Hello Davej, you wrote:

No, my whole idea is to consider some form of handicapping device in
order to practice for a more difficult situation than you are going
to have in a pool.

Something I do for handicapping is to restrict the use of various
limbs in as many different water conditions as I can find. And of
course, practicing rolls without a paddle. This type of handicapping
is, in my view, more practical than trying to figure out how you're
going to fit your boat into the jacuzzi for aerated water practice.

If you think about the types of conditions that would capsize you,
it's good to think in terms of not just water and/or wind conditions,
but of your own potential condition as well. If you're in already
gnarly conditions that you can barely handle when you're feeling
great, what if you become injured? Might you then be more likely to
capsize in the first place? And still need to find a way to bring
yourself back up? Or, of course, end up swimming without the use of
a limb or two?

There are endless scenarios one can come up with to practice, and I
feel that all too often, we only think about practicing as if nothing
could ever happen to us physically, and ultimately, that's just not
realistic. There's always an exception to "bombproofness" lurking,
just waiting for the right moment to strike. Will we be ready? Or
at least as ready as we can be?
