Radius of Gyration

A vessels radius of gyration (K) is a measure of it's mass distribution about the axis of rotation under consideration. It can be calculated by taking the root-mean-square of the mass distribution;

SQRT( (Σ[mass x distance]2)/Δ) ) units are length, i.e., meters

Moving weights further outboard increases a vessels radius of gyration.
