Captain Cod asks Davy to be careful moving cannonballs about, but poor Davy ignores him and ends up dropping a heavy cannonball through a hatch where it goes right through the keel causing a leak. Davy is so embarrassed he shuts the hatch and goes to bed. The next morning, he wakes up to find the bottom of the boat is full of water. He decides it's time he owns up and bravely goes to see the captain. But will it be too late to save the ship? Will Davy get into trouble for not be honest in the first place?
