Having a double-ender here I cannot confirm they are any more seakindly than square stern boats. I have sailed a couple of normal boats like the J, Bavarias, Hallbergs, Jeanneaus, etc..
What I can confirm is that some square stern boats, esp so called reversed transom with big transom area get a kick from a passing roller that can send the boat surging forward much faster than you might like it.
So, with a pointed stern, you do not get the kick of acceleration, but you are much more likely to get pooped - because you will have relatively less displacement
HCh has solved
this problem neatly by designing a pointed AND raised stern AND small cockpit
volume - probably the way to go (but it cannot be retrofitted ;-(((.
In any case, I would avoid extreme flat and square sterns in any boat that will not plane easily and safely.
