Design of the houseboat: a self-sufficient solar catamaran

Since 2022, our naval architecture firm SB Yacht Design has been working with the shipyard Ibaïa Boats on the Bassin d’Arcachon to develop an eco-designed Houseboat catamaran. From the design of the hulls and superstructure to the interior layout, we have conducted all the studies. After a year of work, it is finally in the water.

The features of the Houseboat.

Combining the comfort of an apartment with a 100% self-sufficient boat: this is the challenge we embraced with the creation of the Houseboat. This boat, with a length of 16.25m and a width of 4.40m, offers an interior space of 50m² and exterior spaces of 30m². It was designed for navigation on rivers and streams. The integration of solar panels ensures not only its navigation but also its domestic use.

A custom interior layout.

Our role as naval architects is to optimize your living space to combine comfort, aesthetics, and functionality. Our challenge with the Houseboat was to optimize 50m² of living space to accommodate 6 people. The Houseboat offers the comfort of 2 bedrooms: one is 11m², and the second bedroom is 8m², adjacent to a bathroom. The boat is equipped with a spacious bathroom with all necessary amenities. The 17m² living area features an open kitchen and a convertible sofa to accommodate more guests. This room is the heart of the boat, the living space, so we integrated a stove to make it comfortable year-round.

Our eco-design approach.

The choice of materials.

We have incorporated recycled, recyclable, and bio-sourced materials. This allows us to have a boat that is less polluting during manufacturing and is largely recyclable at the end of its life.

A solar-powered autonomous boat


To achieve 100% solar autonomy for the boat, it was necessary first to calculate domestic energy consumption in order to optimize the boat’s energy efficiency.

Next, we integrated solar propulsion systems using 22 solar panels. The energy generated by the sun is then stored in batteries, which power the boat for navigation and interior equipment.
