Our Vessels – The Industry’s Best


All crew are trained to Senior First Aid level certification as a minimum, and key personnel are trained in ocean rescue and in first response remote emergency medicine. We conduct regular training and drills in emergency response and practice safety at sea. 

All expeditions and tours begin with a comprehensive safety briefing to ensure you are fully informed about any procedures we will undertake and your role in them. We don’t just tell you that you are safe, we show you how we will keep you safe.  All vessels in our fleet exceed vessel survey standards and carry safety equipment above regulation requirements.


The beautiful Alison Maree is a modern, spacious and luxurious 20m catamaran, providing the ultimate in stability, comfort and safety. A long range expedition vessel purpose-built for the Southern Ocean she is immaculately presented, with three spacious viewing decks. Spend time spotting wildlife on the bow or from the huge upper and lower rear decks, or try all three! Inside, join the skipper in the comfort of the air-conditioned wheelhouse for the ultimate, uninterrupted 360 degree panorama. Downstairs, relax in the spacious and comfortable air-conditioned main saloon with seat-to-ceiling windows for uninterrupted wildlife viewing. Our gleaming galley is stocked with complimentary beverages and snacks. Quality finishes throughout including two modern toilets with washbasin facilities complete your comfort.

They ensure complete peace of mind and comfort to all passengers, and are especially welcomed by those that are not familiar with being on the ocean and those who do not swim well.

‘Indi Maree’ – Our Tender

Indi Maree is a 5.8m hornet wide-bodied tender vessel.  We are proud that she is powered by a 40hp outboard engine which has the lowest emissions rating on the market. Naturaliste Charters strive to make our tours accessible to everyone, and Indi Maree was purpose built with this in mind, including special loading capacity and safe handrails throughout for passenger transfer.

The ‘Pig’

Neither her name or her job are beautiful, but we are as proud of The Pig as any vessel in our fleet. We operate in stunningly beautiful but very remote locations with little or no infrastructure. We commissioned this service tender to ensure that there is no impact on our pristine operating environments when our vessels are refuelled. The Pig has electronic fuel pumps and is self-bunded, which ensures that even in the event of a spill it is completely contained and will never enter the ocean.
