Since 2023, Saint-Malo-based 3DRefit has been offering an industrial approach to boat interior refits. Far from artisanal interventions, the company has developed know-how in custom design, deconstruction and reconstruction, based on advanced modeling tools. The company's core business is furniture, but it also covers all on-board systems.
Precise modeling and virtual reality
Before any work is carried out, the interior of the boat is dismantled and the empty hull is laser scanned. This provides a point cloud accurate to a tenth of a millimeter, the basis of the boat's digital twin. On this tool, the various layouts are simulated and visualized in immersion using a virtual reality headset. This preliminary stage enables us to validate volumes, traffic flows and technical areas.
Lightweight furniture that can be dismantled and repaired
The furniture designed by 3DRefit is based on sandwich bulkheads made from PET foam, recycled from plastic bottles. This choice reduces the overall weight of the boat: on a 45-foot unit, the saving is up to 1.5 tons compared with conventional plywood. Each module is designed to be brought in as a kit and assembled on board. This facilitates maintenance, since a defective part can be replaced without changing the whole unit.
Respect for the masses and behaviour at sea
Furniture is never installed at random. In-house CAD/CAM software calculates the barycenter of each element to guarantee a weight distribution in line with the ship's original layout. Structural partitions are not modified. This methodology avoids any alteration in seaworthiness, even after a major conversion.
A complete refit, right down to the networks and reservoirs
In addition to furnishings, 3DRefit also works on tanks, electricity, plumbing and on-board electronics. The entire installation can be overhauled, modernized and brought up to standard. The offer is aimed at both second-hand boat owners and new-build yards looking to outsource fitting out.
Circular economy and marine recycling
The components deposited during refits are sorted, referenced and put back on the market via a marine recycling center operated by 3DRefit. This circular approach reduces waste and extends the life of marine components. Ultimately, the aim is to build up a genuine base of reusable materials.
A calibrated business model
The average cost of a complete interior refit by 3DRefit is between 7 and 10,000 euros per linear metre, depending on the technical options. The company, which now employs ten people, is positioned as a technical service provider for more sustainable yachting.
