I liked the baskets up around the tree for the crow's nest. There was also a wooden wheel for the mates to turn and a large clock on the bow. At the stern was a detachable flag that could be taken out and waved at their capture r (parents) as they sailed away for a small reprieve. Luckily no plank was visible as I am sure some would have been forced to walk into arms of land lovers below.
The kitty justice is the mates should have had to read the book before they were allowed to board the ship.
