Port Ash Australia: Ship Handling Training & Research Centre

How to get information for wind & current limits to be potentially encountered by thrusters – or current? - this will be described in this movie:
- Measure Drift speed, due to beam wind with no propulsion;
- Measure drift speed using full thrusters
- Estimate wind & current limits to be potentially encountered by thrusters – or current...
- Finally there is a simple formula as Rule of Thumb: the transverse drift speed is about 7-8% of wind speed!
Another very good explanatory video by Knud Benedict. Absolutely worth seeing.
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 Association of Maryland Pilots took delivery of its fourth Chesapeake class launch from Gladding-Hearn Shipbuilding, Duclos Corporation.
Since the Chesapeake class pilot boat was introduced by the Somerset, Mass., shipyard in 2003, 22 have been delivered to 12 pilot associations throughout the United States.
