smarttune is designed to replace your existing turn screw. (forestay/backstay/shrouds/diagonals).
Live Data to your Phone or Instruments
Four-Time Winner of the Volvo Ocean Race
“Matching forestay tension to the wind and sails is key to upwind performance “
Former Sailmaker and America’s Cup Coach
“Forestay sag is measured by forestay load, and controlled by rig and backstays. Accurate knowledge of forestay sag enables you to repeatedly adjust this to give the optimum sail shape for best performance throughout the race”
Ocean Race Competitor and Olympic Campaigner
“Installing smarttune is as simple as taking turns off a turn screw to adjust the mast rake – this is definitely a system anyone can install on their boat.”

Set your rig up to known settings and see the real-time effects of adjustments to match conditions.
Built to Survive the Toughest Ocean Environment
smarttune is durable and waterproof (beyond IP67), tested to destruction and built to withstand all the elements and rigours of the deck.
smarttune is factory calibrated for immediate use out of the box and accurate to within 2% of maximum working load.
Data logged through the smartfittings manager app, integrated with GPS & ready for export to sailing analytics software.
For Boats of all Sizes
Available in 5 sizes, from 5/16” to 3/4” (turnscrew size) meaning there’s a smarttune for every boat.
The Latest Wireless Technology
No need for cables or wires, the device communicates with your phone via Bluetooth up to 15metres while sailing, and with on-board instruments via our gateway over longer ranges.
Low weight, low widnage
Designed by engineers from Cambridge University in collaboration with sailors. Precision design, optimised for low weight and low windage.
smarttune is powered by easy to source batteries: 1 x CR2032 for 5/16″ turnbuckle size or 2 x AAA for all others.
With approximately 6 months of battery life.
what size smarttune sensor is right for my boat?
The easiest way to figure this out is to measure the male threaded stud that is screwed into your current turnscrew. The different sizes correspond to the thread sizes:
|Imperial Thread||Metric Thread|
smarttune feeds data to your phone via the smartfittings app straight out the box.
