According to the Australian Yachting Federation Special Regulations, the
definition of a "Monohull" is, "A hull in which the hull depth in any
section does not decrease towards the centre-line. All other boats are
considered to be Multihulls".

I am not intimately familiar with the M20, but from what I have read, it
sounds like it would (according to this definition) definitely be
categorised as a multihull.

Nonetheless, a very speedy looking boat indeed.

Because it had a tunneled hull the M-20 SCOW was considered the fastest. I
found the following at: http://www.m20scow.com/

The M-20 was designed in 1963 by Buddy and Harry Melges of Zenda, WI. The
M-20 is the only scow design with a tunneled hull and the original scow
with
a high aspect rig. The M-20 is an extremely fast boat that keeps it's two
person crew on their toes. The M-20 carries 175 square feet of sail in
it's
main and jib, plus a 250 square foot spinnaker for downwind speed. The
flexible and adjustable rig allows for crew weights of 270 to 450 pounds.
The boat is typically raced by two person teams including coed, two men or
two women. There are currently active fleets in Colorado, Indiana,
Michigan,
Minnesota, New York, Oklahoma, Texas, Wisconsin, and also in Ontario,
Canada.

The M-20 is a great all around boat with active fleets, a new builder and
a
healthy used boat market. Start a fleet in your area!

What is the fastest mono-hull (non-sailboard)on a windward leeward or
triangle course these days?

I estimate: 505, Intl 14 GP, 49er, 18ft skiff are contenders.
Since they all plane up wind, waterline is less of an issue so I would
guess larger craft like an E scow, and A scow are in this class.
