Full length video of the theory proposed in 2008 (originally in three parts).
Deals with the Apparent Pivot Point, the Center of Lateral Resistance, the Ship Generated Current and much more.

About the theory :

‘’The concept of pivoting point was described by the the British admiralty As the point of no drift angle. Further developments were introduced by Hugues Cauvier in 2008 (‘’The Pivot Point’’, The Pilot, October 2008) and triggered much discussion on the Pivot Point: what is it? Where is it located?’’
- Pivot Point, Port Revel - Ship handling Training on Manned Models, 2014

‘’(The) article(*) is one of the most important works in the theory of the pivot point.’’
- Control of the Pivot Point Position of a Conventional Single Screw Vessel, Kobetsb , Popovychb , Zinchenkoa , Nosova , Tovstokoryia , Kyrychenko, Kherson State Maritime Academy. 2023

‘’So-called added water mass or ‘ship-induced current’ (so described by Canadian pilot Capt Hugues Cauvier), is water movement induced by the rotation of a deep-laden ship in a swinging basin. These very real effects are demonstrated spontaneously, visibly and clearly when using manned models’’
- Capt. Cliff Beazley, FNI, Managing Director, Port Ash Australia, in Seaways Magazine, Sept 2017

‘’3 years after Captain Cauvier’s article, Dr Seo writes an article that is published in the Nautical Institute magazine Seaways. The article adds weight to Captain Cauvier’s argument that the ‘traditional’ pivot point is only the ‘apparent’ centre of rotation’’… ‘’ Professor Jeong from the Korea Maritime University wrote a short two page summary of Captain Cauvier’s article and was convinced that the ‘traditional’ pivot point was “not real” and not the centre of leverage’’… ’’ Dr. Carreno wrote a scientific paper on the shallow water effects on the ship’s pivot point and discusses a lot of the theory in Captain Cauvier’s article.’’… « He (Dr Seo) sends another nod to Captain Cauvier when he writes about the above scenario … “The account is mistaken in two aspects. One is that the pivot point is treated as a physical entity (as the fulcrum) … the other that the pivot point is treated as the cause. »

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,...

Opinion Pilot Ladder - The Weakest Link in Marine Pilotage

by Capt. Santosha K. Nayak - published on 10 August 2020

Pilot transfer arrangement is a sensitive topic to be discussed among the pilot’s fraternity. Although ships are designed and operated with compliance to the SOLAS requirements in all respects including the pilot transfer arrangements, there has been numerous deficiencies observed related to pilot transfer arrangements. The small deficiencies from the part of ships cause life threatening accidents for pilots and sometimes to the ship staff themselves. There are many instances of defective ladder and complacency in proper rigging of ladders has been reported almost every day in different parts of the world. Many pilots lost their life, severely injured for life and face many minor to major accidents. The latest incident being the Capt. Timothy Murray of Sandy hooks Pilot.

On duty 24/7, 365 days a year. The pilot service is always on hand when a ship is heading for or leaving the Port of Hamburg. Fleet Hamburg reliably brings the pilots on board the ships and that is a fast-paced task. New challenges await every day. Find out more in this episode of "PORT IS WHAT WE DO".
