Monohulls do not normally rock from side to side, nor do they heel over
30
degrees
unless you are racing. With the proper sail trim, they should not heel
that
much.

You seem to think I have not sailed monos- far from the truth. While on a
reach they have a fairly stable angle of heel, but I have been on many monos
where the famous "death rolls", which occur when running square, especially
in certain sea states, have been extreme. Not all monos experience this to
the same extent - hullform makes a difference- but 30 degree side to side
roll running square is not that uncommon.

You missed the point of the sails acting like a shock absorber in union
with
the'
pendulum action of the keel.


Not at all.


And what if you are on deck at the time?

Same as a mono in a knockdown.


And what do you do in this secure
section of the hull? Wait and hope for rescue because you won't be
able to
get yourself out of trouble.

EPIRB? While much more comfortable/secure than in a liferaft.


When a mono sinks however- dragged
down by that ballast that makes it self-righting- the only hope is a
liferaft.

Any boat that fills with water is going to sink.

Not correct- if buoyancy exceeds weight (eg foam cored multis) it doesn't
sink. The Rose-Noelle (a tri which capsized off NZ about 10 years ago)
floated for 100+ days until it washed ashore- all crew survived inside the
hull and walked to safety.

The idea about mono hulls
is that
they will right themselves before the boat fills with water.


The idea about multis is that their incredibly high stability means they
won't capsize.

Neither theory works all the time.



It depends on what you think is the most basic safety feature-
nonsinkability or self righting.

I prefer the self righting.

Each to his own.
