SAILLBOATS

     To finish for once and for ail with sailboats whose technology dates thousands of years, we have developed the sailboat with a variable profile. No more shrouds, no more ropes or pulleys or halyards, only a rigid sail with a variable incidence and surface area which gives the traction necessary for the operation of this sailboat. Whatever the size of the sail, one person alone or even the automatic pilot coupled with the computer on-board would suffice to find the optimum position of the sail in accordance with the speed of the wind, the relative wind, the course, etc.

Extremely simple and reliable with feathering possible, the productivity of this sail is greatly superior to that of ail existing sailboats and has the advantage of having a smaller trail.

Thus the sails area necessary for a desired traction is much less than for a Kevlar sailboat, for example, and allows the centre of gravity to be lowered and speeds as yet unreached to be achieved, speed of more than 40kts. With this new design, it is no longer necessary to manoeuvre the sails on deck. No effort is required and there is no danger when the sea is rough; everything is controlled from inside the cockpit or by remote control if one wishes to navigate whilst sunbathing on deck. Entirely watertight and unsinkable, this sailboat uses other technological developments to such an extent that the latest racing catamarans or trimarans are rendered obsolete. This project is reserved for those who wish to win ail the water races or for those who intelligently wish to take advantage of the technological advances in safety and performance.


SOLAR-POWERED TRANSPORT BOATS

Silent and economical, non-pollutant and reliable, such are the principal characteristics of this new means of navigation which combines sun and water in an entirely innovative design. There will be a saving on fuel and also on the practically non-existent maintenance required because of its all-electric design. It cruising speed which is higher than l2Kts and its freight capacity makes it possible to transport heavy loads by sea or river.


RAPID SOLAR-PQWERED BOAT

This fast electric boat designed following the same principles as its older brother (solar-powered transport boat) benefits from optimized aerodynamics which protect the boat from gusts and obtains an excellent hydro and aerodynamic drag factor. With two electric engines, this catamaran is very stable and can reach a maximum speed of more than 20 Kts. This is possible because of the ultra-light weight of this vessel and through the use of pre-impregnated compound materials. To travel in this infinitely autonomous and free (in the daytime) boat which is 100% non-pollutant and silent, would be an irresistible and unprecedented experience for any sailor.


SPEED BOATS

With the new generation of ultra-rapid speed boats on hydrofoil, high speed navigation on rough seas is fast becoming possible. No more rolling or incessant reeling which make a crossing on a rough sea rather trying! As well as excellent stability, these hydrofoils present only a slight resistance to the boat's progress and allow high maximum speeds (more than 7OKts) for a smaller amount of fuel consumption when compared to a classic cruise boat. The combination of aluminium and compounds guarantees an extreme solidity and incomparable lightness for a vessel in this category (more than 30 meters) powered by more than 10 000 cv. With watertight fly and cockpit, the conditions for pleasant navigation are perfect, and it is extremely safe in ah weather conditions.


RECORD BOATS

Monohull record boats, constructed in the image of off-shore boats, are different from these latter because of the technological innovations used combining air and water. Submerged and aerial areas control the piloting and the stability of this machine. As regards the propulsion system, which is adapted for high-powered machines and is self-stabilised, it no longer necessitates momentary piloting of the speed.

The bladed turbine at variable incidences is responsible also for controlling the propulsion productivity necessary at every second of navigation. The aviation-style cockpit which is closed and reinforced is but one of the efforts made to maximise the safety of this boat. Maximum speed is higher than l00 Kts.

SUBMARINE VESSEL AND DIVING BOAT

For those for whom speed is not a dominating factor, but who wish to have an exceptional vessel, we offer this submarine for extremely tranquil navigation. In fact, in very rough weather and regardless of the vessel, the navigation conditions can become unbearable and cause sea-sickness even to the most experienced sailors. With its submarine qualities, this vessel is sheltered from the swirls, eddies and waves of the surface by being more than 30m under water.

Thus, in being sheltered from the rough sea and using electric motors run on hybrid metal batteries, one can enjoy a period of calm and appreciate the beauty of the deep sea. One can then rise to the surface after having checked with periscopic submersion that the storm is over. More than 60m long and equipped with quadruple motors, this diving boat combines strength, stability and originality and cannot but delight its owner. The titanium and compound materials used in its construction make it particularly light, which saves on fuel and permits a maximum surface speed higher than 3OKts.
