Learned a lot at Jasper, it was great seeing everyone and checking out all the boats.
It appears as if one of the major changes made to the XR-2001 hull in 2001? 2004? was the stern design. The older 01's had what I'll refer to as the "V-stern" while the newer ones have more of what looks like a "Box stern"; the latter having the net effect of increasing the distance of the motor mounting flange to the pad edge (fore to aft). Here's two pics illustrating the difference.

"Box Stern" :
Note the patented Allison "skid planer" on the newer hull. It looks like you could achieve about the same effect by putting one of these on the older-style hull.
