There are two ways to fix this: the first is to make the main belt longer (to do that, you can either adjust the length of the belt directly, or you move the forecastle and stern breakpoints further from the center of the ship, making the forecastle and the stern shorter). The second is to reduce the speed, that will reduce the amount of space needed for the engines and hence the amount of belt length needed to protect them.
Ether make the engine plant and/or mags smaller, or make the for-castle and/or quarterdeck a smaller % of the hull. Manually fiddling with the belt length can give odd results sometimes.

Your ships don't seem to be that much better than my counterpart designs despite having much more tonnage and being several years newer. Does tumblehome really make hulls that much lighter?

its the buldges, you get artificial strength and stability from them (not to mention the aditional internal volume with a narrower deck than would be required otherwise). If you realy want to see somthing freaky dig around till you find one of the round BBs from N3.

On Akikaze, the speed needs to get up to or over 24 knots, otherwise it's not eligible for the small fast rules allowing the lower strength you're using. Easiest way to do that will be to cut the range back to 2000 nm and use the freed up strength for engines.
Fixed it. Its now a 24knotter, 27knots trial speed
