Weight belongs near the center of a boat, NOT near the ends.
Through the 50s, 60s, and 70s the argument about distributed vs concentrated ballast raged, and the net result - that concentrated is better - is correct, but for exactly the opposite reason you mention GreatKetch.
Distributed ballast results in lower rotational momentum, but greater rotational inertia. So, the boat is wetter, goes through the wave rather than over, then continues its pitch
(or roll, or yaw) after the force is removed.
The whippy, increased momentum of concentrated ballast is faster, drier, and more likely to give the crew the heaves.
