If sailing with your boat in Spanish waters you are lucky to see a group of cetaceans and you want to get closer, you have to do it smoothly, at a maximum speed of 4 knots, from behind and at an angle of 30º. During the observation, a parallel trajectory must be maintained, without abruptly changing speed or direction, defined by the Royal Decree 1727/2007.


This Law defines the concept of mobile space for the protection of cetaceans, which is the perimeter of an imaginary cylinder that includes marine and air spaces with a radius of 500 meters, with a height of 500 meters in the air space and a depth of 60 meters in the marine space, around the cetacean or group of cetaceans. Within the mobile space for the protection of cetaceans, no activity can be carried out that could kill, damage, annoy or disturb the animals. Specifically, you cannot:

- Physical touch the animals, both the boat and people

- Swim with the animals
- Throwing food, drink, garbage or any other solid or liquid substance that could harm them.
- Prevent them from moving freely.
- Separate the group of animals.
- Produce loud and shrill noise and sounds to move closer or further away.
