You have to remember, there have not been many if any boats consistently running the speeds the Mystics run. JBS runs in the 170's to upper 180's all the time. There not many skaters, MTI's or anything else that can run those speeds especially for any length of time.
When we did our speed run the one thing JT brought up is what is the speed that an MTI can handle before worrying about a delam problem.
I know quite a few Skaters that had major delam problems. Several of them from being in storage.
I would not knock Mystic. They are the first to be building boats to run over 200. I would think any of the other makes would have the same problems if they ran the same speeds.
