Video Wind Impact on Ships Turning Motion
published on 20 January 2021
This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...
Opinion Hybrid War at Sea
by Frank Diegel - published on 25 March 2025
Electronic warfare in the Baltic Sea is escalating rapidly, with GPS and AIS disruptions posing growing risks to maritime navigation. Russia’s hybrid strategy is targeting both safety and stability in one of Europe’s most critical shipping regions. Pilots and crews now face a new reality: navigating under threat.
Opinion How OpenBridge seeks to improve maritime workplaces
by Prof. Kjetil Nordby Institute of Design - The Oslo School of Architecture and Design - published on 6 May 2020
Lack of standard user interfaces across bridge equipment is a major concern for maritime safety. Pilots are in a unique position, as they are constantly exposed to new and differing bridge working environments, equipment, interface designs and combinations of systems. As pilots face this problem throughout every shift they need to put in considerable effort to adjust their work to the many user interfaces they meet.
Video Dynamic failure of pilot boats: Risk mitigation & management
published on 12 December 2020
Following a surf riding and broaching incident and subsequent collision by an experienced vessel operator, QinetiQ have been undertaking extensive investigations into the risk mitigation and safety management of pilotage operations. This presentation looks to discuss the risks presented during pilotage services, and provide a critical review of vessel design and service delivery approaches to understand the potential risk mitigations and management of pilot boat safety.
Video Yaw Stability of Ships - Basic Principles by Knud Benedict
published on 18 November 2021
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

Video San Ciprian’s new Interceptor 42 pilot boat ‘San Cibrao’ during rough weather sea trials.
published on 28 May 2020
Here’s a nice video of the rough weather sea trials of San Ciprian’s new Interceptor 42 Pilot boat ‘San Ciprano’. With the Covid-19 travel restrictions in place and the Guys from San Ciprian unable to fly here at present we’re having to do a remote ‘on-line handover’. So we made this video to give them every confidence that she is performing well, as she handled comfortably the stormy conditions prevailing on the South Coast of Ireland last Friday nicely, with winds of 50kts at the entrance...
