A big year (and for one so young)
Many of the most successful yachts this summer have A+T instruments
A+T was only founded in 2015 and has now developed a complete range of extremely well engineered instruments, processors, autopilots and sensors. A high proportion of A+T’s business is for upgrades to superyachts and systems for new- builds. In the raceboat market A+T is also establishing itself as the weapon of choice for high-level instruments with some 30 per cent of yachts in the recent Maxi Rolex Cup in Porto Cervo using A+T. In this article we look at case studies of a few of these. Critical to A+T’s development is feedback from the racing community and navigators where it specialises in turning around suggestions fast. Leopard 3, the canting keel Farr
100ft maxi, has had a great season, taking the race record and 1st
IRC in the Aegean 600 and then again line honours in the more recent Middle Sea Race with Will

Best navigating and race captain Chris Sherlock. These wins were straight out of the box after a major refit including a new deck from Baltic, mast from Southern Spars, elliptical rigging from Carbo-Link, PLC from Olectric and new A+T instruments. The previous A+T system was upgraded to a full Ethernet bus, a full rack of the colour big format displays (BFD) on the mast and the latest processor from A+T, the ATP2X. This provides full two way connectivity with the PLC using Modbus for a wide range of sensors and sailing information. More importantly this new range has a user-programmable layer using the Node-RED open source software to allow the custom generation and manipulation of new variables without compromising the underlying strength of the A+T standard platform that is so important for a boat which does long

Velsheda upgraded her wind instruments with the new super rapid response A+T wind sensor and at the same time fitted BFD displays to her existing WTP/CANbus system. Under navigator Grant Simmer, Velsheda won her first regatta at the Palma Superyacht Cup again straight out of the box. Captain Barney Henshaw-Depledge was very pleased, stating that ‘these displays were very well received by all – especially the owner, great purchase and thank you to A+T’. The BFD can respond to context
