When spending time out on the water with orca, it is important to respect their space - you are entering their environment. It is also important to research and follow laws and guidelines which govern how close you are able to get and how you should control your vessel around them - these are different in each country.
In Washington State, USA, there is a 200 metre exclusion zone for endangered Southern resident orca of the Pacific Northwest. In other words, you must not get closer than this distance. A boater in Washington State may face a fine for entering the exclusion zone around a group of orca near Orcas Island on Wednesday. Getting too close to these animals can disturb their natural behaviour, interfere with their communication and cause them stress.
