That would not be fun.  No sir.

Given what you're supporting with this ship, would it be better to cut the speed by a knot or two in favor of more aircraft?  At least get enough to put up a few scouts/bombers and a respectable CAP?

A tiny carrier that is basically about lending a bit of air capability to a surface group.  Eight planes means hard decisions about what's embarked - eight bombers for ASW work, or eight fighters for air cover.  Or I suppose four of each in a convoy escort role.

Speed is of course excessive for convoy work, or even patrol functions with Union sloops, but appropriate for keeping up with frontline surface forces chasing raiders or stuff.

And the mentioned Icebreaker-cruiser.  More of a proper cruiser than Penguin, which was more of a light patrol ship overbuilt so it could bully sea ice.  The 'Ice' is capable as a cruiser in its own right and a bit faster, but maintains the same heavily overbuilt design, including a thick and deep torpedo defense and thick end belts to better improve her abilities as an icebreaker.  Coupled with modern diesel-electric propulsion, she can stay out in the rather violent southern sea for months at a time.

Range at Cruise is 12,075nm

Playing around with ideas for a late 1930s run of cruiser.  As it stands, lighter vessels will be filling up my mid-30s designs for the most part, with a planned one-off patrol cruiser to supplement/replace the Penguin in the Terra Del Fuego station, but that station requires a very special set of requirements for an icebreaker-cruiser.

Looking at possible new guns as well, principally a deck and hoist for the 90mm DP gun when I refresh it, and a more powerful 180mm gun, possibly a /55 caliber variant with a heavy shell to get its performance closer to the 8in gun class without the additional weight. 

The following is a VERY early conceptual design:

Quote...As I've mentioned before, protective decks can be problematic...

Oups... this is a bullet.
SS corrected to "armored deck".

The basic problem is

Quote from: The Rock Doctor on October 21, 2024, 06:43:23 PMOne option for a 1935 torpedo-boat.  Compared to the preceding A/C class, they're 100+ tonnes heavier, but have an extra 0.6 knots of speed, extra 500nm of cruising bunkerage, and an additional 50mm AA mounting aft.

Seakeeping is nominally below 1.00, but would be fine at 33.5 knots I'm sure.  It's a function of the newer engine year requiring more speed to maintain the 50% machinery weight.  Adding a transom into the mix completely messed this up, so I skipped that altogether.

Snip noted long ago that 'poor' was likely the case for most real-world DDs.

Every so often something comes up where I feel the need to clarify how I *attempt* to marry SeeKrieg
with our Springsharps.

How exactly to treat various seakeepings is something I had to struggle with early on.

Snip's DDs with ~.72 seakeeping, rendering them less than poor and unstable ...in a hurricane comes to mind...some sunk.

Reality is, a large vessel handles waves better than small vessels, regardless of nominal seakeeping.
Destroyers rarely can make full speed except in fairly flat water.

I had the realization that accounting for seakeeping was needed, but
could be cumbersome, and I needed a method to evaluate it.
So what I decided was
A) only do it when it looks like it might matter - saves paperwork.
B) in rougher seas, look at the average freeboard height.
    - considered the bow height, but that heavily effects seakeeping in the first place, and was easy to manipulate with weird heights (odd a DD with a 10 high bow...)
C) If the waves are taller, that's an issue and the vessel has to slow down.

I was not expecting to look at the exact seakeeping numbers, but rather adjust that freeboard
height by 0.75 / 1.0 / 1.20 / 1.40% based on the 'poor/standard/good/excellent' text - as that was quicker to check and do than hunt through the SS for the exact number for each class

So a Destroyer with a 3m average freeboard and 'good seakeeping' of 1.26 would be able to go max speed in waves up to (3x1.2) 3.6m.

Granted, if anyone else is running the battle they may take a different path.

However the path I chose would not take into consideration the exact # for seakeeping, and so would penalize you based on the 'poor'.

A specific note stating the speed at which seakeeping is 1.0 is likely but not guaranteed to be noticed,
