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!
Here’s a nice video of the recent sea trials with ‘South Esk’, a new Interceptor 48 pilot boat for the Montrose Port Authority in Scotland. It was fairly rough during our sea trial days with a fair bit of wind, and although it was touch and go flying the drone, we managed to capture some wonderful video of her and Ederra 7 at the entrance to Cork Harbour in a gale.
