Weights definition tool can be used to set first category of weights. When you launch the tool for first time (with ship instance selected), the Ship workbench initializes ship weights with Lightweight ship (equal to ship displacement) that is placed on the ship geometry center of gravity X coordinate, and at design draft height. Usually there are at least 2 relevant weights:
 * Structure.
 * Main engine (or several of them).
