Yaw Stability is an important element of Ships Manoeuvrability - both for course keeping and turning ability. This first video in a series explains the Basic Principles of stability in steady state equilibrium conditions and the forces / moments involved. The role of the unstable moment due to drift angel and the stabilising damping moment due to rate of turn in the yawing motion will be discussed. Definitions of yaw stability during turning motion and on straight motion will be given. Samples of stable and unstable ship behaviour will be shown by Fast Time Simulation using the SAMMON Planning tool.
The next videos will demonstrate manoeuvres (e.g. Spiral Test, Pull-out Test and Zig-Zag Test) to identify and discuss the stability condition for ships and the different aspects contributing to yaw stability.

Nice explanation on turning and yaw stability. I think it’s important to consider all forces involved to the Pivot point and point of application of external disturbance, which changes according incidence of heading.

Video How Ship Anchor Works? - Procedure For Anchoring a Ship at Sea

published on 11 July 2020

#Anchor #shipanchor #windlass Anchoring is one of the very frequent operations onboard ships. A number of variables and external factors influence the duration and location of an anchoring operation. While the type of seabed is of utmost importance during anchoring, soft muddy grounds or clay bottoms are best preferred. It should be taken care that the anchoring bottom is free of power lines, submarine cables, pipelines or rocks. Various methods on anchoring include consideration of...
