Tony Mack

Owner of McFly, Winner of the JCup 2020

“With our J111 one design class (or any similar OD) the margins are very close, ANYTHING that can help us go a little faster can be invaluable… we can quickly see that smartlink is an essential product that will provide us with the next competitive edge.”

Crew of Sphinx

Classic German 12M Yacht, built 1939

“smartlink has caused great amazement! We knew the backstays are the gas pedal of 12 m yachts, but never had the value… We were able to repeat our trim again and again… the load sensors have given us so much information about Sphinx we can use to get faster.”

Andrew Mclean

Team Leader, Systems Engineering INEOS Team UK

“At INEOS TEAM UK, we consider Cyclops Marine our ‘go-to’ experts when it comes to wireless load sensors. Forging a close relationship with our suppliers is one of our core values, especially when that company manufactures in the UK.”


Safety and Performance

Live and logged load data on any running line mean you can learn and repeat your fastest settings and preserve the integrity of rigging, avoiding any nasty surprises.

The Smallest & Lightest

smartlink compresses advanced technologies into the most compact package possible. Crafted out of Titanium (2t-20t) or Aluminium (Nano), optimised for low weight and low windage.

Strength & Durability

Built to survive for months in the toughest ocean environments, and even more waterproof & durable than the first iteration of smartlink. smartlink² devices have astonishing working loads, and won’t break till far beyond their maximum working loads – they are tested to destruction. 


Data logged through the smartfittings manager app, ready for export to sailing analytics software.



Paired with our gateway, smartlink² is compatible with most modern marine electronics systems. Find out more about connecting smartlink to your displays.


smartlink² is factory calibrated for immediate use out of the box, and accurate to within 1% of maximum working load.

For Vessels from Superyachts to Kiteboards

The Latest Wireless Technology

No need for cables or wires, the device communicates with your phone up to distances of 20m while sailing, and with on-board instruments via our gateway over longer ranges.
