Handcrafted with the spirit of discovery at heart, El Aleph was inspired by the phinisi trading ships that carried spices across the islands of Indonesia.

She was built to the highest standards as an owner’s yacht, constructed with fine teak, finished by skilled carpenters, alongside modern technology. El Aleph’s owner still spends three months a year aboard.

One of the only boats in the region offering rebreather dive equipment and Trimix, making her an excellent choice for advanced diving aficionados, or for leisurely cruising.

El Aleph cruises the entire Indonesian Archipelago, with routes including the magnificent seascapes of Komodo National Park, Raja Ampat, Alor and the Spice Islands. Her experienced crew of 12 includes a cruise director, a dive master, and a chef.
