building 100% aluminum sailboats

Skilled workforce at Alubat

Alubat is a renowned French sailboat builder that builds high-quality 100% aluminum sailboats. With more than 50 years of experience, Alubat has established a strong reputation for building durable, reliable, and seaworthy aluminum sailboats for long-distance expedition sailing.

WHY 100% aluminum sailboats

Experienced sailors stand by its resistance. During an impact, the hull will deform but will not rip, meaning your boat stays watertight. 

With a density and mechanical properties of both rigidity and shock absorption, aluminum is undoubtedly the ideal material for building yachts that are both light and safe. In addition to the flexibility it provides in terms of building processes, aluminum is a suitable material for building custom yachts.

The quality of hull construction, the durability of the woodwork and the expert electrical installation guarantee the resale value of your yacht.

Unlike fiberglass, aluminum is recyclable.

Aluminum welding

Building Aluminum Sailboats | Your boat takes shape in the skilled hands of metalworkers.

Louison - Metal Worker/Welder

In their own words

“It’s always quite surprising to see how the beginnings of your boat actually happens. First, the pre-cut aluminum plates arrive on a pallet. From this initial flat shape, our teams create curves and form around the framework structure. The know-how of our team lies in the assembly and spot welding.

We assemble the hull upside down, with the ballasted daggerboard installed about 3 weeks after the beginning of construction.

We’re in constant communication with the design office team, as certain options have a direct impact on the metalwork process.

It takes an average of 10 weeks in the metal shop before the boat reaches the painting stage.”

Your boat spends 4 full weeks in the paint booth, receiving a total of 9 coats of paint, before moving on to the assembly workshop.

First, the inside of the boat is thoroughly dusted and vacuumed.Then it is cleaned with hot (120°) high pressure water for de-greasing.

Some areas, such as the hull, chainplates and cleats, are masked before the application phase of the painting cycle begins.

A first coat of epoxy primer is then applied on the deck, hull and interior up to waterline level.

All the welding points, such as handrails, stanchion feet etc. are coated and sanded to apply a second layer of epoxy primer. Then the finishing primer is applied and sanded again for a smooth finish.

Finally the application of 2 coats of polyurethane lacquer completes the painting procedure.

For the non-slip areas, masking tape is applied, then the paint is passed over with a lacquer roller followed by a sprinkling of microbeads. This is left to dry for 24 hours before applying a matting agent.


Craftsmen install the custom-made furniture in a designated carpentry workshop.

In their own words

“With 3D modeling and CNC machines, our carpenters are able to meet any request for customized fittings, whether for new builds or renovation work. 

We apply polyurethane foam insulation under ceilings and on the topsides up to the waterline before any of the furniture or flooring is installed. Thermal bridges create effective control of condensation.

For specific navigation in cold climates, we recommend additional insulation in sprayed cork.
