What is the best submarine simulation program for windows xp?

Dangerous Waters

I'm a Sub Sonarman, this game is a close as you can get without going to sea.

I actually used it when on shore duty to keep my Target Motion Analysis skills sharp in the Sonar part. The US Navy uses a very very similar program to do training with.

I have only played Silent Hunter III, it was a great game. Its was the first simulated game that I played on my PC.

I would check this link out it list about all the simulated Sub games out in the market. http://www.subsim.com/ and click on Reviews it will list all the games. Then click a selected game. then scroll down it will tell the overall rating of the game. Some will tell bugs and other information about the game.

Hope this help!
