I seem to remember being taught to roll a few years back when I did that
kayaking course in the pool. When I mentioned the local canoe/kayak club to
my friend he said that he might join in order to do the pool sessions over
the winter. He has been sea kayaking for two years now and cannot roll. I
was surprised by this.
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.

My Capella and Explorer roll well. I have a WS Sealution that is a bit
tougher to bring up . The Aquaterra Chinook's we use are about the
same.
The Greenland / Broitish boats have a nice line for rolling up.
I think you have it right, if it is hard to put it over it is hard to
bring it back.

The easiest boat to roll is one that you fit in properly. Eg, I cannot roll
a polo boat. BUT this is because I fall out as soon as I go upside down
because it is not fitted to me and I can't reach the footpegs. I have
however rolled my I:3 (once, fluke, don't count it as being able to roll),
which is padded out around my hips and where I can press against the
footrest and the thigh braces.

I'm not a hard core paddler (or hard core anything else) but I can easily
manage the first phase of a roll anytime!

Here in Newfoundland Canada most hard core paddlers can roll a boat but
most paddlers are not hard core. I would guess that only 10% of sea
kayakers here have a roll; any roll!!!.

A Ha . Truth at last.
For the folks that paddle routinely on the sea and more for those
involved in white water I think most likely have some semblance of a
roll. BCU 3 star insists only on a knowledge of how a roll works but
does not go far past that and you don't need to complete an actual
roll. CRCA 1 in Canada is the same. Most paddlers I am sure don't go
far past this level.
Of the people I routinely paddle with most has a passable roll but the
folks I paddle with at night and on drop of the hat trips are not
average.
While white water is very different, I suspect the number of folks with
a roll is less than we think.

I've got a selection of boats to try and it is an interesting question. A
boat with a rounded hull is always going to be "easier" to roll. The
difficulty is stopping it rolling once you get back upright :-)

A flatter bottomed boat such as a Whippet/ Whiplash will roll steadily and
come up smoothly, and be stable when you complete the roll. My old Riot goes
over in two stages, and comes back up in two stages. The Wavesport Z is a
bugger it has as much beam as the average canal boat , and they don't come
up when they roll. In the Z it is a cert that you have to leave your head
till last and really make a last minute effort to come up. The EZ is much
easier. The Inazone is a doddle to roll, but it's low rear deck (with my
weight in it) catches easily so you need to be able to recover yourself
(especially with my low experience level).

You just need to adjust your roll to suit the boat.

Try a Valley Anasacuta... it has a hard chined angular hull and is
an absolute breeze to roll. Point being that you need to think of
relatively minor shape change with distance against major discrete
steps rather than just "rounded or not".
