Dealing With Defective Defectors

CBS's 60 Minutes proved the exception last month when it disowned part of a
two-year-old story. On March 3, 2002, the newsmagazine profiled Ahmad
Chalabi and his Iraqi National Congress.

"Hull speed" is voodoo science
 

utter lack of understanding on your part gould. you are trying to force fit
garbage science into a unified theory of the universe.

IMO, a Hobie Cat is on plane....(hell,
sometimes airborne)..when it is making better than hull speed.

Hobies have DEEP Vee hulls, not possible to plane.


Normally laden, all but a few inches of that
"Deep Vee" is above the waterline.

What's the effective draft of a Hobie Cat, in inches?

One could make a case that the boat is always, (effectively) on plane at
least
as easily as a case that it cannot plane at all.

The exceptions prove the rule, as always.

one the hull goes through the wave, what prevents another from forming
just ahead? .... or does one? Is this like breaking the sound
barrier, where one leaves compressability issues behind?

that has *nothing* to do with "climbing the bow wave.

ah, duh. makes sense to me. doesn't it?

[grin]

Who cares what hull speed is? If you're having a good day on the boat,
what's the diff how fast you're having fun?

It is, of course, though many ignorant people will claim they read it in a
book, so it HAS to be true.

"Hull speed" is voodoo science
 

There are hull forms that are not bound by their own wave train, or
are bound to a lesser extent (such as long skinny hulls).

no hull is "bound by its own wave train". none.

induced drag imparted from
converting motion into wave trains.

bull. that is not what induced drag is at all. check your terms.

"Hull speed" is voodoo science
 

as speed increases wave making becomes
the dominant factor in a non-planing hull.

bull, induced drag goes up at the cube of boat speed and has nothing to do with
waves at all.

"Hull speed" is voodoo science
 

For an average
displacement hull the tradional equation works fairly well at
identifying the approximate crossover point, where considerable extra
power is required to go any faster.

bull. most every recreational sailboat made in the last 40 years regularly and
rather easily exceeds the speed predicted by "the tradional equation".

"Hull speed" is voodoo science
 

for what, mark? for what?

Thanks Wayne.

You're quite welcome. Hopefully I didn't belabor the obvious.


no, you didn't belabor the obvious. you did belabored erroneous, voo-doo
science as written by writers plagarizing other writers who plagarized others
who took to heart a silly, yet scientific sounding, explanation given to 19th
century British naval brass who couldn't understand why doubling the power to a
boat of the time didn't double the speed of the boat. the brit brass dumbly
nodded their heads and proclaimed to the Queen that they had the fastest boats
on the planet.
