From the original SPIRIT to the mark three.
I completed the boat last week and put it into the water yesterday morning, and was delighted with its performance (Mk2b).
I live on the coast of NSW in Australia. Some time ago I bought No.2751 (the one featured on your site). I am currently racing the boat here in Australia in several IOM fleets. The elliptical rudder works perfectly and the boat is at full potential now, points higher than the TS2 and the Topiko. Neither are faster off the wind.... Thanks for a great boat, I have never felt another IOM that glides to windward like the Three. All your efforts are appreciated here.
