This gives you 65.0 for the uni, slightly FASTER than the 2-up sloop (25 seconds /hour).
This is exactly what the other systems are showing and what appears to be true ont he water. Mind you those 25 second/hour is a pretty small difference (0.7 %) and less then 1 % = 36 second/hour. I call that pretty comparable around the course.
For the record : The F16 class officially strives for a reduction in rating numbers and even for ratings close to the F18 class. It is the official standpoint of the F16 class that US PN numbers for F16's are too slow ! We believe this to be unfair to the other sailors on different designs.
