What defines acceleration in a boat?
 

DSK suggests that a Mumm30 "accelerates faster than a beach cat". Now
while that may or may not be BS it raises an issue. if you wanted a baot
to really accelerate well what sort of rig should it have? What about
SA/D? What boat(s) have the highest SA/D and are viewed as 'rockets'?

What defines acceleration in a boat?
 

Acceleration as felt on a boat is a direct function of
how rapidly she gains way.

To feel the most acceleration a sailor needs to have
maximum sail area to displacement ration.

In my vast sailing experience I can say with surety that
the most felt acceleration is that which occurs on a
sailboard in high winds when one can go from zero
to thirty or more knots in about three to five seconds.

No other sailing vessel can claim this acceleration.

And hyrdrodynamically ideal wetted surface which is a 3rd factor.

Could this be true? A sailboard gets to 30MPH faster than a Mustang or Saab
Turbo? 0-30 in 3 sec is pretty fast.

Probably not Cappy, but when 6 tonne of boat starts that slide down
the face of a big ocean wave....nothing else in sailing compares to
the thrill.

Boats don't slide.

How about a 4.8 tonne boat doing the same thing?

Normally I would take this as a challenge to see if I could work out a physics
problem using skills untested for 30 years. But tonight is my Bible Study

What a strange question.

If you've done it, then I find it difficult to understand how it wasn't one
of the biggest thrills of your life.

Oz has mentioned the whoops and cheers. That is exactly what I have
experienced. Once the boat gets over 14 kts *everybody* begins to shout.
Even the inexperienced crew will love it .... unless they don't have total
confidence in the skipper!!!!

Perhaps you might like to read some accounts of people caught in storms?
They don't describe elation afterward -more often great relief at having
survived.

The trouble with storms is, although they can be fun at
first, if they last too long they become intimidating because
all senses are assaulted. There's the constant noise, the
chaos of motion, the wetness, the strain on the gear, the
doubts that the gear will last, the choices that all must
be made correctly and in good time. I think it would take a
raving lunatic to actually enjoy a storm that lasted much
more than a day. Such a man would enjoy several days
of Chinese water torture.

Maybe we are talking about different things. I'm talking about going
downwind in an F8. Going upwind in an F5 can be unpleasant. Going
downwind in an F6 can be unpleasant, unless you have the right crew.


Going downwind, at speed, with the right crew on the right boat, is a blast.

A boat in the water in not capable of sliding. Look it up. Boats do not "slide"
through the water.

Actually, the do in the right conditions. This even happens in the
"protected" waters of the SF bay. There are pictures to prove it
in Lat. 38, and I have a racing friend who was on a boat when
that happened.

What defines acceleration in a boat?
 

The term knots per hour is used in defining acceleration. Bit of trivia
knowledge I learned once upon a time. Actual Speed is Nautical Miles Per
Hour (relating to the water or relating to the ground). The other
definition is: "Depends on whom I'm after . . .or trying to get away
from.!"

Never heard of the downhill slide...it's a sailing term.

I've also heard of boats "heaving" which they don't do either.
