I was approached recently by the guys at Cosworth about testing their new PI Garda GPS sailing system, and providing them with some data they can use. I’ve come across the PI kit before in my work with Skandia Team GBR, and Victory Challenge, but I’ve not seen it used on anything quite as small as a Moth. I’ve now had it on the boat a few times and should be able to publish the data here soon.
The Pi Garda system from Cosworth Electronics, is a sophisticated GPS linked to wind gear that records and analyses a lot of interesting factors such as wind speed and direction to produce key performance measures such as VMG and polars along with standard tracking data. On top of this the analysis software used can do a variety of analysis tasks such as; automatic tacking and gybing analysis and layline & startline tools, all synchronised with relevant video. I’m still learning about all the different features that can be done, analysed or added on in the way of sensors or custom fittings. Strain gauges, rudder sensors and inertial measurement tools have all been mentioned, but to start with I’m sailing with a system that has the ‘black box’ GPS, with an IMU giving me heel and pitch angles, all linked to some Raymarine wind gear mounted on the bow.
Testing has begun – so technical minds out there – what data would you be interested in? Data I’ve got so far to be posted soon.
