Opinion A Corrected Version on Positioning of Pivot Point
by Capt. Santosha K. Nayak - published on 18 November 2020
Understanding the fundamentals of the pivot point is highly required for understanding the alteration of the courses. Pivot point is an imaginary point on the vessel which turns on a circular path on the perimeter of vessel’s turning circle when the vessel makes a turn. The knowledge about the position of the pivot point in a manoeuvring situation provides the ship handler with the information on the geometry of motion of the ship.

Video How to Launch a Pilot Boat–Behind the Scenes at Point Hope Shipyard
published on 20 June 2025
Welcome to Point Hope Shipyard in Victoria, British Columbia, Canada. In this video, I follow the float off of the Pacific Navigator, a hardworking pilot boat that serves the Port of Victoria and Ogden Point. We watch as the vessel is pulled along the marine railway, rotated on the turntable, and positioned onto the cradle. Once secured, the cradle lowers to float-off depth, and the Pacific Navigator fires up her engines for a short harbour spin before returning to duty. Some segments,...

Video SAMMON Demo Planning FtLauderdale Arrival with comments
published on 20 January 2021
This updated video shows how easy it is to develop an arrival plan with the SAMMON Planning Tool. As a sample the arrival from appraoch until the berth to Ft. Lauderdale is used under strong current of 2kn. At the simulator training courses where we used this tool for preparation of a manoeuvring plan during the briefing sessions all nautical officers involved stated afterwards: "Why don't we have this tool on our ships?"
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...

Video Volvo Penta – Mighty Jobs – Piloting the Arctic seas of Norway
published on 11 March 2020
In this episode of Mighty Jobs we meet the piloting crew of Buksér og Berging in Tromsø, Norway. Their Volvo Penta-powered piloting boat covers around 42,000 nautical miles every year. That’s the equivalent of traveling around the world twice. The Volvo Penta IPS system makes it possible to pilot ships under all weather conditions.
