Sailing the PBR.
You can start your "flight" anywhere you wish, then simply slew to some water.
For best effect, enable Auto Rudder, and put your feet on the floor.
Before moving out, deploy your water jets for steering.
The real PBR had a top speed of about 25-35 knots, but I gave some extra speed for the fun of it. You can top out at quite a high speed. Also, I've never before made a "seafile" :)
The front turret guns will elevate and traverse with stick inputs.
The PBR is equipped with a smokescreen system. But it's kind of lame in FS02.

Boat to FS equivilents:
Searchlights = Landing Lights
Nav Lights = Nav Lights
Mast Beacon = Beacons
Panel Light = Panel Lights
Smokescreen = Smoke System
Waterjet Deploy = Water Rudder Deploy
