There are many different types of Junk Rig out there but all have the same basics in common.
An unstayed mast and full length battens.
Classic Hasler, Arne, Split Rig, Aero Rig, etc
Maybe, when we get back to some sort of post Covid normality ( lucky Aussies and Kiwis), members who might be inclined, could do a short video of their own particular rig.
Maybe one segment filming on a quiet day to allow raising of the sail to explain the particular quirks of their rig and another segment, if help can be found, with the boat sailing, demonstrating the various controls in action, including reefing, the various parrels in use and anything else which might be considered useful to a newbie.
Showing the partners and mast steps, deck strengthening,
Sheeting arrangements and the rational for same, etc.
With regards to building a sail, I find both Arne's and Slieve's instructions quite good.
Personally, when I built my Split sail, I did a lot of reading and asking questions on the website before I attempted to build. You can't get around the fact that you will have to do some reading. And then I did the actual work on some small practice panels and things written in the notes became a lot clearer.
But still you worry when working on your own with no-one looking over your shoulder big you're making a mess of it.
But it worked out ok, and Mk2 will always be better than Mk1.
So maybe members video their own boats and then either editt the lot ntoo one video or load them onto a YouTube channel?
