S/V “Promethee 2” is a Nautitech 46 Open catamaran, 2016 model, first sailed in March 2017, for sale by owner. The Nautitech 46 Open is known for its sailing performance and cruising comfort to which we can abide.

We are a family of five who set out with the intention to circumnavigate, but plans had to be changed. The boat was therefore equipped accordingly and is totally off the grid. It is self-sufficient in electricity with 2400 W new solar panels, 900 amp Lithium batteries, with a 5000 W Victron quattro inverter/charger. There is of course a water maker, 7 kg washing machine, induction cooking plates, electric oven and ice cream machine giving the comforts of modern living. The new main sail and genoa from North Sails, along with the 98 m2 gennaker give the boat top sailing precision, simplified with the two electrical winches.

All the running rigging goes back to the cockpit enabling sailing single handedly and safety at sea. A new radar and the large 12 inch chart plotter was installed in June 2023 which simplifies navigation. The new 25 hp outboarder provides for exploration at sea and fun water activities in the 340 UL Highfield dinghy.

The boat has 4 comfortable cabins and 2 spacious forepeaks catering to 10 people if desirable. There are 4 heads with electrical toilets and two showers, where the starboard shower has been turned into the washing room. This shower can easily be converted back to its original use. The four cabins and saloon have air condition. The cockpit has full canvas covers and a bimini over the trampolines providing delightful shade. The boat has recently been hauled out to have new anti-fouling and polishing of the hull. The boat has had several other upgrades. See inventory for specifications.

The Open 46 was created to meet the expectations of today’s travelers who are looking for a true sailing experience without sacrificing comfort. Whether you are planning a few days at sea or a round-the-world trip, this luxury yacht will take you to the most beautiful spots in the world while your family and friends are enjoying pure comfort in a beautifully designed interior.

The innovative concept of the Open 46 catamaran is based on a sleek and elegant design. The living room and the cockpit have been merged to gain space – it’s the essence of the “Open” concept. The living room of the Open 46 offers beautiful volumes, like an invitation to enjoy daily life in an amazingly elegant and warm atmosphere. The interior is chic, made of  wood, beige textiles, and with bright natural light and details in stainless steel.

We are currently living on the boat which is located in Cartagena, Colombia, and we plan to sail over New Year’s for Panama. We are flexible when it comes to the date and location for the transfers of the boat.
