Sounds to me it is YOU who know nothing about sailboats, Mr. Long.

Most amusing. If he met Einstein, he tell him he didn't know anything
about physics......or mathematics.....

This tells me you never sailed a well designed sailing vessel.

Only about 20 or 30, lost count long ago but there have been Cals,
C&Cs, Swans, Baltics, J-Boats, Custom Frers and Ron Hollands among
others. Most of them were well designed but some better offshore
than others.

They are all different but dead down wind in big following seas is
rarely a stable ride.

That's an invitation to a violent broach in any kind of wind.

Thanks Jere, yet more proof that Wilbur/Neal is a little short of
experience.

Cheers

Indeed, as the your rudder rises out of the crest, which is alread
flowing with your direction of travel and rendering the thing useless,
and then the wind or you boat moves just a bit and you now present you
sheeted and flattened main to the wind...... smack!

Dead downwind sailing under spinnaker and sheeted flat main causes
little or no rolling in a properly designed sailboat such as the one I
sail. Sailing with quartering wind and seas makes for a VERY rolly ride
as the vessel yaws and slews as every wave overtakes her.

You really don't know chutes, either. I regularly pass those going dead
down wind. The absolute easiest ones to pass are the yahoos who flatten
the main, making it nothing more than drag and disturbance in the
airflow. They over-sheet the chute so it can't collapse.... might as
well have a bedsheet up for all the good it does. [The luff of a chute
should be curling, but not curled, at all times to get speed.]

Cracking off 15-20 degrees, the ride improves greatly as both sails are
on the same side, limiting the roll considerably. In addition, it's
faster; the distance increases by 5%, but VMG improves with the
increased apparent wind. The autopilot (hey, I'm cruising) more easily
handles waves on a single quarter rather than both, so I can leave the
steering to Otto and have fun playing the sheets.

Thanks. I don't claim to be an Einstein but I have built a career on an
understanding of rythmic rolling. In fact, the University Oceanographic
Laboratory Organization has my discussion of the subject on their web site.
Possibly interesting reading for one of the two or three people with enough
money left to be thinking about having a trawler yacht built.
