Advice on rolling tendencies to powercat newbie
Hi:
I recently purchased a 22 Glacier Bay Renegade, principally because I
was impressed by the lack of pounding in a chop (as well as the
increased interior room for the length. I am not new to boating,
having had a 48 foot motoryacht previously, among other boats. Having
said that, while I am very satisfied with the behavior of the boat in
a chop, head or quartering sea, my wife and I are quite uncomfortable
with the rolling motion in a confused, following, or beam sea. I know
these boats have quite a following on this site so I am asking for
advice as how to handle this situation. Thanks in advance to those who
respond to this novice in power cats.

My experience, though somewhat limited, is that all "cats" are uncomfortable in those situations. The only thing that might help is powering through which might be pretty wet and in some situations may make things worse. Sailing "cats" are sometimes a little better, because the sail loads up and keeps the boat from rocking as much, again, in some situations.

Ira,
The Glacier Bay 22 is notorious for rolling. The hulls are very narrow and
thus they tend to submerge easily in a beam sea or when a load shifts.
I have heard of a capsize event up here when a GB22 was used for pulling
crab pots, and as it was described to me, the lack of hull buoyancy was a
major factor - there could have been other factors that I'm not aware of.
Some of the motion you're feeling is natural for cats - they tend to
generally be more lively in beam seas when one hull is in the trough and the
other on the crest. Likewise a following, quartering sea can feel
disconcerting because the low volume of cat hulls in the bow means they tend
to submerge more deeply. You'll find a slight change of course can have
dramatic responses. Also, keep in mind that in a cat you're generally
sitting up higher which will amplify the rolling sensations.
Hope that helps.
