Good observations Marc ,
nothing stupid about those comments .
As you suggest in taking the current fastest 20 ,--We have basically taken the I-20 specifications as the class model and given a little room to upgrade slightly from there . An added 30 sq ft of spin area is allowed for 410 lb and above existing heavier cat designs to equalize their performance potential .
Many catsailors are preoccupied with one or more National championship races or multiple vents during fall , still currently waiting patiently for the web master to get the site up who also races in numerous classes of cats and monohulls , will persevere and keep you updated .
Thanks
Carl
