Racebox softwareÂ
Racebox softwareÂ
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.

Frensi - the friendly rig for your Laser/ILCA
Frensi - the friendly rig for your Laser/ILCA
The Frensi aims to make sailing cheaper and easier for people new to sailing and get more Lasers out of the boat park and on to the water. With a Frensi rig and a second-hand Laser, someone new to the sport can be on the water in a strong, easily repaired boat for not much money.
The Laser design is a classic and despite being first made in the 1970s the boat is still stylish and great to sail. The Frensi rig allows sailors to raise and lower the sail when they need to, making launching much easier. The bright colours and easy-to-handle "Lateen" rig make sailing a Frensi fun and relaxing.
The Frensi spars are made by Allen Brothers, with fittings from Allen and Clamcleat and a sail made by Morgan Sails.
The Frensi was launched at the RYA Dinghy Show 2025 and is now available to order in the UK. There's more about the Frensi at https://frensi.org.
