Hi Mr. Roberts
The SC 17 was the first catamaran I ever sailed. What a revelation it was. I have been a fan since.
The website mentions the rudders have a series 63 section. Are they designed to operate in the bucket upwind or does that happen only when reaching?
If not, maybe rudders with more area could be used (with mast rake) to give the boat a better drag angle racing upwind. It would be neat carry one set of foils to make it the ultimate beach boat and one set for racing around the buoys. That would be little extra investment to have essentially 2 boats.
What is the design displacement? The SC 17 I sailed on seemed better able to handle an extra passenger than many other cats it's size.
What is the design waterplane beam of the hull? Are the hulls any different from the original SC 17?
It is nice to see a new cat with a lower aspect ratio sail plan. Not all of us sail our boats around the buoys. Reaching fast is the best part of catamaran sailing.
If I was in the market for a new cat there would be no question which one to choose. I hope you sell as many as you can build.
