Hi all and in particular Paul McKay. After my start in the sailing world some 65 years ago with a kayak and advancing through dingies, some Olympic classes then monohulls and windsurfers. I feel the urch after having moved to Indonesia and not having sett foot on any sailing vessel the last 10 or so years, to build my dream boat. Some of my priorities are comfort, safety, ease of use but still speed if I want so.
This landed me on a 12 m (40 ft) trimaran and after my first choice of softwing found the Aerojunk a better and easier option.
I'm a bit rusty now but I remembered from my windsurfing time that we outhauled the sail according the wind condition at the moment we rigged up.
I see that the Aerojunk in fact is fixed rigged regarding the chamber, which is not optimal.
So my suggestion and question is:
What if... we fixed a thin running rope, say 4 mm, from the bottom sail leech grommet to the back of the wishbone, over a wheel to the next wishbone back/end, there over a wheel to a wheel (block) in the local leech grommet so back to the back over a wheel to the next whishbone. All the way up to the top where it is connected to the single line sheet running down to the cockpit.
The idea is, when the wind pressure increases the sheet will tense, which in it's turn will tense this outhaul arrangement and flattens the sail, thus reducing the chamber.
In this way I think we will have a dynamic adjustment of the chamber regarding the windstrength.
Looking forward to any input.
