Their draft is the same, but average freeboard drops from 3.66 meters to 3.14 meters. That's why the seakeeping sux, going from 1.07 to 0.67.

You might be better off just to delete the torpedos and the 47mm and adding the 25mm in the original Springstyle than trying to tranfer her into SpringSharp.

Springstyle designs are perfectly legit in WesWorld.

It also has Big Gun, a simulation of naval guns.

for a 25% refit. You're making changes to light armament, and refurbishing her to extend her service life.

You're not reshaping her hull, or reboilering her to convert from coal firing to oil, or changing from VTE to turbines. those would be a 50% to 75% reconstruction.

And her original BC is 0.55, according to the original Springstyle.
