They crack because they made the hulls light and they suck, thats really just it.
Bryan Kemp has the original hull from his original stock/limited class ski. he fixed it once, and it broke again, however it did not break where he fixed it, it was at the front rubrail itself. It broke further down previously.
He does also have a brand new HS with a 160 kit. So far so good.
Im about 2 seconds away from buying a hydrospace....but they will have to get rid of their last of the original batch that they are itching to get rid of over here, so they can bring out the better stuff. They also have to figure out their sensor failure problems, steering and throttle cables, and gas tank filler issues. Then Ill buy one or two.
