Hey again Jim,
Again, great seeing you on the EC 2016 beach this morning!
I snipped the immediate below from an earlier post of your's (CaptnChaos) to this thread as I thought it more conducive to this thread's subject, the 2016 EC and did not want to "pollute" the original thread's subject of Hobie's new Spinnaker too much.
Snip/ (from CaptnChaos' post in the "We have two great new accessories for Hobie Islands!" thread)
There was (Snip/ Snip/) an AI with his own clever design of a furling spinnaker AND furling jib AND completely modified hull ... amazing engineering in his setup. His tribe name was island mutant. He had a back stay and side stays ... quite complex.
Spinnaker looks beautiful.

I missed this guy's launching... did you see it, Jim?
Also, I did not get any photos of his jib or spin deployed, did you?
That unique, very heavily moded, AI was very interesting... he said the "aerodynamic" shell that he created (from carbon fiber) only weighed 6 or 7 pounds and it covered from the top of the bow, where it structurally attached a bowsprit for the jib and spin, down the bow and across the entire length of the bottom to the stern where he attempted to create a planning surface and also about halfway up the sides, bow to stern! Pretty amazing. He claimed better surfing and was hoping for better planing but was not yet sure on this.

Photo at Stern (showing more of the following mentioned steering mechanism but also a bit of the white planning surface viewable below it):

He also had an alternative steering mechanism that was really nice, completely foregoing Hobie's stock setup. He claimed at least a 5 or 6 times advantage compared the stock steering in "gear ratio". There were 4 separate steering positions,in the cockpit either side or out on either tramp... very well done!
Photo above showed the large "partial pulley" like attachment to the rudder that the main steering lines were attached to. These lines went through a couple blocks on either side of a very small "traveler" mechanism mounted on the Aka brace behind the seat. Separate lines pulled the traveler car from side to side from either the tramp or from the cockpit (via yet more blocks!).
Some more photos of the steering mechanism ( consisting of many blocks and lines):

Looks quite complicated but it did work very very nice!

P.S. Apparently Drop Box images do not display well on the Hobie site but the links should work...
