Video Wind pure drift encounter - practical experiments for getting useful data
published on 8 July 2022
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!
Video You Won’t Believe How A Pilot Boat Is Hauled Out for Refit
published on 24 September 2025
The Pacific Guardian pilot boat is first seen in Victoria Harbour near Ogden Point before making her way to Point Hope Maritime Shipyard for a full refit. This video captures the entire move process, from the cradle lowering into the harbour, to the careful docking of the vessel, to her move across the turntable and onto the spur line. Some of the footage has been sped up, since the cradle lowering and lifting are slow, deliberate operations where every movement is checked and rechecked....

Video Who are Marine Pilots? Australasian Marine Pilots Institute
published on 13 March 2025
The Australasian Marine Pilots Institute is the professional body representing marine pilots throughout Australasia. It assists in the setting of standards, safety management and provides support and guidance with ongoing professional development. AMPI provides advice to regulators on how to improve operational safety in our ports, and ensures that member pilots and their organisations continue to lead in world’s best practice. Together with its partners, AMPI has developed a set of...
Opinion What is a Tug's Bollard Pull and How İt is Calculated?
by Capt.Alpertunga Anıker - published on 24 November 2022
The Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.
