As wireless load sensing becomes a core tool in both racing and cruising circles, Cyclops Marine’s smartlink ² range stands out for its simplicity, flexibility, and broad application. With Safe Working Loads from 250 kg to 20 t, this compact, wireless sensor is equally at home on a foiling dinghy or a 60-metre superyacht.
Now in its second generation, the smartlink ² lineup has evolved into a high-precision, fatigue-tracking load sensor that requires no hard installation and no electronics retrofit. From a quick-deploy vang sensor to a long-term backstay monitor, smartlink² delivers high-value insights with minimal effort.
What is smartlink ²?
smartlink ² is a lightweight, wireless load sensor designed to fit in-line with any soft connection - halyards, sheets, lashings, or strops. Each sensor has a central load body with radiused end holes, designed to accept soft shackles or Dyneema loops. There are no wires, terminals, or fittings to install—it’s a truly plug-and-play solution.
With a waterproof, anodised aluminium body and internal Bluetooth transmitter, the smartlink² connects wirelessly to the Cyclops app or a compatible marine display via the Cyclops Gateway.
Typical use cases include:
- Backstay, checkstay, and deflector strops
- Headsail tack lines (especially Code sails or furlers)
- Mainsheet and gennaker sheet loads
- Halyard tension monitoring (e.g., jib or gennaker)
- Top-down furling torque loads
- Cunningham, outhaul, or vang loads
- Dinghy shrouds, trapeze wires, or vang systems
- Temporary use during rig testing or sail development

smartlink ² = One Sensor, Many Jobs
The appeal of smartlink ² lies in its mobility and versatility. Unlike dedicated rigging sensors like smarttune ², which remain fixed in the rig, smartlink ² can be moved from system to system as needed. It’s a perfect fit for race teams refining tuning protocols, sailmakers looking to quantify sail performance, or owners wanting to validate their rig tuning post-refit.
On one day, you might install it on a gennaker tack strop for an offshore leg. The next, it’s in the backstay circuit helping optimise headstay sag. smartlink² allows sailors to experiment, log, and learn—with minimal friction.
What’s New in the smartlink ² V2 Series?
The new smartlink ² range incorporates significant hardware and software upgrades:
- Extended battery life – Smart power management means you can deploy for longer without recharging.
- Higher data resolution – Improved accuracy and sample rates for more granular analysis.
- Better Bluetooth stability – Stronger signal, even in carbon-rich or complex installations.
- Fatigue cycle tracking – Cyclops’ proprietary system now logs load cycles over time, giving a real-world estimate of fatigue life for any connected component.
This last feature represents a major step forward: it turns smartlink ² into a real-world rigging lifespan monitor, logging how often—and how severely—your sails, furlers, or rigging are being stressed. This data has real potential for integration into rigging audits, insurance evaluations, and long-term refit planning.
Connectivity: App or Integrated Systems
One of the key advantages of smartlink² is its flexible connectivity:
- For dinghies, sportsboats, and smaller keelboats, smartlink² connects directly to your smartphone using the Cyclops app (iOS and Android), allowing you to view, log, and share load data on the go.
- For larger yachts, smartlink² integrates into your onboard electronics via the Cyclops Gateway, feeding live load data to instruments and multifunction displays (e.g., B&G, Raymarine), enabling real-time decision-making at the helm.
This dual-mode capability makes smartlink² suitable across a full spectrum of platforms—from Olympic-class dinghies to transoceanic racing yachts.

Full Range: From Dinghy to Superyacht
The smartlink ² lineup covers six models, ranging from dinghy-scale light loads to superyacht-grade tension systems:
Model | SWL | Typical Applications |
smartlink² Atto | 250 kg | Dinghies, kiteboards, trapeze systems |
smartlink² Nano | 1 t | Sportsboats, small keelboats, light halyards |
smartlink² 2.5 | 2.5 t | 30–40ft monohulls, furling tack lines |
smartlink² 5.0 | 5 t | Cruisers and racers in the 40–50ft range |
smartlink² 10.0 | 10 t | High-load mainsheets, offshore multihulls |
smartlink² 20.0 | 20 t | Superyachts, custom rigging systems |
Each unit is IP67 waterproof and built from marine-grade materials for long-term reliability in demanding environments.
Smartlink ² - The Simplicity Advantage
It’s worth reinforcing just how low-hassle the smartlink ² really is. No mechanical modification. No special tools. No need to modify terminations or integrate with rigging hardware. If you can install a soft shackle, you can install a smartlink².
And for teams or owners who already have a load-sensing mindset, it offers a fast, accurate way to validate rig changes, measure performance loads, or simply avoid overload scenarios.
Conclusion on smartlink ²
The smartlink ² is an elegant piece of rigging intelligence: simple to deploy, flexible to use, and smart enough to provide long-term rig health data. With support for everything from dinghy vang tension to superyacht code sail furling loads—and connectivity options for both phone-based sailors and full electronics suites—there is a smartlink ² to suit virtually every sailor.
Whether you're optimising sail shape, setting repeatable trim targets, or gaining confidence offshore, smartlink ² delivers rigging insights with minimal installation and maximum return.
