The answer is no -- you can teach students in a backplate, and you can use a long hose -- but there ARE portions of the PADI class that one MUST do while wearing a snorkel, so that has to be taken into consideration. We solve it by putting our OW students in 40" hoses. They donate the primary, but don't have to deal with pulling a hose over their head with a snorkel on.
And viz yesterday was actually MUCH better, Bob -- we're into the "whale snot" phase of this bloom, and I have high hopes for Saturday's dives!
