Cheap And Nasty Snorkel extension
Good point. So you need to "in through the mouth out through the nose" or else get a "proper" mouthpiece that expels the "out-breath" directly. As for the pressure, that's a big question mark. At the prop, I'm only under maybe a foot (depending on body position). I don't know if the pressure would be too much for me to take a breath or not (it's easy for me to create suction in my mouth at this depth, so...I donno.) After all, look at all the Bad Movies that have Our Heros hiding underwater with a reed in their mouths...

When you exhale you will fill the long tube with your expelled air and then breathe it all back in. I believe this would result in hypoxia (oxygen deficiency) in which case you could drown without realizing what's happening. Snorkel tubes are short so most of the exhausted air is expelled and there is enough of an influx of fresh air to avoid this problem.

But I've always wondered: why not rig up a hose arrangement to be able to breathe? We're not talking 50-ft depths here, so I'd think it would be pretty safe. Perhaps some kind of non-collapsable hose on the end of a snorkel? Does anyone do this? Why or why not? Lloyd Sumpter "Far Cove" Catalina 36 |
