Skippy's probably running to keep the rolling to a minimum.


Ah ha. A statement that makes me wonder if Neal has ever untied his
bananna boat and taken it to sea. Most sailboats I've been to sea in roll
terribly dead down wind since there is no side force to damp rolling from
the wave excitation that is still present and the eddies of wind off the
rig create large rythmic rolling forces.


While I am definitely not familar with the rolling moment of Skippies Pig
and it could be significant I was hoping he had sense enough to purchase a
boat that did not suffer from excessive rythmic rolling and knew how to sail
it to minimize those effects. But, that may, indeed, be hoping for too much.

Sounds to me it is YOU who know nothing about sailboats, Mr. Long. It also
sounds to me that you don't or can't use a spinnaker. If you sail downwind
wing and wing there can be significant rolling. But, if you use a spinnaker
like I do and sheet the main in flat there is very little rythmic rolling
when I run. Another consideration is the underbody of the yacht. My fine
blue water yacht just happens to have a Scheel keel which is also quite
shoal. It's the deeper fin keels and traditional full-length keels that
contribute to a rythmic rolling effect when running much more so than a
shoal draft vessel. This is due to the lift generated by the extra leverage
of a deep draft underbody.

I have sailed considerable periods of time running and I can tell you
rolling is barely there under a spinnaker. Rolling (and yawing) increases
greatly when sailing with the wind and wave on the quarter. The large, long
period waves tend to slew the boat all over the place as they strike the
quarter. A wave coming directly from astern does not slew the vessel at all.
And a spinnaker pulling the vessel along by her stem head gives the vessel
no cause to roll.

Those sailors who complain about excessive rolling with boom end dipping
into the water when running sail ill-handling boats and that's a fact. My
boat is not to be counted among those less well drawn.
