Tug Boat
The Tug Boat is a very large and very slow boat in GTA IV. It can usually be found near the barges in the Humboldt River between the Broker and Algonquin bridges.
Whilst on the Tug Boat, your character cannot run. However pressing the correct button to board the ship will also cause your character to automatically walk to the wheel of the boat wherever you are on the boat. As this vehicle can only properly contain one person in multiplayer (the driver), others can still stand on the deck, however all other characters will lose some control of thier characters making it really hard for them to move.
When the boat is moving, any other character on the boat will also begin to glide off slowly, and if you are stood at the front of the boat you can actually pass through the built up area of the boat and see the water beneath it.
When in the water, you can board the ship by pressing jump and the character will do a giant leap for the side.
