The Chum Guzzler is a small boat chartered by Nikolai Jakov for a vacation with Malory Archer in the episode, "Skorpio." The deck had plenty of room for a barbecue and other vacation activities.
It was destroyed when the massive propellor, from Spirodon Skorpio's mega-yacht, landed on it after the yacht exploded.
This ship's name is also likely a pun to "Cum Guzzler" as Jakov's name is also a pun to "jack off"
