Grand Theft Auto III/A Drop In The Ocean

Brief
Donald needs Claude to find a boat and collect six drug packages that will be dropped by a plane off Staunton Island into the water, before anyone else does.

Walkthrough
The actual collection of the packages is not timed and not difficult, but allowing the police to reach one first will result in mission failure. Each package will increase your wanted level (to a maximum of five stars, or four stars in Definitive Edition), so boats and choppers will be chasing you, and considerable law enforcement will be waiting for you on the shore.

When returning to Love, you can always loop around in the boat or try to find a different spot if there are too many FBI waiting near the shore initially, but you may need to brute force through them. You don't need to lose the wanted level before returning to Donald, so don't worry about a Pay 'n' Spray; just make a mad dash for his tower and you'll pass the mission once you enter the blue corona at the door.
