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...
Article New Study on GNSS Interference in the Baltic Sea
by GPSPATRON Sp. z o. o. - published on 12 March 2025
GNSS interference has become a growing challenge in the Baltic Sea, affecting maritime navigation, aviation, and critical infrastructure. While numerous datasets and services, such as gpsjam.org, spoofing.skai-data-services.com, and flightradar24, report high-altitude GNSS interference based on ADS-B data, there is a significant lack of studies focusing on ground-level interference.

Video Operation of POD Ships - Discussion on Efficiency comparing Conventional and IN-OUT POD strategy
published on 8 June 2022
In this movie the efficiency of two different pod operation strategies is compared: With azimuth propeller ships the Pods can be used in two ways to control the speed, e.g. for speed reduction: 1. by adjusting the engine orders, e.g. by reducing the RPMs to get lower speed - this means to drive the ship in the same conventional way as for twin screw vessels, 2. by turning both pods either in- or outward (TOE-IN or TOE-OUT) to reduce the forward thrust and therefore reducing the speed – the...

Video Safehaven Marine: Sines big day at Daunt and offshore F9 inc crash landing
published on 18 January 2022
If you fancy seeing what it’s like aboard during some rough weather sea trials, here’s a pretty cool little video of our Interceptor 48 pilot built for the Port of Sines. Some really great Arial drone footage and interesting POV (Point of view) with narration from aboard her in 5-6m seas and in 50kt winds 25 miles offshore.
How difficult is to land a drone back down on the boat in 5-6m swells and 45-50kt wind gusts? Pretty damn difficult as it turns out! Sometimes we fail as you’ll see at...
