not for the volume, not for the bouyancy.

A canoe stern, or almost any double-ender type stern, is
better triangulated than any transom.

The canoe stern is hardly unique to Valiant.

It also follows very old design ideas.


the design dates from when it was impossible to build a boat with a watertight
meeting of the ends of planks. Therefore, if one bent the planks around and up
so that they met above the waterline, you didn't have to worry so much about
taking on water.

A good point, but Doug won't like it.

so, making a transom (that doesn't break) 10 times stronger is a *benefit*?

Sounds like a disadvantage to me. Extra cost, extra weight, slower boat speed,
all to fix a problem that doesn't exist.


That must explain why there's no such thing as hull speed... structural strength
can be zero because they never break... that means boats can be weightless!


Good lord! It's like a discussion with an imbecile.

We are not talkng about optimal racing designs as much as why a canoe
stern is not that great except for people who expect to have to stop
sailing in storms.

But you you can't argue with an expert of triangulation!

Oh that's a real benefit. I guess Doug must be saying that yachts often
sink from their transoms falling off. Hahahhahahahaha."

How far back was this, Jax, the Vikings? In the 1800s they could
certainly make watertight plank ends.

Does your Scientific Sailboat Training include marine archeology now?

(among other things)
canoe sterns have less reserve bouyancy than transom

Correct, Jax. Very good!

.... one of the bigger
complaints re canoe sterns

Uh-oh, you better talk it over with MC. He says that reserve bouyancy
isn't an issue because it's the transom that keeps out big scary waves.

Yes please do.

Also, be prepared to explain why _your_ explanation disagrees with the
explanation of the professional naval architects who devised this measure.
