Mine handles the chop very well, especially if I trim the diverter for the conditions.
As far as being from Wisconsin, that's where mine came from as well. The manufacturer's plate shows that it was made by Ski Boats of Wisconsin, which is also out of business.
Don't try to make the boat too fast. 70 is about the safe limit due to the hull design.
Hello, I was wondering if you had ever gotten any useful info on the GMC CobraJet boat... I have a 1979 , 16 1/2 ft. that I just got and I am having one heck of a time locating info on this desighn too.
