Captain Wreckless,
If you want some play pointers, I highly recommend going to Captain Jive Turkey's youtube page (
https://www.youtube.com/channel/UC9b...NaMPsK9GtzM5dQ). Jive was a sonarman/sonar supervisor on 688 boats for 20 year. He streams on twitch, youtube, and mixer, and has a very loyal following online and is entertaining.
I ended up buying the game a couple of months ago, after watching some of his past streams. (he has nearly 300).
