What is the Optimum Length of a Snorkel? The maximum length for a snorkel without compromising safety is 16 inches. Again, therefore a garden hose at a minimum of 25 feet in length would be considered unsafe: 25 feet is way longer than a traditional snorkel’s 16 inches!
Why is there a limit to the length of a snorkel tube?
A longer tube would not allow breathing when snorkeling deeper, since it would place the lungs in deeper water where the surrounding water pressure is higher.
How do you snorkel longer?
When you are ready to swim, bite down on the plastic mouthpiece of the snorkel and close your mouth around it to keep it in place. You can also wear a life vest, as this can help you stay buoyant in the water and swim for longer without tiring.

When you dive deep into the water, your diaphragm is being compressed by all of the water around you. This, in turn, prevents you from being able to take a breath of air. … That is what it feels like to dive too deep with a snorkel.
How far can you snorkel?
The maximum length of a classic snorkel goes up to 16 inches. This limits the depth that the snorkeler can travel to one meter. If the person goes any deeper, the water enters the tube and stops the air, making it impossible to breathe.
Can you breathe underwater with a long tube?
If you had a long tube extending to the surface and tried to breathe through it from a depth of 10 meters or so, you’d have a pressure differential of one atmosphere to worry about. It’d be kinda like sucking on a perfect vacuum. You will be able to exhale, but not inhale.
Can non-swimmers do snorkeling?

How far underwater can you breathe through a hose?
You can only go a few feet under water before you’ll no longer be able to draw air into your lungs through that hose. It’s a pressure problem. The water pressure outside your chest increases rapidly as you go deeper, but the air pressure inside the hose and your mouth barely changes at all.
