Found on YouTube. Created by "ISSIMS - Innovative Ship Simulation". Originally published on 2021-09-01.

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. Finally, a discussion of of ship’s hull form with loading conditions and elements like appendages completes the overview on effects of Yawing stability.
The next videos to follow will demonstrate other manoeuvres (e.g. Pull-out Test and Zig-Zag Test) which are also helpful to identify and discuss the stability condition for ships and the different aspects contributing to yaw stability.

published on 12 November 2020

Join Great Lakes maritime historian and antiquarian Brendon Baillod as he discusses the restoration and conservation of a rare and very early 1865 Thompson's Great Lakes Coast Pilot. Early coast pilot books were kept on every schooner and steamer and Lakes and contain important details about the history of harbors, navigation, obstructions and shipwrecks on the Lakes. This 1865 Thompson's is among the rarest and also badly in need of stabilization. Enjoy this two part series where this...
