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.
