I would appreciate your views as to their safety value to our slow circle boats {average speed is under 60 mph}. I am aware that APBA requires them as well as drag boats under a certain E.T. but are they really worth the moola and requiring them?? We are in the difficult process of adding and deleting rules to our Nostalgic racing classes and I value everyones opinion here in the forum. I run one in the faster hull {averages 65 mph for three laps}, but at what speed should they be required? I will take your input to the rules meeting. Thanks in advance!
