The "Nightlife Leak: The Marina" mission is the second stage in the Nightlife Leak chain from GTA Online’s The Contract DLC. It tasks players with investigating a data leak linked to stolen information hidden on a yacht near Puerto Del Sol Marina GTA 5 Accounts.

Players begin by heading to Puerto Del Sol Marina, where they must locate and steal a distinctive green speedboat parked along the marina’s left side. Once aboard, the player races out into the ocean to avoid immediate enemy fire. The map then reveals a large yellow search area indicating the location of the target yacht.

Players can approach the yacht stealthily, using silenced weapons to quietly eliminate guards before a full firefight erupts. However, stealth is optional, and combat is often inevitable. Upon reaching the yacht, players board from the rear, clear out enemies on multiple floors, and proceed to the bridge on the top deck.

At the bridge, players must defeat a guard and then interact with a control panel on the left side of the cockpit to unlock the main cabin door. After unlocking, they return downstairs and enter the main cabin area.
 
Inside the main cabin, players search for and photograph the evidence, which appears on a glass table and can vary in location each playthrough. Once the evidence is secured, players must fight their way back out, facing more guards on the way out buy GTA 5 Accounts. The mission concludes with an escape by boat or jet ski back to safety. Notably, dying during the escape does not fail the mission, as the objective is considered complete once the evidence is collected.
