- "I think my partner's a rat! We gotta shut him up, permanently! He goes fishing out of his boat near the lighthouse on Portland Rock most nights. Steal a police boat and make sure his backstabbing plans are sunk!"
- ― Ray Machowski
Machowski tells Claude that he thinks his partner is a rat so he wants him eliminated. He instructs Claude to drive a Predator in Callahan Point over to Portland Rock where his partner is usually seen fishing. As Claude arrives, he finds that Machowski's partner is in a boat containing explosive barrels, fishing the "redneck way" by throwing grenades into the water and killing dozens of fish at once. The partner spots Claude and attempts to flee from him.
After being chased for a short period of time around Portland Harbor and dropping all of his explosive barrels in an effort to stop Claude, the partner beaches himself and the boat and begins to run on shore near the Supa Save! supermarket. Claude beaches himself as well and guns him down, completing the mission.
In order to complete the mission the player must:
Occasionally a glitch occurs where Ray's partner blows himself up with a grenade during the fishing cutscene, thus automatically completing the mission.
- Ray Machowski's Partner - Killed on orders from Ray Machowski for being a traitor.
- The radar will show a Predator made available by Ray in Portland, but it's not mandatory to take that one. Any Police Predator will do.
- Machowski's partner's boat is a special unique boat that cannot be found anywhere else in the game. The boat's default color is "police car blue" in the PS2 & mobile versions; however, it is spawned in a unique black color in the PC & Xbox versions.
