What an amazing tour. We saw whales, dolphins and porpoises. The crew was very friendly and enthusiastic. We could really tell they are very respectful towards the animals, we were able to see two humpbacks for nearly half an hour, everybody was silent, the engine was off and the crew was also in awe. Only when the whales left, the engine was back on and we also started moving again. We really felt like we had all the time in the world and we didn't disturb the animals.
