The NR-1 Undersea Research Submarine by Mike Hense
-------------------------------

Features:
-------------------------------
- Realistically modelled exterior.
- Fully modelled interior with 'sense of reality' construction techniques that allow movement within the confines of the model while preserving the illusion of being inside a real submarine. In short, there are no breaks in the model to ruin the virtual experience.
- External views of the undersea environment is made possible by simulating TV monitors connected to external cameras on the sub. There's nothing more boring than being stuffed in a tube with no way to see out... now you can.
-  Translucent, nearly transparent materials on see through surfaces.
- Movable control surfaces. The fairwater dive planes and the rudder move in response to the sub pilot's control inputs.
- Retractable external manipulator arm and landing gear. Yes, the real NR-1 has both, and I've added them to the model. Use the Main Sail control keys (PAGE UP/PAGE DN) and the Jib Sail control keys (INSERT/DEL) to extend and retract them. 
- Realistic engine and dive alarm sounds taken from real Naval ship operations.

Installation:
-------------------------------
Simply unzip all files into the main VS folder. Be sure to check the 'use folders' checkbox!

Usage:
-------------------------------
Movement Inside The Sub:
Select NUM LOCK ON to enable the numeric keypad number lock. Use the keys on the numeric keypad to move about the interior of the submarine.

First Step, Get in the Pilot's Seat:
To start out, press F1 to place you at the helm station.

To Move Aft to the Ladder:
Press KEYPAD 3(pgdn)  three times, followed by KEYPAD PERIOD (del) key three times. This will place you at standing height at the centerline of the sub. Then press the KEYPAD 6 (right arow) to rotate around so that you are facing aft. Press the KEYPAD 7 (home) key to move aft. Stop near the ladder.

To Go Up To The Bridge:
Press the KEYPAD 5 key to face forward then use the KEYPAD 6,8,2 and 4 (arrow) keys as required to position you close and just to the left of the ladder. Then press the KEYPAD PERIOD (del) key to climb up the ladder to the bridge. 

Look Around:
Use the KEYPAD 4 and 6 (left and right arrow) keys to rotate around to scan the horizon. You can adjust your fore and aft position on the bridge with the KEYPAD 8 and 2 keys.

Going Back Down Into The Sub:
Always face forward and align yourself near and to the left of the ladder (two metal nubs sticking up on the right side of the bridge) before decending back into the sub. This will allow you to move while avoiding looking through a bulkhead structure and help maintain the 'sense of reality'.

Before Diving Checklist:
- Take the Pilot's seat (F1 key).
- Turn on AUTO SAIL (G key).

Dive!!! Dive!!!
- F8 key to sound the dive alarm.
- F9 to commence the dive.
- Press the G key to release AUTO SAIL and use the ARROW KEYS to control your dive angle. I usually keep 3 to 4 degrees until past 30 feet, then increase as required after that.

Level Off and begin exploration...

Information:
-------------------------------
The virtual version of the NR-1 Undersea Research Submarine is based on the real NR-1 which is operated by the U.S. Navy, and is used primarily for deep sea research and recovery. While I have endeavored to recreate all aspects of the real thing, anyone familiar with the real NR-1 will find that there are a few small differences between the real NR-1 and the Virtual Sailor© version,  none which will detract from the impression of actually taking a high tech undersea research vessel to the depths of the Virtual Sailor© environment.

The NR-1 model is big, lots of polygons... sorry, I did the best I could while trying to make the thing look sorta realistic. This may cause Virtual Sailor to take a little bit more time to start up. 

Also, network play may bog down abit on slower machines, especially if you are the server, and are connecting via a slow network.

The NR-1 has been tested on a 266 mHz PC with a 4 MB 3D video card running Virtual Sailor©  with acceptable results.
Recommended minimum platform is a 450 mHz PC with an 8MB 3D video card.
You will sail happily with a 733 mHz PC and a 32MB 3D video card.

Personal:

I hope you enjoy sailing around the NR-1. If you really like submarines, and undersea navigation, then you know where I'm coming from building this model.
Enjoy....
