There are occasional sea patterns that are uncomfortable on a multi,

reach max stability at about 5 degrees of heel (when a hull lifts). As
this
never happens on cruising cats, all heel angles are less than 5 degrees.
Short sharp waves can occasionally exceed this a little due to the hulls
being in a trough and crest. Compare to a mono rolling downwind where
heel
angles can be 30 degrees side to side.

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

You're right, but they can in sudden gusts with a relatively inattentive
cruising crew.

Multis do have a different motion- shorter and sharper compared to slower
but much more amplitude on a mono.
Personally I find it quite comfortable. As stated in a previous post a
glass
never spills, which is a significant observation on the severity of the
motion.

When a multi capsizes it floats- most are now equipped with hatches to
enter
a secure part of the hull in a capsize.

And what if you are on deck at the time? 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.

Well, the same argument can be made for a mono if you're on deck and she
heels dramatically or takes on water suddenly.

Why would you be unable to get yourself out of trouble if you're fairly
secure in a hull?

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

Not completely true, as most modern cats will not sink. Of course, never is
an absolute, so I suppose it's possible though remotely so.

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

I prefer the self righting. At least I have a chance to recover and
continue

sailing, in that case. If it sinks, then the life raft is your backup.

Many who sail cats don't carry a liferaft, because the cat or tri is the
liferaft.

Now I'm not claiming that a multi is the end all and be all of safety at
sea, but most of the time, the prime consideration is crew durability, not
boat durability. Crews get tired on a boat that's heeled all the time for
long distances. Tired crew make more mistakes.

Well, you're certainly not a licensed captain. I suppose you can call
yourself whatever you want, but the typical definition is licensed by the
USCG or other authority.
