Question

Ghoastley galleon what it mean

Answer 1

The moon was a ghostly galleon tossed upon cloudy seas, The next big metaphor compares the moon to a "ghostly galleon." A galleon is a big old ship, the kind that would have carried Spanish gold across the seas. So the moon is like a ship sailing through the sky.

Answer 2

The Ghostly Galleon is an old wooden ship that sank many centuries ago, and became frozen up inside an iceberg. The White Fleet were looking for this vessel during the winter where thick fog came down at night. Because of the warm water out at sea, the iceberg melted, causing the Galleon to rise to the surface, much to the surprise of Ten Cents and Sunshine. At the end of Ghosts, Burke and Blair are seen towing away the Ghostly Galleon to The Breaker's Yard.

The vessel has made occasional cameos in other episodes other than Ghosts. 

Good Luck :D
