I think this might be a little crowded with guns, tell me if I'm right...because otherwise, I kind of like the firepower/speed combination of this ship.

Yes, a bit crowded, cut the number by a bit. Say, 4 guns only amidships.
For cruisers use "mount with hoist".
1" deck armor should be enough.
175t misc weight is excessive, 125-130t should be enough.

Draft is a bit deep for my liking, BC is a bit low. I'd decrease beam too. by 1-2'.

Modified a bit.  Fewer guns, less draught.

Made a rouge sketch of her.
I suspect that the intention is to have the B and K gun to be superfiring, but as springsharp does not place guns at forecastle height, the raided mounts have to be forward or one of them will not be able to fire forward.

im gona have to agree with Korpen, I learnd the same thing on some of my first ships
"He either fears his fate too much,
Or his desserts are small,
Who dares not put it to the touch,
To win or lose it all!"

I'm not sure I understand...how would I rectify this to get the biggest broadside?

P3D

As of Korpen's sketch not much space is left for torpedo tubes .

The quarter inches of the deck and belt armor is unnecessary. I think most game system considers like 1" resolution in belt and 0.5-1" resolution in deck armor.

I realized that machinery takes up a lot of the space, you could increase the draught back to 19' (German cruisers of WWI had about 18-20" draught).

It looks like it fits, actually.

Sachmle

Ya, barely, the forward side turrets can't elevate all that well because of the superstructure and the B and X mount can't fire over the A and Y mount, they're to close together.  Now looking at it I'd like to slide all the upper works backwards toward the stern so there's more open deck on the bow for the wash to break at speed.

Also, kinda looks like an AA cruiser w/ all those 19mm
