Expedition and trawler yachts are designed primarily to provide maximum comfort underway, while also offering extended range. They feature robust hulls, including designs suitable for open-ocean cruising, increased fuel capacity and a high level of onboard comfort, providing reliability and safety for guests. Vessels over 40 metres in length typically offer an even greater degree of autonomy, with more extensive equipment, storage areas and refrigeration capacity, as well as backup and redundant systems for essential onboard machinery and systems.
