ship *could* support the haunted ship.
Note that I don't have the card in front of me, so I'm assuming you've quoted it correctly. :)[/o]
