Hazel and I have just set up an account for the JRA on Instagram. The account name is 'Junk Rig Association'.
As yet, there's not much there, but we hope to post photos or short videos regularly. Clearly, we need suitable content so, if you have photos or short videos of, eg, your junk rigged boat under sail, and you're happy to have your photos/videos used in this manner, please get them to us - you could post them here, for example, to give us access to them, with your permission to use them on Instagram.
Even if you don't have suitable material, please follow the account (if you're active on Instagram). At least it'll get a few junk rigged vessels on your feed!
Many thanks to Kevin for his support with the idea!
