Garage Door

Monaco 2013

Finding an accessible storage place for the fenders was the main issue on this 58 foot motor yacht.ensemble

The idea of opening an access into the garage door was evident, but made difficult due to the reinforcements  and  stringers  located  in  the existing door.IMG_1791

The decision was taken to build a completely new garage door including a small, easy to open, aperture.IMG_1787

The use of composite under infusion process, allowed us to reduce the door weight by 50 % compared to the old one, thus increasing the storage capacity.DSCN3486

Removable Gangway

Alpes-Maritimes 2012

Approaching the coast with a tender and landing people was the request of the client.

If building a passerelle is simple, installing a removable passerelle on the rocks was a real challenge.DSCN1559

Drilling holes on the stone made it possible to install discrete bolts where the passerelle can be attached in 30 seconds by one person.Image1

Carbon Gangway

Saint-Jean-Cap-Ferrat 2012

On this wonderful Olin Stephens design from 1937 the wooden passerelle needed to be light but strong.athena passerelle

Being on a wooden boat, the finish needed to be “varnished wood”.


The  solution  of  a  carbon/infusion  process construction was chosen for weight consideration. The finish is perfect “wood like” paint. (being close to the real teak bulwark capping rail would not allow an approximate result)

The pleasure of handling a light passerelle is now compatible with the respect of the wooden style of sailing yachts.


Jacuzzi Conception

Monaco 2011

The request of the client was simple : make a Jacuzzi on his boat that could be used in 20 min, the time for him to reach Monaco from Nice airport.dear henricoussin1

The boat had not previously been designed with a Jacuzzi on deck so several issues were to be solved:

  • would the stability of the boat permit the addition of 700L of water on deck?
  • would the structure of the deck sustain it?
  • would the electric installation on board be powerful enough to heat 700 L of water at 34°Celcius in 20 min time?OLYMPUS DIGITAL CAMERA

A study of the metacentric height showed that the foredeck was a place low enough to locate 700 Kg with no significant influence to the stability.

An extra beam underneath the Jacuzzi would distribute the extra weight to the existing structures of the hull.OLYMPUS DIGITAL CAMERA

The addition of water heaters in the front area allowed us to have enough “ready to use” hot water at our disposal to quickly prepare 700 L of warm water.OLYMPUS DIGITAL CAMERAOLYMPUS DIGITAL CAMERA

New teak surrounding surfaces and access steps contributed to give a new life to the foredeck area of this 33 M motor yacht.

TV Lifts

Viareggio 2008

The request of the client was to install TV suspended from the ceiling on the main and upper deck. The time given to us to complete our intervention on board was only three weeks.main deck port side

While several good lift and fold systems exist on the market, none of them would fit in the very thin volume left in each ceiling.

A studied and specially created mechanical system based on gas and electric rams driving a composite frame made it possible to fit the screens on their dedicated place.main deck ouvert

With all the systems tried and tested in the workshop, the remaining work on board within the limited time was to cut the ceiling and finish off with a small gel coat cornice.

Our skill and experience allowed us to find solution where an existing device would not satisfy.

Fly Bridge Hard Top

Saint-Jean-Cap-Ferrat 2013, 

On this 23 M motor yacht, the old bimini made of stainless steel tubes and canvas suffered each year from the sun and rain.

It was too weak to be left out with big winds and was not giving much protection from the summer heat. It was thus decided to replace it with a hart-top situated in front of the existing roll bar.



This permanent part needed to be strong enough to sustain all bad weather conditions the boat might encounter while remaining light enough to avoid needing extra reinforcement and weight in the upper area.



The careful design of the new shape and its air flow simulation enabled us to keep the windage low even when facing an eighty Knots apparent wind.


A light composite construction allowed us to keep the weight to a minimum. The addition of three apertures equipped with smart glasses made it possible to look at the stars at night while enjoying the shade during the hot sunny days.
