About hydrodynamic forces and moments acting on ship hull in maneuverability, there are many theoretical and experimental studies in full load condition, but few studies in light load condition. One of the authors represented approximate formulae predicting the hydrodynamic derivatives on ship maneuverability in trimmed condition. When we use these formulae, we need the derivatives in light load even keel condition. In this paper, we investigated about the hydrodynamic derivatives on ship maneuverability in even keel condition including light draft. The following formulae were obtained. Y'_β≒π/2k+1.4C_bB/L Y'_r≒π/4k N'_<Φ^β>≒k N'_<Φ_r>≒0.54k where Y'_β etc.: nondimentional hydrodynamic derivatives k: aspect ratio (nearly equal 2×draft/ship length) C_b: block coef. of full load condition B/L: breadth/ship length
