[PCW] Advice on rolling tendencies to powercat newbie

[Robert Deering]

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.

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.
Ira Braun
