Special considerations: Sperm Whale

Whale watching for sperm whales requires extra caution, since sperm whales have a great need to relax on the surface to breath sufficiently and get ready for another dive
Reduce the speed to 5 knots in areas where sperm whales are present
The sperm whale is often first spotted by its blow that can be seen from several miles away. The blow is unlike that from other whales in many ways, but especially because of the direction which is angled forward. In this way, it is also possible to see the direction the sperm whale is traveling
First you check the course of the sperm whale, then adjust the speed gradually upwards to a maximum of 10 knots if you are more than 1000 metres away
Begin reducing speed when you are 1000 metres away from the sperm whale
When directly behind the sperm whale, position the boat according to the whale’ position and course. When 300 metres behind the whale, the gear should be set in neutral and the steer carefully to follow the sperm whale
There should not be more than 2 boats (no matter the size) near each sperm whale at any time in the observation zone
If a sperm whale shows signs of disturbance (suddenly changes its orientation or makes shallow dives approximately 1 to 5 minutes without lifting its tail), one must leave the sperm whale alone
One is not to stay with the whale for more than 3 consecutive dives
Except from the points stated, all other guidelines also apply
