rendering: water clipping in ghost players

[jamesfarrell97]

The Issue:
Water appears to clip through 'ghosted' boats.

The Expected Functionality:
Water should be masked in ghosted boats (i.e. water should not be rendered within the bounds of the boat model). This is to create the effect that a boat is floating in the water.

Steps to Recreate Issue:

1. Start or join a multiplayer game
2. Observe other networked/ghost players
