If you want to really enjoy the great water surfing encounter, then you want to become able to breathe though floating to the water and maybe not have to lift your face to take a breath of air. That's where the snorkel arrives into play. When we had our noses and also mouths over the back of our heads we wouldn't need snorkels, however since we usually do not we desire snorkels; unless you want to swim around in the back.
