Extracting Data from Your Boats Network
How do I get the information out of my boats network? Most modern sailing boats have networks that run on NMEA 2000 protocol or proprietary variants of that type. The networks connect the various devices on the boat together and allow the exchange of information. Rockit is expecting to receive...

Winter 2016 Updates and Upgrades – Bob-stays, In-haulers And Rudder Bearings
Jengu, as with any boat, is a work in progress. The more we fix and fettle the more we find we need to fix. As a consequence January 2016 saw us working on more of the issues with Jengu that had been highlighted after a full seasons sailing. Our number one priority was to check the rudder...
