I use Matt Layden's roller reefing standing lug sail on the Paradox sharpie he designed. I described it in the newsletter a while back.
There used to be a website at http://smartsailing.se/English/index.htm/ that described a more high tech version of a roller reefing main. It had an unstayed, rotating mast, full length battens, a box around the boom that was fixed at a right angle to the mast (it is even possible that it did not move at all relative to the mast), metal hooks at the ends of the battens, and a sliding car with a bar those hooks could hook into. To reef, you just released the halyard. The spring-loaded boom would roll up the sail. When the next batten reached the level of the boom, the hook at the end would push the cross bar on the sliding car back a little bit, then a bungee would pull it forward again to pull it over the hook. I forget the arrangement at the luff at the sail, but there was some automatic hook there as well. Tighten the halyard, and you're set.
I wrote to the inventor when I discovered the website, inviting him to write an article for the JRA Newsletter. I never got a reply. But doesn't Google archive everything? Is it possible to retrieve the old site?
There is also the Omer soft wing sail: http://www.omerwingsail.com/
Peter Estrup and Joan Bergstrom patented an unbattened lug equivalent of Slieve's split junk, or if you prefer, a lug sail version of a balestron rig: http://www.balancedrig.com/. Perhaps one of the people who market the rig now could be invited to publish with the JRA. There is a brochure, but it's marketing blurb.
The proa designer Rob Denney is working on a telescoping unstayed wing mast. He hasn't updated www.harryproa.com since June 2008, preferring to post news on the Yahoo harryproa discussion group. He also bulds unstayed carbon masts for balestron rigs, and says he can build such a rig for less money than a stayed alloy rig. Cheap carbon masts might be interesting for junkies, to better feed the habit.
