The plastic tube you use to breathe while snorkeling is called a snorkel. This comes in a few different styles, but dry snorkels and semi dry snorkels are the most user-friendly variants.
What is the purpose of a snorkel tube?
The snorkel is a flexible tube that allows you to breathe while you have your face in the water. You hold one end in your mouth and for air exchange to happen, the top of the tube has to poke out about the water’s surface.
How long can a snorkel tube be?
The length of a snorkel tube varies between 35 to 45 centimeters. The inner diameter is between 1.9 and 2.5 centimeters. For children, there are smaller snorkel tubes in length and diameter. The snorkel tube cannot be very long because of the lung volume, the water pressure, and the exhaled air in the snorkel tube.
What are the 2 types of snorkel?

Both have a splash guard at the top of the snorkel tube to help keep water out. With a semi-dry snorkel, some water will still get into the tube and you will need to expel that water. With a dry snorkel, there’s a device that moves to cover the opening so that no water gets into the tube.

Flex tube. Most dry and semi-dry snorkels will have a flexible tube, but even some classic snorkels have them too. The main advantage of flex tubes is that they give you the most freedom to adjust the positioning of the mouthpiece, which makes for a more comfortable fit.
Why are full face snorkels not allowed?

Snorkelling assists in increasing your lungs’ capacity to hold oxygen, as breathing through a tube is more difficult than regular breathing – think of snorkelling as a form of breathing exercise.
What should you not do while snorkeling?
Do not touch corals, fish or turtles. The only thing you can touch safely is sand and rock and water (that means with your fins also). Read our snorkeling etiquette page for learning how to develop skills for taking a break in the water without having to stand. Don’t use harmful sunscreen.
Can you go fully under the water in a snorkel?
Unlike scuba diving equipment, snorkels do not allow you to breathe deep underwater. Instead, snorkelers must exchange air at the surface of the water through the breathing tube. If the snorkel is submerged beneath the waterline, the snorkeler will not be able to breathe through the tube.
How long can you stay under water with a snorkel?

How deep of water do you snorkel in?
With snorkel masks, you can descend up to six feet underwater without issue. However, your snorkel mask may fill up with CO2 and make it difficult to breathe. As a result, you shouldn’t go deeper than six feet or even stay in the water for more than 25-30 minutes.
