Re: [Paddlewise] Breathing tube

Actually it is not the length of the tube so much as its volume as compared
to the volume of your lungs and your normal breathing.

however a real wide tube i.e. as big as a house gets a lot of air mixing,
so that's why people often use the 1 foot as a rule of thumb based on the
assumption that a snorkel just wont be more than an inch or two in diameter
