Ian Cherrill's Rotor-Rig organisation was started a few years ago with software called "Boat Timer" that aimed to make getting accurate race results a bit easier. That morphed into a project called "Racebox" that does both automatic sound signals and race results. Racebox is free software - take a look at https://www.rotor-rig.com/racebox for more details.

During the Covid Lockdown, Ian started collecting map information about sailing clubs and their race courses. It was a lot of work analysing satellite information and different information sources to get the right location of marks and clubs. But like many of us during Covid, there wasn't much else to do. It eventually became a project called Jettymap. Later it seemed a better idea to move them to the UMap project on OpenStreetMap and so the sailing maps can be found there now.

More recently Ian created some 3D designs for boat fittings and made them available on the Rotor-Rig website. This proved to be very useful as some of the prototype components of the Frensi, such as the branded endcaps on the spars and gooseneck 'beads',  were produced on a 3D printer.

But the Frensi is the most important project. It has been clear for some time that we need to get all those unused Lasers in sailing club boat parks back on the water and make sailing a cheaper sport, less wasteful and with an easy way to get started. Hopefully the Frensi will do that.

Ian can often be found sailing  a Solo at Frensham Pond Sailing Club in the UK.
