    Short answer is yes but not thru the wind range and angles that americas cup or Flying Nikta can do ie mostly beam reaching and below . Long answer since I do not have access to Gomboc i have done some linear calculations of lift ,righting moment at various speeds with certain assumptions...

    Thinking about reshaping foils when I found the photos of the canard moth I pulled a few really old pics. I remembered creating airfoil dagger boards and rudders for a variety of boats back in the 1970s .Later in 1981when I bought my first keelboat nee original sport boat Salty Dog an...

    Work slowly progresses fairing up the leeboard verticals . I cut out the actuator pivot and was quite happy with the carbon consolidation around the tube . Should easily be strong enough I hope !, I also put the boat up on wheels partly for sanding and painting outside but also because we were...

    Meanwhile I collected the stainless steel “T” s to allow interchangeable mainfoils and 2 x5/8 ss rods as pivots from John at Arcright . wrt fairing one of the advantages of straight foils is that you can make up fairly accurate 4.5 inch wide sanding blocks cutting the airfoil profile out of...

    My green approach to going to work is a modified cat trike road with fairing and electric assist  12 km one way in 17 mins give or take a minute. 8 watt hrs per km approx quite a bit less juice than a Tesla needs .

This consisted of1200 gm uni and 400 gm biaxial over the mid part with an extra 1200 uni at the forward edge for 50 mm...

    stunningly effective ; endplates usually  more than double effective aspect ratio which would be approximately 4 therefore typical 75% of wind tunnel CoL which is attributed to a nominal infinite span but really is adequately endplated like your foil was. What foil  of Bora's did you compare it to?
