This page is a walkthrough for the Cayo Perico Heist Preparation Mission, Longfin. It’ll navigate you through the necessary steps to successfully acquiring the boat.
Go to Vinewood Police Station / Steal the Longfin
Once you’ve activated the mission via the planning board on the Submarine, either use the sub to fast travel closer to the Vinewood Police Station or simply drive there yourself. After you’ve arrived at your destination, wait a few seconds, then travel to the Trucks which are marked on your map.
Upon acquiring the trucks, return to Vinewood Police Station and take out the officers surrounding the Longfin, then hook up the boat to the truck. Finally, you’ll want to lose the cops by keeping off-road, then deliver the Longfin to the docks to bring this mission to a close.
