Eric, I respect your opinion, even more so, your right to express it.
In the future, I will not participate in regattas where non spin boats are on the same course with spin boats. Those of us with spinnakers understand the situation, those without do not.
Cheers.
That's the most ridiculous generalization I've heard in a long time.
My primary racing is done in non-spin boats (Hobie 14, 16, 17). However, I've owned an F18 and I know what it's like to drive one downwind in a regatta - with non-spin boats on the same course.
