There’s a lot more to the modern chined hull’s used by Jeanneau than may be obvious, whether designed by Philippe Briand, Marc Lombard or Daniel Andrieu. This hull design is combined with other factors like the position of the mast and keel to provide an overall package that is balanced and forgiving. Chined hulls extend the waterline beam so that when the yacht heels it effectively heels at a wider point from the centreline, so effectively adds stiffness. The chine itself offers an increase in buoyancy at the point of heel when it becomes immersed, so it takes considerably more power to heel the yacht further, but the line of the chine at the same time makes the yacht want to sail in a straight line. So where a yacht normally loads up the rudder when it becomes well heeled and tries to round up, a well-designed chined hull does exactly the opposite. The benefit is a yacht that is incredibly forgiving and will allow you to get away with being hit by a strong gust of wind, or becoming overpowered without having to reduce sail in a hurry. The advantages when cruising short-handed, or sailing with an inexperienced crew are enormous.
This is where Jeanneau’s optional Code 0 sails come in, because they work in perfect harmony with the chined hull offering easily handled performance from close hauled to broad reaching. A client recently reported boat speeds well into double digits broad reaching with the code 0 on his Sun Odyssey 439 on a delivery to Queensland. He described it as being effortless compared to his previous yacht of the same size.
If you’re in themarket to buy a new yacht you owe it to yourselves to contact your local Jeanneau dealer and ask for a test-sail on one of the new hulls. The existing range of chined hulls covers from 32 to 50 feet.
