Not because I am PADI, not because I have an equipment fetish- but I have been adrift in heavy seas for prolonged periods- I always stuff a collapsable snorkel in my BC. Snorkels are standard gear for military rescue swimmers, let's all do the math. It's a survival tool.
I can see it being usefull in some situations if you are out of air and in heavy wash. Typically I do not dive in that heavy of conditions, the boats won't let you. Of course, conditions can change on the quicky so I guess better safe than sorry.
