Could you use inches for new ships, just to be consistent with "Seas of War"?

[maddox]

I don't have any problems thinking in Inches.

But I still prefer mm

[Earl822]

It is relatively simple to convert inches to Millimeters in most cases.

[Borys]

Ahoj!
It is a question of mindset. I can think in inches as concerns armour or gun calibre, but whether a 200 foot vessel is a lifeboat or a battleship I don't know - I have to recalculate into meters first.

P3D:  I don't follow you - the report presents both sets of measurements.

I see I've made a mistake:  it's 4000 HP, not 4000 KW, per shaft.  So that'll cost me around a quarter of the powerplant.  I wonder if the reduced machinery weight will let me reduce the hull size and thus keep speed from dropping too much...

[The Rock Doctor]

This is probably quite close to the battleship Gran Colombia will actually lay down in 1906 - since battleships are needed and this is as "cutting edge" as Gran Colombia can currently get. 

-the three deck-mounted 10 cm guns were meant to be an anti-airship station, but Springsharp strongly objected to my characterizing it that way.  If the EK is winked out of existence here, and there are no significant airship forces to concern myself with, I'll probably omit thise.

-Thoughts on the design in general?  I'm wondering if I need that much deck armor for the time.  Will have to poke around Jane's tonight.

[maddox]

the 200 foot ship is a TB. 66 meters, roughly.

200 feet is 2400 inch.

[P3D]

The design looks nice. The deck armor was usually distributed between seveal decks - the Tegethoffs had ~75-80mm of deck armor this way.

My comment was about having whole inch values (e.g. 304.8mm armor instead of 300mm), but only for the armor. The rest really does not matter.
But...sigh...I can live with 300mm instead of 305mm - a 2% difference in armor weight, that is.
