Designs for 1900 go below.
First up is a odd duck. Somebody at the Puget Sound Naval Shipyard got a hairbrained idea. "If we use 5"ers to keep torpedo boats away from bit ships, why not put them on a small boat to kill them?" The result is this modified Chauncy hull. It looses all torpedoes, its 3" gun and the two beam 6lbers to mount two 5"/50 on the aft deck. I think Im going to build it as a one-off so we have something to provide a in-game example of how big guns on little DDs work.

The working circle is going to be constrained to say the least. And at only about 10 feet above the water, the bow gun is going to be difficult to work. There is a reason that small DDs tended to have raised platforms for their guns. Does it work at all if you elevate the guns?
Not at all.
hmm... comparing and contrasting with this: http://en.wikipedia.org/wiki/Bainbridge_class_destroyer
I'll have to go dig out Friedman to get an idea of real freeboards on that guy. 12' might be high enough on the forecastle otherwise. The aft gun might need to be elevated for command.
With regards to how bad the Chauncy's are, there will be the successor class in the second half of 1900 that will improve on things. The Kitsap is just a modified run-of-the-mill Chauncy hull.
Well now that I can play with my BP, I leave this to discuss.

I'm thinking a few more tonnes of miscellaneous weight would be warranted for command facilities on the battleship.
Otherwise, I like her.

I will most likely remove (well, most likely thin so much it wont be worth keeping) the aft conning tower to gain some additional Misc weight to throw around. But cant do it now as unlike the G-man, I have not had luck getting Springsharp to work via Wine on my MBP :'(
My wine install is via home brew, if that helps, and I installed .net 2.0 (not sp1 or 2) with wine tricks.
That said, recalculating a ship under wine is slow enough to annoy me, so I've gone back do doing design work in a win 8 vm. The wine install will be useful when I break out Mac gimp and start doing bit maps.

Hmmm... I don't really consider 130 tons 'lots of misc weight'. 4000 tons of miscellaneous weights on my Oshima class BB over at Wesworld... Now
that is lots of misc weight for goodies. ;D
I would increase the freeboard a bit so that the 5" guns would become a bit more useful... but that is just me.

I would increase the freeboard a bit so that the 5" guns would become a bit more useful... but that is just me.
Any sort of fiddling with freeboard just breaks the ship. Should I draw it, I will most likely see if the 5" guns can be brought up to the main deck without issue. I put them low because I am sure they would not have there firing arcs limited by the 7" turrets there.
It is what I would do, not what you should do. I can understand that you have an idea as to how the ship should be. It is just different from what my idea is. IIRC my Shanxi design is close to the limit of "Limited use in heavy seas" which is about 5 meters so an increase of ~2 feet would force you to cut into the various aspects of the ship that you do not want to change.
OK, did some CAD work and found I should be able to move three casemates per side onto the main deck without hampering the 7" guns to bad.

One more that should not ruffle any feathers. These are just repeat Chanucys in every respect aside from shipping 18" torpedoes as opposed to 14.2". Because it was just a change in the misc weight definition and nothing else, I did not bother to make a new sim. They will be known as the Truxton Class rather then members of the Chanucy Class.

Something else to think about. The Spanish Destroyer Pluton was run aground at the Battle of Santiago. Presumably, she would have been available for the USN to examine. The following is an Americanised (and N-verseised) Pluton. I am hesitant to go for this design over the Chauncy/Truxton because of the range. They don't gain that much speed and I have room under the rules to improve the Chauncy/Truxton. Do you guys have an opinion on which is better?

I think the real question is what's the requirements for the N6 USA WRT DD range. That's going to drive your design decisions.
