The lines were taken from the Vincent, a Falmouth Pilot cutter built in 1852 for the Vincent family of St Mawes.

Video Spiral-Test -Manoeuvre for detailed identification of Yaw Stability using Samples of Cruise Ship
published on 29 September 2021
This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.
