LINK is the most advanced and comprehensive platform available for managing all your vessel need. This easy to use, all-in-one, custom engineered solution offers everything from monitoring and control, to document storage and mobile data management. LINK ensures nobody is in the dark. The LINKCloud enables manufacturers, dealers, owners and crew to check up on a vessel from anywhere in the world at any time, mitigating problems before they arise. It provides complete monitoring and control of all connected onboard devices with custom status notifications and alerts for any connected component, such as battery faults, engine issues, vessel movement and water leaks. Alerts can trigger user defined actions and are sent via SMS, WhatsApp or Email. The LINKCloud stores historic logs which can be recalled as needed, enables the sharing of documentation, and offers direct messaging between all parties involved in the vessel. LINK is a fully bespoke, completely customisable, ever-expanding eco-system that has been designed and manufactured in the UK alongside leading yacht builders. It not only gives owners peace of mind but also makes life easier for crews and vastly reduces warranty costs for dealers and manufacturers.
