First I am not very experienced, so take that in account
But, I think this whole rolling at anchor
thing is way over stated, Rarely have I ever had rolling at anchor
be a real issue, only once really and it was in a channel with a lot of current
that I believe had the wind
and waves at 90 deg to the current
. It was actually before the bridge in Clearwater, stupid place to anchor but we arrived very late at night and I didn't feel up to playing with unfamiliar shallow waters.
Anyway at least for me it's a pitching motion that is more likely as usually the boat at anchor is bow into the wind
and waves, so not being oriented fore and aft would have me rolling.
making I sleep where and when I can, usually in the cockpit
and or in the settee, rarely in the bunk.
As I said I'm not that experienced, just a weekend warrior at this point, but I don't think rolling at anchor is nearly as frequent as some would have you believe.
