He also mentioned
something about one of them having more "rocker" (I think that was
the
term he used), but I am not sure which one or even what it means
(something to do with the "upsweep" of the sides???).

rocker is the amount of curve from end to end. A boat with lots of
rocker is easy to turn but will not track as well as a boat with less
rocker. More rocker is probably going to cause the boat to be slower
as well.


Hmmm, I'm confused again... If "rocker" is the amount of curve from
end to end, then a boat with more rocker should have less wetted
surface, right? And I thought that less wetted surface meant a FASTER
boat????
