You have to do a lot of work to an X4 hull to run over 70mph without "bucking". After taking too many drinks of lake water at 70mph+ I moved to a lot more stable plateform, the GPR!

aside from the 70mph buck would you be able to even get it to float

Welcome to the Greenhulk forums.

The "x4" hull was the designation used for the SD hull on the XP's up to 1996 and the SPX's till they stopped making them.
