The difference between Gross Tonnage and Net Tonnage

At Humber Maritime College we have state-of-the-art marine simulators to teach our Merchant Navy cadets in an environment close to reality, preparing them for a career at sea.

This book was only available in some areas, now the author has created an e-book version. Furthermore it´s available on amazon as a paperback.

Completely new book on Ship manoeuvring techniques based on new revealing facts which have been brought to light. Must read for all the mariners to understand the behaviour of ships and how to control her behaviour during manoeuvring.

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!

A in-depth video explaining how DUKC® works.

Trinidad and Tobago Pilots' Association Anniversary

The TRENZ SIRIUS is now available at a reduced price for a limited time. Until December 31st, 2024, the device can be purchased for €1,300.

Google Maps and ECDIS (Electronic Chart Display and Information System) can be considered to essentially serve the same purpose. While Google Maps is used for finding our way on land, the ECDIS facilitates navigation at sea.

Editors note: A film of a pilot boat has just been published on YouTube with the title "How Dangerous being in a Pilot Boat..." on YouTube. I'm not sure if this really shows a dangerous maneuver, maybe the experts can comment on it here.
But in principle it is problematic to approach the ship in such a small Pilot Boat in the wake from astern and cross the waves there. I remember an accident from Finland in December 2017 where the boat capsized and people died. Is this situation shown here...
