Now for the science bit. Which type of kayak is the easiest to roll ?

IM(not colossal)E the ones that are easiest to roll up are the ones that
are easiest to roll down to start with... Wider boats tend to be more
stable as you have to tip them over further to pass the Point Of No
Return, but once they do go then the same properties that kept them the
right way up before now help to keep them upside down...

Beyond that, boats with an effective brace point inside are, all other
things being equal, easier to roll up. I had quite a bit of trouble
rolling a Feathercarft because I couldn't brace myself well in it, and
the seat would move!

One of the easiest sea boat I've found to roll so far is the Valley
Anasacuta. It's certainly much easier to bring up than my Selkie, but
the Selkie is a very broad craft and much more stable to start with.
AIUI there was a flat rear deck version made especially for surf rescue.
The Anas is also easier to bring up than my river/surf boat, a Whip-It
where the hard edge on the hull makes it quite a bit harder than a BAT
to roll.
