Saying “No” to Single-Use Plastic

Aboard El Aleph you won’t find a trace of single-use plastics. To maintain our commitment to sustainable luxury we have sourced alternatives to ensure a plastic-free experience. Rather than plastic bottles we use re-useable drinking bottles, stylish glass straws add a touch of class to our cocktails and even the trash liners onboard are made from biodegradable natural cassava.

Our plastic reduction initiatives do not stop there, once onboard El Aleph you’ll find your very own reusable water bottle and dry bag. We hope that you will take these items home with you to remind others of how to reduce their own plastic use and preserve our oceans.

Ocean Fish, Not Reef Fish

Indonesian waters are teeming with fish. El Aleph serves sustainably caught, open ocean fish and does not take from the reef.  For those wishing to try their hand at deep sea fishing, we can arrange trips to areas outside of the national parks, where fishing is allowed.

Locally Sourced, Sustainable Produce

We recognize that we are in a unique position which enables us to interact with, and work with, local people from across the archipelago. When purchasing produce we aim to use the highest quality, locally sourced supplies to support Indonesian farmers. This means that dining onboard is an experience which is bursting with the freshest flavors of the tropics.

Coral Reef Aware Cruising

Our crew of experienced seamen have years – sometimes generations –  of sailing the waters around Indonesia; their local knowledge, combined with El Aleph’s advanced navigation technology means that they are able to maintain a safe distance from the coral reefs at all times. El Aleph never drops anchor in water less than 40 meters deep, and whenever possible, at least 60 meters. To protect the reefs from accidental damage El Aleph utilizes small tender boats to make trips to shore and to access the reefs for diving and snorkeling (see title image above).

Sustainable Waste Management

El Aleph strives to reduce waste, recycle and dispose of waste responsibly. All of our tin cans are recycled and waste is sorted prior to disposal onshore. El Aleph does not dump any solid waste materials into the ocean.

Marine Research and Collaboration

Our highly skilled crew, many of whom have been with us since our launch in 2009,  are passionate about the marine environments and we are involved in ongoing collaboration, gathering information about marine life and marine environments for experts seeking to better understand the conservation management needs in the Coral Triangle.

El Aleph contributes to marine research expeditions with Planet Deep and The Oceanic Society.  During these research cruises, El Aleph crew ensures that the fortune ate onboard scientists are looked after in traditional El Aleph style, luxury cabins, exquisite dining and full logistic support. This is, after all, what El Aleph does best. The findings from these expeditions give scientists a better understanding of cetacean migrations and behaviours in some of Indonesia’s least understood areas.

Planet Deep, is an Indonesian non-profit organization which enables scientific research through conservation tourism in the Coral Triangle – the global epicenter for marine biodiversity. Co-founders Benjamin Kahn and our cruise director Johannes Hennicke have scientific expertise and a wealth of knowledge concerning Indonesian waters – all of which they pass on to our team.

El Aleph’s collaboration with Planet Deep allows us to contribute to marine research and conservation


El Aleph’s collaboration with Planet Deep allows us to contribute to marine research and conservation benefiting cetaceans, oceanic mantas and the amazing gentle giants – the whale sharks.

El Aleph’s crew are the only liveaboard crew in Indonesia that have the benefit of working with these two cutting-edge conservation organizations, implementing the knowledge and skills that they have learned from the experts to ensure that you and your family enjoy a more meaningful cruising experience.

Indonesia offers some of the most pristine reefs and natural environments on Earth. It is one thing to enjoy these wonders of Mother Nature and another thing to feel as though you are contributing and giving back to the planet we call home.

So many regions of Indonesia are unexplored and there are marine species still waiting to be discovered. Research which leads to a better understanding of the environment leads to breakthroughs in science which can affect all of us on a day to day basis.

We are extremely excited about our upcoming collaborative initiatives with Planet Deep and we will be making announcements shortly!
