Sail From Home
Free online resources to help pass the time.
Check out the RYA campaign #SailFromHome on their website: https://www.rya.org.uk/programmes/Pages/sailfromhome.aspx
Suitable for both juniors and adults, the campaign is full of different activities including eLearning Youtube clips and activity sheets (e.g. about weather and tide) and eSailing with Virtual Regatta.
It's not the real deal in terms of being on the water but is a way to pass the time during this uncertain time.
