This was posted on another website. Not sure how true it is.
"If you're a fan of the George Linder designed Shadows, Superboats, Challengers, etc., the 25 Powerplay is the same hull, but with more length, more freeboard and slightly more beam, giving a MUCH smoother (and drier) ride, while still having all the performance and handling characteristics that made Linder's hulls so much fun to drive."
Can anyone confirm?
