Article GPS (Part 2), physical and technical errors of GNSS - an error analysis
by Capt. Gunter Schütze, Thailand/Germany - published on 26 February 2020
In my announced sequel, the second part of GPS, it is primarily about the technical and physical operational and functional limitations to which GPS is subject. These limitations, in part, have serious implications for the accuracy of GPS, and even go as far as limiting the functionality of GPS in its functions or even making it impossible. In doing so,

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 Presentation of manned ship models at Port Revel Shiphandling Training Centre
published on 24 October 2019
Port Revel is used for shiphandling training of maritime pilots, masters and officers on a 5 ha lake with 11 manned model ships representing 20 vessels, and 4 tugs at scale 1:25 and DGPS tracking system. Instructors are former maritime pilots.
Training on the scale models provides experience that could never be gained on real ships for the simple reason that neither ship-owners nor local authorities would allow such risks to be taken. Scale models allow the shiphandler to make mistakes....

Video Storm Bram sea trials aboard Northeast Pilot III
published on 27 February 2026
Here’s a video of recent Sea trials during ‘Storm Bram’ aboard the ‘all weather’ Interceptor 48 ‘Northeast Pilot III’ we built for the North East pilots at Newport, Rhode Island in the USA. With winds of Storm Force 11 and heavy breaking waves conditions were pretty wild, and proved a good test for her seakeeping abilities, especially her stability where she recovered nicely from a hard 90 degree knock down. Also respect to the seamanship of the captain aboard Fokko Ukena whom we filmed and...
