How the smarttune 1/4" Fits into Your Sailing Setup

The smarttune 1/4" is perfect for smaller raceboats, dinghies, and sportsboats, making it ideal for:

✔ Shrouds and sidestays – Maintain repeatable rig tension for performance gains.

✔ Backstays and forestays – Optimise sail trim and mast bend with real-time load data.

✔ Race tuning – Track and refine settings for consistent high-speed sailing.

Safety and Reliability

• Overload Protection: Do not exceed 150% of the calibrated load, as this may cause permanent sensor damage requiring recalibration.
• Calibration: After extended use under load, allow 1-2 minutes for the sensor to return to zero when unloaded.

Unlock Performance with Real-Time Load Data

The Cyclops Marine smarttune 1/4" transforms rig tuning by providing instant, wireless load intelligence, making it an essential tool for competitive sailors. Whether optimising rig settings for racing or ensuring safe rig tension, this precision-engineered sensor delivers the data needed to sail faster and smarter.
