just like the hundreds of other OD events for many classes if there is no weigh in and still racing under the class OD rules.
just like your weight of the boat and or any modifications (bottom jobs, removing weight, etc....) - they don't check it every time, but you are still racing under the
class OD rules.
for some reason, people think the total crew weight (40 + or -) 2-4 days before you actually race (not actually when the class rule is effect) makes a big difference and
crew weigh ins have been part of the scene. as you can see a lot of the more popular classes have done away with them without
losing boats on the line.
smart for the owners and class to do this, should attract more to the fun (owners and crew).
