Turn ratio

jakethescot · 02-23-16, 08:39 AM

I've searched for, but can't find, the turn ratios for ships. I can be within 2500m of a ship, have my torpedo speed set to fast and upon seeing the bubbles, the ship turns hard to port or starboard and the torpedo misses. My question is; did ships, even the larger cargo and merchants, in real life turn that tight and that fast?

Merchants not so much. A ship has a different set of problems than a car or a plane, and ships turn tighter the faster they go. At 30 knots an Iowa class battleship could actually out-turn a Fletcher class destroyer.

At the kind of speed a convoy is moving the ships should barely be able to turn at all.

Thanks, Steve. Can this be adjusted in game?

Yes, attack at night!

Or less lifting periscope also help... Usually when spoted me before I sunk

Either way, they turn too fast. Are there any files that can be adjusted so ships have the correct turn ratio?

There are or is a mod that fixes ship acceleration physics. Not sure if it does turning also. But I can't remember the name of it. Or what it is compatible to. And I may even be mixing up SH3 with SH4.

There is a mod for sh4 that changes ship physics to a more realistic level. Not sure if there is one for sh3.

For ships accelerating and decelerating you may use: THOMSEN PARAMETERS APP - by Stiebler

For turn ratio you need to work with the different drag coefficients in ships .sim files.

Thanks for all the replies. Looks like my best option is to not let them see me or the bubbles.

Pretty much any ship ever made can turn quick enough to get out of the way of a steam powered torpedo fired from nearly a mile and a half away (2500m = 1.42 miles )

The hard part about turning away from a torpedo a mile and a half out is seeing it in the first place, bubbles be damned!
