- Accommodation
- There are two cabins on the lower deck with spacious double beds up to 1,60 m wide and wardrobes. Large hull windows provide natural light and the feeling of space. Thanks to a large, well-finished bathroom, all guests will have high on-board comfort.
- Galley
- An innovative galley on the lower deck is equipped with a sink, oven, gas hob and many storage systems, while the 130-litre fridge and freezer are hidden under the co-pilot seat. Solar roof panels make it possible to use them for long periods, far away from shore power. The boat has a uniquely sliding door with a retractable section that connects the galley to the cockpit in a social and complimentary way. It lets the chef cook while connecting with the rest of the guests in the cockpit. Moreover, this layout lets in plenty of light and good ventilation to the lower deck, and the locking door can be used as additional safety protection during the night.
