There is no such thing as a MAGIC loader. Each hull and set up has a different necessity. Loaders are a tuning tool that need to be designed for your application. Having said that,Nick's loader works very well in his boat and he built a very cool looking loader. That doesn't mean that it will work in every boat on this forum. The loader that MPD built for Lance's Liberty has a bunch of #'s scribed into the top of it describing the dimensions. When you buy into a program such as his, you have the option of trying about 20 different types of loaders. Also, what works in rough water will not be as fast in a smooth water pass. Two loaders would be ideal. If it's glassy , put the loader in that bites less water. When it's rough install the one that has the most bite. Don't forget about the shoe !!! This must be a very carefully orchestrated effort. All of this must work together to make progress. Remember that the deeper you run this hardware, the more aggressive the boat will handle. Jet boat drivers tend to chop the throttle alot and that's a big NO-NO when you start loadin' the pump real hard.
