Do not touch dolphins or reach out towards dolphins

Even we don't like being touched by people we don't know.

Precautions for Dolphin Swim


Pay attention to your surroundings

It's easy to get lost in the dolphins during the dolphin swim, but look around from time to time to make sure you are not separated from your group. It can't be helped to leave a little, but let's figure out where you are.

Many dolphin watching boats are crowded on weekends and during the season. If only one person leaves, it is difficult to find it from the ship, and it is dangerous because it may be hit by another ship.


Do not dive near the boat

If you dive near the ship, you will not be able to see yourself from the ship. move the ship without noticingIt can also be stowed away, so you don't hit your head on the bottom of the ship or get caught in the propeller when surfacing.Not necessarily. Never dive near the ship.


Do not go behind the boat

There is a screw behind the ship and it is very dangerous. Also, the captain cannot see it.

Do not go behind the center of the boat, including during entry and exit.


Do not go near the shore

Dolphin swims are done around the island, but if you get too close to the shore, the waves will keep you on your feet.

It may wash up on the shore. Also, in shallow water near the shore, people often hit their heads against rocks.

Beware of waves and currents and don't get too close to the shorePlease be careful.


Look up when you float

After descending, when ascending, be sure to look up at the surface of the water and check for obstacles.

Avoid hitting the bottom of the boat, getting kicked by other divers, or hitting dolphins.

be careful.


Do not hold your breath forcibly

Unreasonable breath holding can cause blackout (fainting) and is very dangerous. Be aware of your breath-holding limits during practice and do not force yourself to dive too long. As long as you can afford it.


Wave to the ship in case of emergency

If you feel cramped, have trouble breathing, or feel any danger, please let the people around you know and wave at the ship. (Out loud if possible) I will go to rescue immediately.

*Waving your hand on the surface of the water is an SOS sign. Please don't do it when it doesn't matter.


When the sea is rough

It is your responsibility to decide whether to enter the sea when there are waves or currents. Sometimes the guide or captain decides. Let's put safety first.

Measures against seasickness

The number one enemy of dolphin swimming is seasickness.

During the dolphin swim, stay on the boat for 2 hours per trip!

Usually, if you are not used to boats, it will be quite painful if you get drunk,Dolphin swim will be ruined.


Tips to prevent seasickness

◆Do not look down at nearby objects.

Most people who are vulnerable to seasickness are looking down and doing their best, but this is the pattern that makes them the most prone to seasickness.

Try to look as far away as possible.

I feel sick. The best thing to do is close your eyes.

◆ Quick attachment and detachment of equipment

You have to put on and take off your fins on a rocking ship.

If you slow down at this time, you will get drunk at once.

Practice getting on and off quickly with your own fins.

If you have little experience on a boat, be sure to take sickness medicine
