Rebuilt AC3 - Ceyhan & Canakkale

[Jefgte]

When I look at my armored cruisers, I see that they are all going at 27kts. But not for:
- AC2 Bourgas & Bapha (24kts) assigned to the 6th and 7th Colonial Battle Division (22kts).
- AC3 Ceyhan - Canakkale => 25kts commissioned in 1908.
So, I have 4 possibilities
1- Increase speed to 27kts.
2- Keep 25kts but increase armors to convert them into colonial battleships (vs 11 "& 12" guns) & surplus of the battle line.
3- Increase speed to 27kts and increase armors...
4- Do nothing and use the budget differently.

=> In any case, the armament does not change; 4T2x254 + 8x152

What is the refit date?

[The Rock Doctor]

25 knots is not terrible, and I don't know that you can increase it by more than about a half-knot before the seakeeping dips below 1.00.

Think I'd leave this class alone.

[Kaiser Kirk]

I'm not going to examine it closely, because I'm tinkering with rebuilds and shouldn't "peek" at Jefgte's plans.

I've been struggling with the seakeeping as well.
Is the extra speed in a rebuild OK if it results in poor seakeeping?

Functionally, Poor seakeeping should matter in bad weather with high sea states.
As ranges increase, I mean to take 'slow and steady roll' into account in rough seas as well.

So, say an old ship can make 30 knots refitted, but at 0.8 seakeeping.
But at 1.0 seakeeping it can only make 27knots.
In rough weather it would limited to the top speed of 27 knots.
While an equivalent vessel with a raised forecastle manages 30knots...
and so can dictate the terms of engagement - in that battle.

Of course, in rough weather, visibility will likely be down, so the chance of encounter is less,
and that encounter may start withing gun range - average expected ranges in the North Sea were ~12km.
Nighttime is the same.

The extra engine mass "costs" quite a bit.
The extra speed is not useful in rough weather.

But the extra speed may allow the ship to counter more modern vessels much of the time.
Is the extra speed worth it at the cost of poor seakeeping?

I'm leaning towards Poor Seakeeping being OK,
if it means most of the time you can manage a "useful" speed level for your fleet.

So far in wars, people have been fighting in good weather.
There were some unseaworthy (<0.75) DDs caught in a hurricane and some sunk.

There were MTB and Landing operations delayed for lower sea state.
So far, battles were chosen during periods of expected Ok weather.

There were "misses" in bad weather where cruisers did not meet- and seakeeping would have modified potential speed.

I'm leaning towards Poor Seakeeping being OK,
if it means most of the time you can manage a "useful" speed level for your fleet.

So far in wars, people have been fighting in good weather.
There were some unseaworthy (<0.75) DDs caught in a hurricane and some sunk.

There were MTB and Landing operations delayed for lower sea state.
So far, battles were chosen during periods of expected Ok weather.

There were "misses" in bad weather where cruisers did not meet- and seakeeping would have modified potential speed.

The lesson I got from the Caicos war, and Snip's problems with hurricanes, was that poor seakeeping gives you a bad time in storms.  In the Caribbean, you have hurricanes, or nothing.  So my ships that are more or less confined to the Caribbean theater, like my GTBs, those can accept crap seakeeping.  I believe in that war you noted that seakeeping corresponded with sea state.  A .6 seakeeping DD (snip's E class) started risking swamping in Sea State 6 and was pretty screwed by Sea State 7 or 8.  In a small and calm sea like the Caribbean, something with weak seakeeping works.  In the North Sea, you can get away with it operationally by always sending them home when the weather starts to get bad.  In the Atlantic, or the Pacific.....you can't exactly find a sheltered harbor if things go sideways.  1.0 Seakeeping is the 'guarantor' that weather effects aren't going to be shipkilling. 

Personally, I've always wondered why some of you guys struggle for 1.20 Seakeeping all the time, I've only done it on specific classes that are purpose-built to go out into the most awful weather and expected to perform at peak efficiency.  1.0 to 1.05 is my typical goal even on capital ships, since nobody is trying to fight in weather conditions so bad that waves are breaking over a 7m bow, I mean dang.  But as DDs have gotten to 1500t and now seakeeping is something that can be taken into account, I've been aiming for 1.0 even on DDs.

Plus, like stability, I'd say that seakeeping has a small variance on survivability in combat.  If your DD for instance, has 1.0 seakeeping and it's in a battle in sea state 4.  It takes some non-deadly hits, but it would have taken on some water.  Now its effective seakeeping is more like .8.  It's still good and not in danger.  A .6 seakeeping DD that takes the same hits and goes to .4 effective seakeeping....is foundering.

I see it as more of a crew comfort perk, especially for ships that will be out at sea for weeks at a time. If you run into any weather your ship and crew will be in better shape after if the seakeeping is higher.
