Passage Planning

Here are some tools that may help with passage planning:

  • RYA SafeTrx  – This is a replacement for the CG66 scheme and has a supporting mobile app for skippers of all types of leisure vessels and small craft. This scheme gives HM Coastguard the information they need to mount a search and rescue operation if you get into difficulty.
  • This external link explains the wider system and how to register your yacht.
  • The app is free to download and there is no charge to use it although yohttp://RYA SafeTru will need to pay for mobile data.   Here is an external link to a RYA howto video for the RYA SafeTRX app.
