Our New Hybrid-Electric Catamaran (HH44 full tour)

Key insights


Today marks the 1-month anniversary of moving aboard their new boat, named "Curiosity", emphasizing their passion for exploration and off-grid living.


Curiosity is equipped with off-grid capabilities, including solar panels, hydro regeneration, rain capture, lithium-ion battery bank, and hybrid electric motors, enabling them to reach remote destinations.


Despite the high-tech systems, there are still challenges to overcome, including optimizing the hybrid drive system and improving motoring speed.


The boat includes a dedicated workshop area for projects, a testament to their self-reliance and the importance of having a functional space for maintenance and repairs.


Living on Curiosity involves a significant learning curve, adjusting to new systems and sails, underscoring the ongoing journey of adaptation and growth.


Their tender, an OC tender with electric jet propulsion, demonstrates their commitment to efficiency and environmental consciousness, even in selecting accessories for Curiosity.


The integration of modern technology, such as a fuel polishing system and advanced electrical setups, shows their focus on reliability and sustainability on the seas.


The thoughtful design of living spaces, including the galley and cabins, reflects a balance between functionality, comfort, and the joy of living at sea.


The choice of fresh water over seawater toilets and the inclusion of amenities like air conditioning and a dishwasher highlight a luxury yet practical onboard lifestyle.
