Rotor-Rig Marine Design
Racebox is a race signals and finish timing program for sailing clubs. It uses a relay or a micro-controller via a USB cable to control the hooter sound system and uses either the traditional 10-5-Go sequence or the common 5-4-1-Go sequence. It can also control a light to give a visual aid to starting. It is easy to use, free and open source.
On the Fittings page is a directory and images of the Rotor-Rig custom hardware for dinghies. The STL files for most of the fittings can be downloaded free of charge via the links on the page, so you can 3D print your own!
