Spinlock Sail-Sense
Spinlock Sail-Sense – Sail Monitoring and Management System

With a growing desire to use data to enhance the performance & enjoyment of our sport, Sail-Sense is a revolutionary sensor which helps you be smarter about your sail management.
Small and lightweight, Sail-Sense attaches permanently to the sail, measuring key performance data such as Hours of Use, UV Exposure, G-Force and Flogging (movement). It links via Bluetooth with a Free App installed on a mobile, tablet, or PC to deliver powerful analytical and performance data*.
Sewn to the sail either on construction or as an aftermarket purchase, Sail-Sense will wake up on movement and immediately starts logging data. Fibre analysis undertaken by Southampton University of sail materials, fibres and construction and the effects of UV and motion then allows the Spinlock Sail-Sense App to create a ‘health score’ for your sail. Sail-Sense also allows a sail to be tracked, traced and located and a full history viewed in real time. Each Sail-Sense identification code allows multiple sails to be managed through a single device and multiple users can manage a sail’s lifetime history.
The Sail-Sense App provides the interface between Sensor and Users, displaying the data in a simple clear format. Users are able to log, record, review and export all of the data recorded by the Sail-Sense sensor attached to a sail.

• Measures Hours in use, UV exposure, Flogging, Tack count & Location
• Creates a unique ‘passport’ for your sails, identifying make, model, construction date, dimensions and materials
• See how, when and where a sail has been used
• Accurately record sail condition and monitor degradation
• Tamper Proof record of a sails lifetime history

• Real time asset management - Live Mode: Full time visibility of product usage and wear
