Red Rackham's Treasure - S1-E5
Continuity mistake: In the very first shot of the Sirius, the anchor is about 10 foot away from the Sirius sign and not yet released into the water. When the boat leaves the docks, the anchor is now a mere foot away from the Sirius sign and the anchor is now retracting from the water even though it wasn't even in the water a minute ago.
