Hi Mike
Saw the race from the back of the pack and the front also at times ,-there was always a good mix at the starts of 6/0s -HT 18S and I-20s mixing it up ,-it varied as the H T s do not like waves diving and pitching too much ,but the 6/0 are better in them not having those wide inter 20 flat bow sections that slap into them ,-
Reaching the 6/0 was better with its large jib , and straight downwind with its larger spin .
Believe the 6/0 sailed by Steve and Kenny last season in some distance races took line honors that included a good field of I 20s and several other boat types .
Sailed the 6/0 in the 98 and 99 Worrell --its an excellent powerfull well built with better boards and rudders ,-fast cat .
The 18 HTs are ideal buoys racing cat designs for flat water .
