   Roger,

   The testing seems to be going well.  Your boat looks super and the small mishaps are only going to make for a better boat by the EC.  Keep us informed!  I'm loving following your progress, as I want to do a similar boat for solo tripping or daysailing with two.

   Cheers,

   Dan

     I liked looking at your blog, you stay more busy then I do.

   your speed with mirage drives alone is as good or better then my cat. yes I leave my peddles in almost all the time for tacking, my boat comes about easly but the extra speed is nice.

   question. please tell me about, anti vortex panels installed.

   Dan, Yes testing going ok I guess, I should be able to get it out late tomorrow again, will let you know how the fixes go. It has been fun and of course I need to build a new boat now and incorperate changes that I wish I had done differently. Can't wait to see yours going together.

   Teak, you can read about vortex panels here http://www.ikarus342000.com/Antivortexp.pdf 

   I have used vortex generators on experimental aircraft for over 20 years now and they work on wings along with tip end plates and they make an amazing difference. I am only just getting to test them on hulls. One thing is for sure is that water acts much different than air and is still puzzling to me but challenging as well and fun and cheaper. (but not cheap!)

   I could pedal my TI at 3 mph so I was hoping for more speed with just the drive but it will have to do. When not pedaling and the drive is in place I lock the drive so that the blades are straight down and act as a dager altho somewhat small. I am working on "stops" for the blades when they are horiz. and even with the bottom of the boat. If I can get the stops correct and at the right angle the  blades should act as hydro-foils and produce some lift but that is way down the list of things to do. Hopefully I will have more time than I did at NCC in order to take a closer look at your cat. Your hulls sure look like planning hulls to me. Have you got it there yet?

      I designed the boat my self, Looking at picks of many cats, bare hull with cross members weighs 220 pounds.

    I added more picks.

    Teak,

     

    That's good stuff.  I hope Hobie USA is paying atention to your boat as it would be a neat product.

    teak, 

    I gotta say, nice looking boat!  ...... and thanks for sharing those pics.  For "Most Innovative Boat Award" I think I gotta pick yours!  Sizzors being second (as this is not his first year), but who is third?

    Teak, any thoughts after viewing the anti vortex panels? Anyone else, have they been tried before by any of the sailors out there? Is it magic or wishfull thinking? I wonder what wizzard thinks? ... are they close to chine logs like he invented for his boats?....  those seem to work great for him.

      My thoughts on anti vortex panels.  ?????, seems like the reduced drag from less vortex could be offset by the more surface area drag, what about a covex shape bottom, good for lift and seems like the hard reverse chine good have same affect? just a thought.
