I'm not sure what they are worth. They've been collecting dust in a chest. 1000 gold a piece?How much for them?
You are correct. I must've been thinking of the Gargoyle ship.From what I'm reading the Gargoyle ship can be purchased from a shipwright. The Orc ship is acquired by by completing a quest for parts and then turning them in as a whole.
