Having our own team of engineers in house, while most builders outsource all their technical work, allowed us to develop our Research & Development office. Thus, we keep on implementing new technologies, new equipment and new materials on our prototypes today that will end-up on your boat tomorrow. The technologies we use are various, and here are a few examples of what stand behind the scene of our construction processes.
While most our hulls are tank tested, each boat we build, once the weight distribution plan has been completed, is checked using our CFD software. This helps us making sure the balance of the boat is not affected by the various options chosen by the client. At Canados, we are very attentive to performances as we always consider a boat should offer the best possible liter to nautical miles ratio. With deep CFD analysis, we are able to define the needed kW at any given speed and extrapolate the consumption.
Most of our hulls offer superior performances and astonishing seagoing capabilities, and there is no secret as of why. Not only our naval architects are incredibly experienced, we also considerably invest in tank testing. The hull forms of the Oceanic 140’ have been extensively tested to reach the level of performance and balance we were willing to achieve. As a result, we pride ourself to have invented a truly new hull design that combines, for the first time, a twin stepped bottom, with keel and bulbous bow that will be capable of navigating with extraordinary results at any speeds between 8 and 27 knots.
Yachts dimensions are getting bigger and bigger but lots of owners are still willing to be able to anchor close to the beach. Thus, we are now offering the possibility to produce some of our hulls with tunnels. To give a concrete example, on the Oceanic 140’ model, this configuration allowed reducing the draft over 50 cm. At 44 meters, the Oceanic has only 2,10 meters under water and for the owners using their boat in the Caribbean, Florida or Bahamas, it truly opens new destinations.
COMPOSITES AND SURFACES
At Canados, the time when composites meant fiberglass and polyester resin is long gone. In almost every single of our models, we are using E-Glass, Kevlar, carbon fiber in all sorts of rowing configuration from mono-axial to quadri-axial. Coring is made of stabilized honey comb closed cell foam that not only increase buoyancy it also absorbs vibrations and parasite noises. Most composites parts exposed to the sun are post cured at 70° Celsius to make sure no cracks or bubble will appear in the future. As well, all our hulls are faired and painted in Awlgrip which offers much better aging than gelcoat used by most builders.
VACCUM BAGGING AND INFUSION
Using the best building materials is not enough. All the Gladiator hulls and deck are laminated using Vacuum bagging or infusion. This process helps making sure the resin is perfectly distributed all over the impregnated surfaces. This tremendously helps reducing the lamination weight. Hand lamination is still used in some areas and for certain parts, but infusion ensures that each square meter of polymerized lamination weight the exact same.
ULTRA-SOUND TESTING – QUALITY CONTROL
Composites hulls are not only multiple times stronger than steel or aluminum; they also offer stunning impact resistance. No wonder why bullet proof vests are made of Kevlar and not from metal… The truth is, welding steel plates is a fairly simple process that doesn’t call for any specific technologies, but composite lamination and polymerization is a science. As such, the finished products have to be tested using modern technologies such as ultra-sound screening. Each hull we produce is meticulously checked to ensure the lamination and bounding of the core are perfect.
Mostly used fitted on some models the Gladiator range, Surface Drives are a technology we are very familiar with. We mainly use JDM Special Surface Drives that not only offer considerable gains in performances and handling, the Special version also provides unseen before reliability and solidity. This specific transmission system, unlike straight shafts, is equipped with power-trim. The inclination changes of the all-stainless-steel transmission allows to be on plane, with a boat running perfectly flat from about 15 to 17 knots, depending on the boat. Not only if offers much larger use ranges, it is also totally reliable as it has no hydraulic hoses are in the water.
5 AXIS MILLING MACHINE
The perfection of our interiors is the result of the mastery of our carpenters and craftsmen who are trained for years before being given the responsibility of heading an interior project from inception to delivery. As much as man’s hands are the irreplaceable when talking about carving or doing marquetery, the association of this secular know-how with the latest high tech 5 Axis milling machine is your insurance the pieces of furniture onboard you boat will not only be unique, they will be perfect. The higher onboard or the more to fore the piece of furniture is located defines its manufacturing process as it is very important to spare weight in critical places such as the bow or the upper deck to increase performances, handling and stability. Therefore, it happens often that we use Nomex for the inner structure of a piece of furniture which results in a gain of weight that can vary from 40 to 60%.
The performances of a fast boat are the result of very complex equations that are based on a number of factors. The most commonly known being the hull shapes, transmissions, propellers, weight and naturally engine power. But there are other parameters too often neglected by boat builders: engine combustion. All engines are pumping fuel from the tanks, burning a part of it, and unnecessary fuel is being returned to the tank after passing by the fuel pump. As a result, the fuel overflowed to the tank(s) gets warmer and warmer. It is no secret that an engine delivers more power and better combustion when the fuel is cold than when it is warmer. On some of our high-performance models, we install a fuel intercooler between the fuel pumps overflow valve and the tank to make sure that during long period of use, the fuel left in the tank doesn’t go up in temperature.
