Why do you say that? I'd say the foretriangle matches the mizzen quite
well. If the C of E of the main matches the CLR (as it should for a
balanced ketch) then she will balance under miz and foresail.

Sure.... any ketch that doesn't balance well under
jib & mizzen. It doesn't happen automagically,
y'know.

I can't say firsthand, but I suspect that Mari-Cha
4 doesn't balance at all under jib & mizzen. So
there!

Lots of forces in play here, Navvie©. The horizontal distance (in two axis
as the boat heels) between the sails CE and the boat's CLR, the torque
developed by the hull & foils, etc etc.

If you're talking about Mari-Cha 4, it looks to me that the mizzen is far
bigger than the foretriangle.

balanced ketch) then she will balance under miz and foresail.

Sure.

"In theory there's no difference between practice & theory. But in
practice, there is."

Not all ketches balance the way they should. Possibly due to different
priorities on the part of the designer, possibly by error, whatever.

I'm far from being a Ketch Expert but it does seem to me that I've seen
more reduced sails on Ketches with reefed Main and doused Miz

The forsail and mizzen are more a Yawl set-up

For what it's worth (Not much) that seems to be the way I've seen it

OT

The tri sail track is to avoid unbending the main as you suggest. Double
reefs are not sufficient. You need a deep reef at least and a trisail
and storm jib are best for ocean crossings.

In a storm would you, if you had a ketch:

1. reef down the main and mizzen, drop the jib.
2. use just a tri sail on the main mast.
3. use a storm jib and a reefed mizzen.
4. just use a storm jib.
5. Use just a reefed main
6. Use a reefed main and a storm jib.

And why is a tri sail track offset on the main mast?

Is it just because you can raise the sail fast without un-bending the
main, or does it have something to do with shape.

How much, if any foil shape should a tri sail have?

And how do you best figure what size tri sail you should use?

And with a quick double reefing system, do you think a tri sail is
needed?

Thanks

One cannot give advice with out knowing a bit about conditions. Wind speed,
wave action, local conditions, lee shore ect.
