Looks great, the only issue maybe the large sail stern will result in rotation towards windward, as the smaller sail aft will be insufficient to counter the rotation.
Have you watched the video of her sailing? The combined Centre of Effort of the two sails is designed to balance the Centre of lateral resistance of the hull and Centre board. See what you think. czcams.com/video/pFdcmUlV-Xc/video.htmlfeature=shared
What a bloody magnificent job. Not sure about that flat sail though, it will spill a lot of wind. But the auto furler is cool. Have you tried it without a centreboard. I have seem a similar craft on FB and reports were that the amas and hull provided enough lateral resistance and a centreboard was not necessary.
Not sure why you would use shock cord as the tension cables for your out riggers. That should be dynema which is stronger than steel cable and doesn't stretch. All fore and aft forces are just being handled by the the carbon fiber tube
That's a very good point. The original purpose of the shock cord was only to hold the akas into their sockets, but still allow them to swivel. Dyneema would do that and brace them too. Thanks for the suggestion.
Your roller reefing doover works so much better than mine did.
Nice work Graham. She looks very comprehensive and well thought out.

Thanks. Have a look at the sailing video. The sail works better than you'd think. The roller reefing is taken from Matt Layden's Paradox design.
