El Aleph


40m / 5 cabins / 10 guests / 13 crew

El Aleph was built with the spirit of discovery at heart. This broad beamed yacht’s structure is based upon the ancient phinisi ships that carried spices across the islands of Indonesia, though with interiors handcrafted over 200,000 hours by skilled cabinet-makers in Bali, her interiors offer ample comfort and modern technology.

Unusually, El Aleph features a “quiet” mode whereby she is able to cruise for extended periods of time using electrical power with engines shut down. What’s more, she’s one of the only boats in the region offering rebreather dive equipment, making her an excellent choice for advanced diving aficionados.

El Aleph cruises between Indonesia and Malaysia, with routes including Komodo National Park, Southern Thailand, Langkawi and Burma. Her experienced crew of 12 includes a cruise director, a dive master, and a chef.

Onboard Experience

El Aleph features five air-conditioned en-suite guest cabins and an additional single cabin. The spacious master cabin is situated above deck and leads out onto a private terrace on the bridge deck, while four double en-suite guest cabins are situated below deck. An additional bunk cabin is ideal for extra guides or a child minder.

Beautifully crafted in century-old teak and ironwood, El Aleph’s interiors are a sight to behold, Inside, a lounge, library and dining area are decorated in warm wood tones and crisp white fabrics with hints of vibrant colour. Outside, a large open deck features an additional dining and lounge area for relaxing alfresco, while there’s ample space to recline on the bowsprit.

Onboard facilities include air-conditioning and wifi, TV & DVD, while water sports equipment includes sea kayaks, a wakeboard and a bodyboard, snorkelling and dive gear (including nitrox and rebreather) and fishing equipment.
