How We Operate
Designed especially for whale watching, our modern catamarans are equipped with engines that minimise underwater noise and toilets that never pollute the sea.
Hamilton jet units are used for our vessel propulsion and are quieter for the marine mammals compared with other forms of vessel propulsion, they also have an internal propeller so the risk of a propeller strike with marine mammals is completely eliminated.
The main passenger cabin is enclosed and large outside decks offer great viewing and photo opportunities. Spacious air-conditioned interiors are fitted with comfortable seating while large plasma screens display our award-winning marine wildlife animations. Passenger numbers for each tour are kept well below our vessel carrying capacity to ensure your tour experience remains a personal one.
How do we find whales?
Sperm whales produce one of the loudest noises in the animal kingdom, to us it sounds like a series of rhythmic clicks or the ticking of a clock, but this click is actually one of the most sophisticated sonar systems on the planet.
Sperm whales use this sound to hunt, navigate, communicate and they can also use it as a weapon to stun or kill its prey!
It is generally pitch black where these whales are feeding, so they are not relying on their eyesight, they use echolocation instead, echolocation as the name suggests is location by echo. They send out a series of clicks then interpret the echoes these make when they bounce back from objects. This bio-sonar locates prey with great accuracy and provides a way for these whales to ‘view’ their world.
Our hydrophones (underwater microphones) can pick up the echolocation of a sperm whale anywhere from 1 to 8 miles away. The louder the click the closer to the whale we are, so if the captain is hearing the echolocation of the sperm whale and its quite faint we may need to make a move of 1 mile or more and hopefully on the next listen that ‘click’ should be a whole lot louder indicating that we are a lot closer to that individual. It is directional so whatever direction the click is coming from is the direction the whale is in.
