In the last post we talked about the need to know when you are really going fast; not just thinking you are going fast. If we know when we are fast should we not be able to work out exactly what we are doing to make the boat go fast ? As we described in the last blog post we can record boat...

We all know the feeling, we hit the top of a wave the boat surfs, accelerates then goes quiet, everyone watches the numbers on the mast instruments and at that point you set the highest speed score for the day. You put a score on the board for everyone else who helms the boat that day to...

We’ve haven’t written anything here for a while so this is us getting back into the habit… VMG (Wind) - Distance travelled towards the wind divided by time. VMG appears on a lot of marine instrument systems but is in our opinion not well understood. The standard definition is; VMG = Velocity...

In any sport its important to do post match analysis. Sailing is no exception. With all the races that we do on Jengu we try to assess what we did right, what went wrong and what we could do better next time. The sources of information on any sailing boat are vast. There are literally dozens of...

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...

Reviewing the data collected for Jengu racing to St Vaast using Rockit over the bank holiday weekend. There was a lot of debate before departure as to which weather model was going to be right GFS or ECMWF. A lot of time was spent reviewing the maps from Predict Wind and Wind Guru; pretty...

We are very pleased … All the hard work is starting to payoff. 3rd in class and 8 seconds behind second place… Bill/May 2018 Originally published May 21...

Six coats of anti foul on the keel looks good…. now all we have to do is avoid getting stuck in the mud ….thats all. Bill/Feb 2018 Originally published February 14...

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...

The beginning of November saw us return to the Solent again for an informal weekends sailing with London Corinthian Sailing Clubs offshore group. The Not Race and Hot Toddy evening have become a traditional end of season outing. Its a simple format, we get together at Hamble Point on a Friday...
