I am the happiest EX-World Cat boat owner on the planet. I had an HTS with twin diesels and never had a boat with more problems. Andrew Brown at W.C is the chiefest of liars and I hope you don't have any problems with your boat. I also hope you don't have one of these with diesels. My boat design was so bad my insurance totalled it because the cost to fix the problems caused by W.C's design exceeds the value of the boat.
Good luck. They do ride pretty good though when they run.
