Good point with the rolling. We yet have to throw any furniture around. If
I were crossing oceans I might look at a different design. However a lot of
the roll has to do with the hull lines of the boat and the speed etc. The
weight aloft may actual dampen a roll. For example the worse sailboat I ever
owned was a 32 footer, that had over 50% of its weight in lead ballast way
down in a narrow fin keel. That boat had a terrible snappy roll and I got sea
sick. A sail boat without its mast often has a very snappy roll. The boat I
took Calif. to Europe, was a rather firm bilge, relativity shallow draft,
less ballast ratio (about 30%) and I never got sick, despite some storms
with up to 40 foot seas.
My current Symbol has a V bottom, with a fair keel and hard chines and does
not seem to roll, as much as perhaps as one of those wonderful round bilged
passagemakers . Also with a power boat, you can change your angle of
incidence with the waves--sort of like a sailboat tacking--to find the course
of least roll (might take your a little further). Also speed can be varied
to change the period of roll. In fact I have been surprised that we do not
roll more, since I thought we would with the sundeck, a flying bridge hard
top and dinghy on the top of the sundeck.
