This paper presents a numerical model for the smart detection of synchronous and parametric roll resonance of a ship. The model implements manoeuvring equations superimposed onto ship dynamics in waves. It also features suited autopilot and rudder actuator models. aiming at a fair depiction of the control delay. https://www.spidertattooz.com/China-Glaze-I-Believe-In-Snuffy-0-5-oz-84679-p12258/
