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.
