If we meet dolphins and if we want to take a close look at them, then...

The International Regulations approaching cetaceans point out :

• Reduce the boat’s speed below 7m/hr.
• Since you know well the sea area, it is highly important that you shut down the depth-finder, the sonar, fish detectors or any other apparatus that is producing supersonic vibrations (<500KHz).
• Approach cetaceans sideways, never from front or rear.
• In case the boat has accidentally run into their course, it should change direction with a manoeuvre and move parallel to them.
• If you see that they have calves with them, it is better to avoid any kind of encounter and stay in a distance, about 150 meters away from them.
• Lob tailing (tail slapping) and tail-sweeping on the sea surface is a sign that they are distressed.
• If you encounter a group of "adult" cetaceans, the permissible approaching limit is 50 meters.
• Remain in the same direction. It is at the dolphins' disposal to approach you. In this case, slow down and maintain a steady direction.
• Occasionally, they need company and they remain right next to the boat. Then, you are completely lucky.
• Stall the engine completely or tick over.
• To continue your trip, augment speed slowly and leave the sea area without abrupt manoeuvres.
• It is forbidden to feed them or caress them.
• You should be specially trained to swim with them.
