Hello

Many tried to get the foundations of a F 20 class going but the main problem was the Inter 20 in the US which was the predominant 20 for years was very different from the H Fox which was designed to the F 20 EURO based CLASS RULE .

The inter 20 had 15 more sq ft of sail area in a larger sq top main sail - was 30 to 40 lbs lighter --and had other minor advantages .

I think the new 20 ft cat by NACRA may be a better basis of basic sail area --beam --weight and length from which to establish a F 20 class of the future .

Many design based rules and classes are based on what is refered to as a basic BOX RULE --the sides of the box being basic class dimentions measurements and specifications of length --20 ft --beam ? --sail area ?--min weight ?.

Other tops and bottoms of the box can be added from there with fold overs added ;]

HERE IS SOME BASIC INFO ON THE NEW 20 FT CAT

In Europe a ready to sail F20 C comes in at around €7,000(including tax) less than a ready to sail Marstrom Tornado!
