Don't know about a sub-80' vessel... but I had over 4 years on a guided missile cruiser with a large bulb covering the sonar dome, and can tell you in heavy seas, as the bow is coming down hard, the bulb would add a side-side lateral shimmy motion at the bottom of the downstroke (for lack of a better term).

As our berthing (sleeping) quarters were in the bow at the waterline level, I can tell you that it is one thing to be pitching vertically displacing your body 40-50' in a matter of seconds... but that shimmy at the bottom was enough to toss you out of your rack if you weren't smart enough to wedge yourself in...

Of course that boat was 533' long...
