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.

Don't worry, you'll never feel it.

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
group. Sorry.

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!!!!
