I'm working on designing a new ship for Chile, and I'm annoyed by a small issue which I'm often faced with, but rarely have a solution. For the vessel I'm creating, I can get a steadiness of 70, which Springsharp tells me is desirable; but that means stability is 1.05. For various reasons I like stability to stick right around 1.10, but that lowers steadiness to 62.

So, I ask you: which is more desirable in a vessel, particularly one built for the seas near Cape Horn? Stability, or steadiness? I'm under the impression that stability affects how your ship handles things like counterflooding following torpedo hits; therefore I tend to make my stability high in order to make them survive more hits.

For that matter, can someone define the difference between stability and steadiness?

Stability is a measure of the ship's ability to right itself after a roll.

Steadiness is the measure of the period of the roll.

So, for designing a cruiser, which should I favor? What should I favor for a DD or CV? I'd guess that a CV would need to be steady for launching aircraft, but you'd maybe want more stability from a destroyer which is wallowing about in the same sea...?

Well being a gun platform you'll want a slower roll rate for a cruiser or battleship.

Hmm, so... in my particular case, a stability of 1.15 and a roll period of 16.2 seconds will suffice?

It's more than just that, seaboat quality comes into it as well.

Note the "Magni" specs below....

Stability (Unstable if below 1.00): 1.12
Roll period: 17.9 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.04
Seaboat quality (Average = 1.00): 1.56

Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather

So just the Steadiness V Stability thing doesn't work, seakeeping needs to be included

It's 1.60 seaboat rating.

Well then she should be just fine!!

EDIT - What is her steadiness?

With a brief reworking, I have:

Stability: 1.13
Steadiness: 71
Seakeeping: 1.60
Roll period: 16.3 seconds

Seems very good to me.

I think I know what type of vessel this is

Sweet!!
