In the ShipName.zon file. Open the ShipName.dat file, and then click on the "zon" button upper-right of the screen, then in the dat file again, select the main ship node (like 7:Node - NDD_Fubuki as an example), then click "Model Preview" link to get the ship to show in the window. After that, click on the blue circle & green square icon for "Toggle zones editor" that is just above the picture of the 3D artwork, and your ship should then have another window to the right, and at least one sphere, usually right by the conn. But click on the "Boxes" link in that right-hand pane. On some of the DD, Ducumus made the boxes smaller, and none by the bow, especially none low, so while you might get an explosion, it won't "damage" anything. You shoot it at a 90 though, about the middle, and it'll blow sky-high. Compare the Fubuki to the Asashio in the mod, and you'll see the differences. You want them to be more like the Asashio. You can add boxes, or just re-size the ones that are there, and move them around some maybe. You do have to be careful with that though, else you'll give them a glass jaw. You could also compare them to, or copy from the Stock versions.
