Boat building  
Building a launch calls for a wide range of skills in handling different materials such as wood, composites,
metals, etc.
 

Design (CAD)

The drawing office has a high performance CAD system.

This is used to design and visualise the hulls, superstructures, accommodation and the many different types of fitting needed to build a launch.

This system makes it possible for customers to view three dimensional images of the various options available.

For some projects, we work in close collaboration with outside designers.
 
 

The woodworking shop

The woodworking shop is a historically important part of the shipyard as wood was for a long time the only material used for boat building.

The woodworking shop now produces the moulds for the hulls and superstructures. This work demands high precision as the quality of the mould is critical for the shape, performance and the appearance of the polyester structures.

The carpenters are also responsible for making the launch fixtures. The attention paid to finishing is one of the shipyard’s hallmarks and the launches have a very high quality finish.

The woodworking shop has a comprehensive set of wood-working
machinery :

- planes,

- bandsaws,

- jointers,

- spindle moulders, etc.

   
   
 

The composites shop

The composites shop is an insulated, heated workshop for moulding the hulls. The decks, bulkheads and superstructures are also moulded here before they are assembled.
The moulding workshop has a programmable, regulated vacuum system, a glass cloth impregnation system and an overhead travelling crane. Before moulding a hull, the mould must be prepared by polishing and waxing. The gelcoat is then applied to the mould and the glass cloth impregnated with polyester resin is layed up in the mould.
The hull will later be reinforced by a laminated polyurethane foam structure. The whole process follows drawings approved by a naval architect.
 
 
The mechanical engineering shop.
This is the most recent building, built in 2002, next to the extensive finishing shop. It is functional and well equipped (lathe, band saw, plasma cutting, welding stations, etc.). There are several specialised trades involved. The sheet metal workers produce the wide variety of metal parts required for launches, such as guard rails, bow and stern rails and ladders as well as tanks, hinges, etc. These metal parts are usually one-offs, in stainless steel or aluminium, and are made in the workshop and adjusted to fit on board. Fitters are responsible for fitting the engines that must be mounted, aligned accurately and connected to the supplies and exhaust. Each engine requires a large number of accessories and individually formed pipes. Fitters are also responsible for mounting the rudders, trim tabs, etc
   
   
 

Finishing
The finishing and fitting phases take place in the boat yard’s large workshop. This has slipways giving direct access to the sea.

The cradles are on rails and are winched for launching boats and hauling them back up. The handling equipment also includes overhead travelling cranes.

Everything is checked to ensure that it meets the owner’s requirements and the finishing touches are made.
 
 

Tests and approval ---> look at our video
The tests are carried out in the presence of the owner and include all those involved: the shipyard, of course, as well as the safety certification body and the various designers. The launch and all its equipment must be tested to ensure that it conforms to the specifications in terms of seaworthiness, performance, comfort and efficiency. After testing, the launch is handed over to the customer, with all necessary certification.
