In the 1800s they could
certainly make watertight plank ends.

Is that a fact? Try looking up the history of caseinate glues.

But "glue" isn't necessary to make a watertight joint. Ever hear of "caulk"?
Shucks, well made lapped planks don't even need that.

In other words.... Jax, you're just plain wrong about this. Sorry, I tried to break
it to you gently.

dougie, engineering genius that youare what with all the reading of college
physics and engineering textbooks you read, should know that the end of planks
are under some considerable stress and strain as the hull works in the seas.

I know you don't believe you are stupid, but everyone else believes you are.

So tell me Jax, how come it is that almost all ships were double ended below the
waterline? I mean from Hanseatic cogs up through the clipper ships, coasting
schooners, etc etc?

Yes, planks come under strain at sea. So you are now claiming that nobody ever
built ocean going ships until carbon fiber & epoxy (or at the very least,
carbon-nickel steel & arc welding) were invented?

There you have it folks! Jax displays his "genius".

Read his post again, if you don't understand what I mean.
