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



Indeed, as the your rudder rises out of the crest, which is alread flowing

the wind or you boat moves just a bit and you now present you sheeted and
flattened main to the wind...... smack!

You and the other dumb naysayers here clearly lack understanding of basic
laws of physics.

With the chute pulling the boat by the bows and lifting the bows the rest of
the boat is just along for the ride. It's highly unlikely that the rudder is
going to come out of the water when running - even when a wave crest
passes - as there is such a thing as a quarter wave that becomes quite large
at hull speeds.

I can tell you people have rarely or ever sailed on the open seas using a
spinnaker because you obviously don't know what happens out there. You don't
have choppy little seas you find on your little bays and inland lakes that
can raise the stern out of the water enough to disengage the rudder because
of the teeter-totter effect of short wavelengths. Instead, you have large,
long period waves with crests that are not breaking or anything close to
breaking unless you're sailing in a gale and those who sail in a gale under
spinnaker are crazy.
