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,

Article A review of the ship’s pivot point: Science, Maths and Observation’ Where is the centre of a ship’s rotation?
by Tim Cummins, Harbour Pilot, Portsmouth International Port - published on 17 July 2020
This my attempt to do just that. This is a summary of all scientific papers and articles that I could find about the ship’s pivot point. I have added links to any videos associated with the publications and have also included any useful diagrams or equations that the authors published to help explain their research.
Video Understanding and Preventing Tug & Barge Risks
published on 15 January 2021
Blog: https://www.merrimacins.com/understanding-and-preventing-tug-barge-risks/ Understanding and Preventing Tug & Barge Risks The maritime industry relies on tugboats and barges for a wide range of applications. Tugs are used to pilot vessels into and out of ports, while barges are used to transport bulk materials. The relationship between tugs and barges is critical, as most barges are not self-propelled and must rely on the skilled operation of a tug or tugs for propulsion. At Merrimac...
Video S-100 in confined waters: an official IHO testbed and sea trial
published on 27 April 2026
What happens when next-generation maritime data is put to the test in some of the most complex navigational environments? This video shares insights from a major international S-100 simulator trial, delivered in collaboration with Carnival Corporation’s CSMART training facility and a wide network of global partners. Together, we explored how S-100 data sets perform in realistic, high-pressure bridge scenarios—particularly in confined waters where precision and timing are critical. Bringing...
