Recommended SAR applications

The RYA SafeTrx app monitors your boat journeys and can alert emergency contacts should you fail to arrive on time. It is an app for smartphones that allows you to track your journey on your phone. The app provides all recreational boat users, particularly dinghy cruisers, PWC users, RIB users, canoers, kayakers, wind and kite surfers and smaller boat users with an easily accessible and simple to use means that can inform HM Coastguard of their voyage plans and dynamic location in the event of distress.
