If you take the portsmouth mods for single handing a two person sloop, and the the mods for no jib on a sloop, the uni is faster. The only reason it is not always sailed faster is that you have a class with no min wt and feather wts are sailing two up. Seems like you have a generous rating no matter what. Yes, I have sailed with F16's, very nice, fast boats where weight is king, and no min crew wt is certainly an advantage in open racing. Just an opinion from an observer and fellow sailor, Rick
