Struct ShipModelDistance 

pub struct ShipModelDistance(/* private fields */);

Distance in ship-model coordinate units (1 unit = 15 meters). Hull geometry uses this space: .visual node matrices, the .skel_ext nodes hung off them, and the meshes they position.

The 15 is measured, and good to roughly +/-3%. That is the precision budget of anything derived from it: a position 100 m from the hull origin carries about 3 m of scale uncertainty.

The tightest evidence does not come from geometry at all. Solving the main-battery dispersion formula against published port dispersion gives 14.976 for North Carolina and 14.851 for Yamato (wowsunpack::game_params::ttx::constants::BW_TO_SHIP). That route is only independent of the geometry if the dispersion formula’s ship space and the .visual/.skel_ext space are the same space, which is inferred from the shared engine import name and not otherwise established.

Geometric measurements agree but individually are looser: Iowa’s waterline beam puts the scale at 15.06 m/unit, while the model bounding box against A_Hull.size[0] implies about 14.8 across the roster. The exported hierarchy carries no scale of its own; Scene Root, export and the hull nodes are identity. See docs/FIRE_CHANCE.md section 5.1.
