Historical Realism Patch

The main purpose of this patch is to correct some historical inaccuracies in Silent Hunter. It gives all of the S-class boats their historical hull numbers, modifies the layout and/or performance of some classes of subs to reflect historical wartime specifications, and corrects a few annoying little things in the game like engaging the enemy in a surface gun action while cruising along at 35-foot keel depth. It will also allow you to mount the deck gun forward on the deck of those fleet-class subs that have them mounted aft. It gives the player five options to implement in the game. You may select any or all of the options to install, or choose to restore all options to their original factory settings.

Merchant Ship Patch

This program changes the dimensions of the merchant ships in Silent Hunter to make the sizes of the merchant ships you encounter in the game variable and perhaps more realistic. The warships in the game are NOT affected at all by this patch, it only modifies the length, beam, draft, and displacement of the merchant ships. It does NOT alter any of the ships' actual appearance, so a 9000-ton tanker will look exactly like a 16,000-ton tanker in the game. However, the changes this patch make ARE reflected in the Ship ID Book, so you can see what each vessel's dimensions are after you run the program. You can use this program in conjunction with the batch file SILENT.BAT included in the package to automatically change the merchant ships' dimensions each time you start the game.

Edit Rank Utility

This small utility modifies the default rank of Commander for Silent Hunter skippers. This new version allows you to select either Lieutenant, Lt. Commander, Commander, or Captain as the rank. Historically, most submarine CO's were Lt. Commanders or Commanders but there were a few exceptions. The rank of Lieutenant was added because many of the S-boats at Manila in the beginning of the war had commanding officers who were Lieutenants.

Campaign Boat Selector

This program is a save game editor for Silent Hunter. It allows you to change the individual submarine you've been assigned in your career campaigns. Each submarine's availability is limited by the date during the war when the game was saved. In other words, you can't go patrolling around Luzon in January 1942 in a TENCH class sub. The S-Class boats represented in NEWBOAT all have their historical hull number designations instead of the ones used in Silent Hunter. For example, the S-36 is given its historical hull number (SS-141) instead of the one it's given in Silent Hunter (SS-36). NEWBOAT also makes a distinction between the SALMON and SARGO class submarines. NEWBOAT will also allow you to change the name of the commander. NEWBOAT only supports career campaign games saved while IN PORT. This means that once you select a different boat and go out on a patrol, you're stuck with it until you return to port.

Kim Ronhof's Manual Tools With Guide

The key to success in any warfare is to know more about your enemy than he does about you! In submarine warfare this is achieved by being able to remain submerged and thereby stalking the target. To do this successfully you have to anticipate the target's next move. Plotting the target and thereby calculating the target's speed and course is the only way to achieve this.

With this information an attack plan can evolve, and hopefully a successful attack can take place.

The key to it all is Radar Plotting!

With accurate Radar Plotting, attacks can be successful even if you never even see your target!

This manual will take you through the different steps in making a successful attack using some simple tools that make any sub-skippers life a real joy.

The included tools are the Radar Plotting Device, the Course Calculator, the Range Calculator, the Sonar Bearing Plotter, and the Manual TDC.

Kim Ronhof's Torpedo Change Tool AKA Kim's Multi Purpose Tool Version 1.6.0.0

This tool lets you change Silent Hunter data files. It includes a New Maru Function which is similar to Hawk's Merchant Ship Patch.

It is fairly simple to use and will work in Windows Vista. Just read the documentation and follow the user-friendly menu system.

You can change the following data:

The patrol area.
The submarine type and name.
The Salmon/Sargo Class submarine specifications. See warning note on use!!
The deck gun position (fore or aft), but only on fleet submarines.
The crew experience level.
The torpedo load (type of torpedoes, and distribution into tubes and racks).
You can reload fuel and ammo for the gun.
The departure date.
The tonnage, length, beam and draft of the nine Maru types found in Silent Hunter.

But not all can be done at once; it depends on your patrol status (in harbor or on patrol).

The newest version is labeled Torpedo Change Tool Version 1.6.0.0. It has the added haze button to help correct the "disappearing fog" problem when you save a game and restart it. A glitch in the program will make the fog disappear and you may get caught on the surface by the enemy. This new version will help correct that by letting you load the last roster file that the fog was occurring in and thus help keep you from getting attacked because of the disappearing fog effect.

Kim Ronhof's Patrol Report Data Tool (PRDT)

The patrol report data tool can extract data from a Silent Hunter career file.

It can only extract data from a career in harbor.

What do you do?

1. Play the game as usual. When it's over and you've reached the harbor, Silent Hunter generates a report. Some of the data from this report is saved in your career file. It's this data that the program lays its greedy hands on.

2. Use the PRDT to extract this data, from the last patrol (and the only patrol in the career ).

3. Copy the data that the program extracted to the clipboard, then paste it into a word processor of your choice.
