When you have volume enough, it's the width that counts for early planing.
US147 <-> FU141:
93 <-> 80 or 65 <-> 50 at the tail.
The length of th FU141 is 246 compared to 240 of the US147 which facilitates a more passive way of getting on the plane, but I think the US will definitely plane earlier, go better through lulls and point better.
