13b. There is a quarry mentioned in the prologue to Martin the Warrior.

3. Just because there really wern't that many corsairs with ship building skills mentioned, dosen't mean there wern't any. In Pearls of Lutra, the corsair leader-whose-name-I-cannot-remember wanted Ublaz to give him lumber to repair his ships. That implies that he had people who knew how to repair the ship. There haven't been, as far as I know, any books where ships are actually constructed. So it really isn't important in the story for it to explain how or where the ship was built.

8. What is there to pollute it? There are shrimp in the pond that the fish could eat.
