[Jefgte]

IMO, the speed is low for a commerce raider.
I note also the short range - without sails

Jef  ;)

[Tanthalas]

Im gona go with Jef here the range is a bit short, sails would proly help with that for what its worth.

2,375 tons cargo capacity - 1,000 troops and paraphernalia in fighting condition, 375 tons extra supplies or wiggle room[/tt]

Besides general questions of technical feasibility and the like, I'm curious whether this would count as 1 BP (4,000 tons*0.25 for Merchant Standard) or 0.4 BP (4,000 - 2,375 = 1,625*0.25 = 406.25).

Yes, I'm aware that BP are no longer a rule-relevant concept; put it down to habit or shorthand, as you please.

I would say, because it is a transport the misc weight does not count so:
3951 - 2375 = 1576 --> 1576 / 4 = 394 --> 0.394$
with the capability to transport less than 600 men.

The second is a very small nice little ship, but I would call it a patrol boat.

[Valles]

'Commerce Cruiser' seemed the best thing to call a ship designed to regulate trade and traffic through Japanese proprietary waters and into the Seas of Okhotsk, Japan, and the East China Sea. They are in no way, shape, or form intended as raiders. Perhaps 'Regulation Cruiser' would be better?

As for transport capacity, last I checked, the information available in the 'knowledge base' subforum gave two tons per person as the baseline 'transport ready to fight the day they finish unloading' figure. Certainly that was what N3's rules had it as. Has new data come available, or did I miss a mention in our new rules?

[Nobody]

Good question, I thought it was 4 tons per solider for longer travel, and 2 for very short ones. I could be wrong though.

[Walter]

Maybe today with a bit more luxury, it would be 4 tons per soldier, but back then the 2 ton figure given by the SS notes should be the figure to use, with half that number for short distances (or something like that).

[Korpen]

SS is always a bit iffy when dealing with space restrictions rather then weight restrictions.
As an example I post two liner, the only difference is that one of the ships is that one has 6m higher hull, giving her about 14 000m3 more space in the hull (or about 4900 GRT), but almost 2000 ton less misc weight. By our rules the low freeboard one would be the better transport, despite having on space for passengers to exist in...

Luxury isn't the issue.
'Beans and Bullets' are the issue.

We're not thinking about the soldier having a warm bed or a bit of walking around room. We're thinking about Springsharp having allotted enough space- and enough food and water- for this soldier to be aboard ship for a few weeks. We're also talking about weapons and ammunition for the soldier, fodder for horses, tents and poles, etc. There is a lot that goes into moving a troop around. As I have said in other threads- myself, 4 changes of clothes, two pair of boots, some rain gear, half a dozen paperbacks, a few days worth of non-military issue food, and sundry personal necessities... basically me, my weapons and ammo, a duffel and a large ruck (volume wise) weighed in at right at 500 pounds- I know this because they were putting us on a scale.
Now, this wasn't even enough gear to take me into combat; this was just enough crap to move me into theater! This was me and about 4 days worth of stuff to survive on, and about 5 minutes worth of carefully conserved ammo. Imagine what it would have taken for me to have fought a single battle!

Drifting Frozen-White Thistledown, Nippon Commerce Cruiser laid down 1875

Displacement:
   850 t light; 890 t standard; 1,008 t normal; 1,103 t full load

Unlike some, I do not have a problem with the range as I assume that she is not really intended to hunt on the high seas. If she is intended to haunt the costal trade of neighbouring states I think she can do a fine job.
If anything I think you should consider making her shorter to make her more manoeuvrable (yes I am aware that it will hurt speed).
   

[Valles]

And finally, the big boys. Decided to up the ante, tonnage-wise - she's now more-or-less the size of the 1875 HMS Dreadnought, though quite different in a number of other respects. I'm internally debating whether or not to try adding on-deck secondary weapons... given the low hull, casements are impossible, of course.

Behold! First-pass effort of the Useful Burdens class! Ugly, top-heavy looking sucker, isn't it? I find myself worrying simultaneously that it might be too modern or too old-fashioned... And of course there's the question of detailing, which I'd certainly be interested any opinions or suggestions on.

You know, I kind of doubt she will fit 1000 men; if all space were used inside the hull and then some superstructure is added, she would have an enclosed deck area of only 2 600m2 (assuming 2m low decks). That is without taking things like funnel uptakes and machinery spaces into account. So I think you really need to add about two decks more to get a hull large enough. If she would be a sailing ship (no space needed for engines and fuel) she would have a GRT of about 1600 gross register tonnage.

And finally, the big boys. Decided to up the ante, tonnage-wise - she's now more-or-less the size of the 1875 HMS Dreadnought, though quite different in a number of other respects. I'm internally debating whether or not to try adding on-deck secondary weapons... given the low hull, casements are impossible, of course.

   For and Aft decks: 3.58" / 91 mm
   Forecastle: 1.20" / 31 mm  Quarter deck: 1.19" / 30 mm

I can see some potential issues here.
I take it the main belt is intended to go from wetherdeck to ,5m below the waterline in order to protect the machinery for the turrets?
Splitting the belt in an upper and main portion would make that a bit clearer.
The gun layout with three centreline guns seems a major weakness as it gives you really bad ends-on fire. This can be a major problem in the sort of melees one can expect between capital ships, the fact that she is long and slow makes that worse.
Also, single full turrets are quite inefficient, the armour of a single mount is about the same as that of a twin turret.

But I really like that you went for guns with real power!
