I was playing around with this when I noticed something odd, when I thought of giving the hull some shrapnel protection the required main belt to cover engine and magazines are longer than the ship and yet no construction warning appeared, a known bug?

No one?

...the belt length isn't listed on that design, so I can't say.

As a side note, that would make a fairly respectable destroyer leader, there.

These two statements are related, I think. Make the hull wider, which lets you get more of the equipment and stuff under the waterline. Should help.

But shouldnt SS give a construction warning?

What do you mean by "construction warning"? Something like, "If you build it, it will go up like a Fillopine candle"?

And Brock's right, the reason the belt doesn't cover the machine/magazine spaces is that they are so large on such a narrow hull that they are above the armored deck. Kinda like the boilers on the original Lexington class BCs.

No, like the other its giving, Armor Belt longer than ship, Weight to much for hull, how about hull to small for engine...

But none of those things are happening. If you try and make the belt any longer, then it will give you a "belt is longer than the ship" warning. You CAN build ships that don't have full armor protection, it's just a bad idea. SS isn't set up to stop you from making poor decisions, just ones outside the laws of physics. Remember, it will let you put way more firepower than there is deck room for, as long as the hull displacement can support the weight it doesn't care. Unfortunately SS doesn't seem to thing 3 dimensionally very well when it comes to spacial issues. That's why we use RL ships for inspiration and the input from others for that "can I actually build that" aspect.

Scale drawings also help too.

Its just a result of how SS works. It splits above waterline and below waterline into two separate pieces rather than taking the entire hull. It assumes that all the magazines and machinery spaces are below the waterline so it has to expand lengthways when more machienry is added. In practice, the machinery would extend upwards as there are other space limitations; the need for rudder rooms, magazines, shafting runs etc. all of which need the machinery pretty much in the middle portion of the ship.

It's a bug I have encountered as well, you are correct in that there is no warning.

Generally I interpret it as "my engines don't fit in my ship" and a sign that I need to reduce speed.

One fun and easy way to do this is to take a high speed cruiser design and add a 1mm+ torpedo bulkhead. Since it adds interior voids, it squishes the machinery spaces out of at least the citadel and sometimes the hull. Often the lack of interior room means there is no benefit and sometimes a loss of torpedo resistance.

The % Hull below water is as RA explains, critical stuff sticking up. When one is armoring such a ship, one needs to remember to have a taller belt as a result, beyond protected flotation concerns.
