The comments regarding vessel handling in your simulator. I have no idea whom to send these, but I hope that game developers will read below and take this in mind for patches/further development.
I am merchant Ship Master for nine years and have tanker experience more than twenty years. The friend of mine shown me your game. I was really excited with job you've done and realistic environment I've met. Just to improve the game in next patches please be note the follows (I've tried free roaming of tanker only):
1. Max engine RPM should be within 100 RPM limit, not 500. In reality, all big tonnage vesselss have low revolutions engines to save fuel. However, ship movement in game is realistic. Probably, just propeller torgue moment is to be adjusted in physics game engine.
2. Basically, all cargo ships have single engine, not twin, same for above. There should be only single engine control unit in this case. Understanding, that it is game interface, I hope you'll be able to take it in mind for the patch.
3. The rudder in game is definitely working in vacuum space, not in the water. There should be water reaction to rudder turn. IMO SOLAS Convention (Safety of Life at Sea for non-seafarers) required that board-to-board time of rudder movement should be no more than 28 seconds. In fact, rudder movement from midship to board position is about thirteen seconds.
4. On real vessels there is possibility to remain vessel's rudder in any position you stopped it (for instance, 5, 15 or 20 degrees). It is understood that the game is designed for non-seafarers, but I suppose that there should be an option in game controls not to reset rudder angle to zero upon key depressed for advanced gamers.
5. Max rudder angle should not exceed 35 degrees (not 45 as in game). Really, the rudder do not turn above 30 degs as there is danger of its breakage, especially on big tonnage vessels.
6. I've not found autopilot on/off option in the game. It's widely used in real navigation practice.
Anyway, I'm glad to thank the developers for job done and ready to buy your game here in Russia upon official release. I hope my observations will be useful. Sorry for my English, I'm have the experience in Merchant Marine business only.
Hope to revert with other advises, if they needed.
Thanks,
