There are ways to "cheat" in terms of adjusting a boat's comfort. Such as by hoisting something heavy, like a big anchor
, up the rig. It slows down the speed (& "violence") with which a boat rolls (roll moment of inertia). Though it does also lessen her ultimate stability. But the difference in her rolling motion will definitely be noticable.
The reverse is also true. Racer's with super light rigs, & heavy keels, really whip around quickly in waves. And it's utter misery being on a boat who's totally lost
hers. As denoted in many accounts of the '79 Fastnet.
