Boat #4 was purchased in 1994 as the Patrol continued its quest to make its fleet as versatile and practical as possible. A national search led to this find in Fort Lauderdale, Florida. This rare model combined the strength and durability Black Fin is known for with an open hull design allowing for ease of movement bow to stern for Patrol work. A large cuddy cabin provides ample storage space for the increasing amount of rescue and assistance gear carried by the Patrol.

Despite being the largest of the Patrol boats, Boat #4 is very maneuverable and very stable in the water. A true ocean-going craft, this boat is the one in the fleet most able to handle whatever Geneva Lake throws at it. Boat #4 has earned the nickname "beast" for its ability to go out in the toughest of conditions, handling waves 5 to 6 feet high with ease.
