Unfortunately you won't find any book on that design, the design doesn't exist anywhere, (especially in sailing books of any kind), it's a totally new concept. It's not really a sail in the sense of the word sail, (primary power source for the boat), because it isn't the primary power source, it was only ever expected to provide 30% of my power requirements, and worked more as an energy amplifier, (kind of like an air conditioner or heat pump works, by taking existing power and amplifying, or making it better).
The wing does nothing unless you are already traveling at least 6-7mph, then it starts working, (it's driven by apparent wind, and doesn't work without it). In other words if you sailing upwind about 10 degrees off the wind and the wind speed is 8 mph, and your forward speed is 8 mph, the wind on your face and across and driving the main sail is 16mph. Because the wing organizes and amplifies the air going over the mainsail, the wing forces the mainsail to do work in conditions it clearly shouldn't be able to do anything but luff, (stall), and shouldn't work according to all sail theory (like being able to sail almost directly upwind).
Keep in mind I only designed all this stuff to suit my own purposes only, and only wrote about it because I was asked to by friends on the forum.
We bought our first TI back in 2010 and wanted to use the boat mostly in the keys for far offshore scuba diving, from the factory, the boat does not have the correct classifications for what we needed, or the speed that we needed so we redesigned the boat to suit our own purposes, (90% of everything was designed back in 2010). We owned 3 TI's over the years and used the daylights out of them most every weekend doing what we love to do. As we wore out one boat we would buy a new one and just transfer all the gadgets to the next one. My criteria was to have a boat that cruises 8-10mph in the typical light wind conditions in the keys, (around 5-10mph winds most of the year), with a strong ability to sail upwind, (around 10-15 degrees off the wind), because when south of the island, if the wind is coming from the north, without that ability you can't get back to shore, (we learned that one the hard way). We wanted around 100 miles per day range, (because the keys are fricken huge), and we would often dive as far as 30 miles from where we launch, (you can count with one finger the good launch sites in key west, (fortunately that spot is only a couple blocks from our house). Yea we made incremental changes over the years to improve things as I thought of them, the wing jib came along in around 2012-2013, which improved our performance from being able to point 25 deg off the wind and sail 6-7 mph in 5-6mph winds with a regular jib. To my final design which easily achieved 8-10 mph cruise speed upwind in around 5-7 mph winds pointing around 10-15 degrees off the wind, (dozens of incredibly boring youtube videos out there showing that). Obviously I thought it was kind of cool stuff, but got roasted by the Hobie community pretty much constantly,,, apparently 98% of the AI/TI community just loves the boat as it comes from the factory, and frown on any mods, (I'm fine with that), I only did the changes to suit my own purposes, and boy did we enjoy our TI, (more than anyone can imagine, checked all the boxes for us), so much so we had around 1/4 million road miles over the years putting the boat in any body of water we could find all over the country with Hobies on the roof and camper in tow, (and some we shouldn't have). Unfortunately I had to sell the boat last year under doctors orders because of a back injury. But I still have all my stuff stored in the garage, just in case my back gets better, and I can pick up a new TI, (fingers crossed). Personally I would just pick up a Hobie kayak sail for your Adventure, and rig it to the boat, and have fun with it. You learn a lot messing about, which was always the most fun part for me. We really loved our adventure series boats, and strongly feel Hobie invented a whole new catagory of sailing craft, (still feel that way). We had 6 kids and now have over 6 grandkids, (big family), this is one of the many videos that sold me on the TI [youtube2]https://youtu.be/Pb4orK9MLXE[/youtube2]
