Sub rocking sideways
 
Hello,

I just noticed that my sub is rocking sideways, at 10 kts. Going at PD solves the problem. Sometimes the rocking is less I don't know if it has to do with any mod I've installed. Is this realistic or a bug? I got TMO 2.2 and some of Webster's MOds installed SH4 1.5.

Also st surface the Deck watch is there on the crew menu but now the sub has nobody on the deck....is my crew on strike???:dead:

The only time iv had my sub rock sideways is if a depth charge gets close and get rammed by a ship, other than those i dont know what else would cause the rocking, what mods do you have installed?

I've never tried to sail in a sub, so I dont know if its realistic, but its very realistic in a normal ship to follow the waves. Actually I think the subs are not rocking at all compared to the wavesizes, but I guess that has to do with gameplay rather than realism. (I've been diving a lot in the pacifics, and sometimes the waves throw the (somewhat smaller) diveboat around like its a toothpick in a blender ;)
Also some of the nightboats I've taken when I lived on Koh Tao (Thailand) was a fun (sometimes scary) experience, and those boats are around the size of a small sub (and keel-less).

Sometimes if you looked out the window you would only see the sea, then 5 sec later you would only see the sky. I guess since subs are keelless and slim, the wavesize and rocking would be even more drastic than is.

edit. and when the boat is in high waves, you wouldnt want to be on the deck. simply too dangerous.

Any ship on the surface is influenced by six separate directions of motion:

1. Roll: The ship rolls back and forth with lateral wave motion.

2. Pitch: The bow rises and falls as the ship encounters waves.

3: Yaw: The boat wobbles in its direction of travel as waves strike the bow or stern at odd angles.

4: Heave: Wave action can force the entire ship to rise and fall.

5: Surge: The entire ship can surge forward or aft due to rogue wave action.

6: Sway: The entire ship can be forced sideways.

Where it gets fun in bad weather is that opposite forces can come into play. The bow can pitch downwards as the whole ship rises while the ship sways to port as the bow yaws to starboard. Lots of fun. In a submerged submarine these forces are still in play, especially at shallow settings such as periscope depth.

Way hay and up she rises, early in the morning!

I noticed that in slower speeds the rocking tends to be subtle so I guess this is intended on the mod. I was just making sure that this rocking was a normal thing on the sub when surfaced.

Semi related, fun reading with two caveats:

Story's occur:
- On a Tench class, during the cold war
- In the Atlantic ocean.
