yep,
as with nearly every other sail on the market.

not enough outhaul makes the sail back hand heavy which translates down through the legs into the fin. crabbing persists etc.
not enough downhaul makes a sail feel heavy.
this is one of the reasons people use adjustable outhauls. bag it out off the wind, tighten it up upwind.
to fat a sail entry is very poor for upwind sailing. a windsurfer is a planing vessel not a yatch.
