If the apparent wind, say, decreases *any* resistance by, say lifting
the boat a fraction, or changing the effective hull shape that is
hitting the water, then NORDHAVN's statement is technically correct.

Poppycock! NORDHAVN's statement is fiction. Pure fiction! Had they said
light air instead of dead air they would have been correct on any point
of sail other than with the wind dead ahead but they didn't say that.
They said dead air which means NO WIND. No wind will always cause the
apparent wind to be from dead ahead when motoring ahead and this dead
ahead wind can't impart any forward force to the boat because it can
only shake the sails around and cause drag on the sails and rigging
which slows the boat.

Any chance they have some type of special rigging or innovative hull
shape to make what they are saying true? Ever seen what a dead air wind
dead ahead can do for an airplane?
