Wanna drive a specific boat of a class?

Let's say you start a new campaign and are a Clancy-scrub like me who really really needs to command the USS Dallas, Bremerton or other boats from his novels.

Go to:
Steam\steamapps\common\Cold Waters\ColdWaters_Data\StreamingAssets\default\lan guage_en\vessel\

Find:
usn_ssn_los_angeles_description.txt

Back it up and then edit:
[Player Ship Instances]
PlayerClassNames=Los Angeles, Baton Rouge, Philadelphia, Memphis, Omaha, Cincinatti, Groton, Birmingham, New York City, Indianapolis, Bremerton, Jacksonville, Dallas, La Jolla, Phoenix, Boston, Baltimore, City of Corpus Christi, Albuquerque, Portsmouth, Minneapolis-Saint Paul, Hyman G. Rickover, Augusta, San Francisco, Atlanta, Houston, Norfolk, Buffalo, Salt Lake City, Olympia, Honolulu

PlayerClassHullNumbers=SSN-688,SSN-689,SSN-690,SSN-691,SSN-692,SSN-693,SSN-694,SSN-695,SSN-696,SSN-697,SSN-698,SSN-699,SSN-700,SSN-701,SSN-702,SSN-703,SSN-704,SSN-705,SSN-706,SSN-707,SSN-708,SSN-709,SSN-710,SSN-711,SSN-712,SSN-713,SSN-714,SSN-715,SSN-716,SSN-717,SSN-718

To (for example):
[Player Ship Instances]
PlayerClassNames=Dallas

PlayerClassHullNumbers=SSN-700


Now, whenever you start a new campaign with the Los Angeles-class, only the Dallas - or whatever you enter there - will be assigned to you.
