Significant Changes in Yacht construction
Considerable changes in new boat production have taken place over the last 20 years, none more than with Jeanneau boat and yacht production. The most significant changes came between 2005 and 2010 when Prisma moulding was introduced to the Jeanneau product. Add to that the evolution of hull construction and a more cost-effective solution to interior woodwork and the results were that yachts built in the early 2000s bear little resemblance to the craft we see today.
Prisma Moulding (Injection Moulding)
Hull shapes were built in the traditional way using uncomplicated lines. A traditionally laid up deck was constructed in two parts and then glued or even screwed together to form this section of the Yacht. Many surfaces would not have a smooth finish and had to be hand-finished. The old hand-laid deck of a yacht would typically be 30% heavier than its modern counterpart.
The Jeanneau 39i was one of the first production boats to get a Prisma Moulded Deck
Prisma Moulding is excellent for the environment.
I remember going to an American shipbuilders yard back in 2001. As we entered the building, the stench of fibreglass resin was almost overwhelming. The light-hearted advice from the guide was to keep walking until we were out of the workshop! Me being me stood still for a moment realising if I paused too long my shoes would become fixed to the floor! None of the workers used respirators. This excursion was not to a Jeanneau factory; however, all boat builder using a spray to apply fibreglass to resin suffered from vapour problems. Now if you enter a workshop owned by Jeanneau ( Group Beneteau) you cannot even smell fibreglass. The air is clean, and that’s all thanks to injection or Prisma moulding.
Prisma Moulding is stronger
Deck designers were free of traditional angles, and they are no able to experiment with deck shapes that have transformed the way yachts look. Gone are the days when a locker is open to see rough fibreglass. All surfaces are smooth. It’s a fact that a Prisma Moulded deck is lighter and stronger than its conventional counterpart.
Virtually All Yacht Manufacturers now use Glue. Screws are no longer necessary.
Once upon a time, a hull was screwed to the deck of a yacht. Visible screws or bolts along the deck joint and around windows were a selling feature showing the integral strength of the Yacht. As Glue and resin developed Jeanneau realised it was possible to join a hull to a deck with only Glue, however for some time decks were glued and screwed. The only reason for the screws in this interim period being that Jeanneay thought the market was not yet ready to accept an entirely bonded together hull. Sicoflex sealer has now become an essential tool in the shipwrights’ tool kit. Now a Glue called Sicoflex similar to that used by boat manufacturers is used throughout the marine industry.
The end of teak veneer
A real teak veneer was used in production until around 2006. The significant disadvantage to this being the global cost of teak and the difficulty of consistency. Small imperfections in a wood pattern often plagued boat builders. Inconsistency in the quality of wood continued until a man-made wood finish wood became available. From then the grain is manufactured to match. From this point, Yachts became a little less personal; however, on the upside, replacing a door or panel became just a matter of ordering a spare part as they were all the same.
The evolution of a brand
Over 60 years ago it took Henry Jeanneau and a balance of individuals to create a brand. Market conditions fell in favour of this company in the beginning and then experienced judgment (with a little luck) has carried this great brand to where it is today. It’s fair to say it is part of the massive Group Beneteau and had it not been for a take over some years ago the brand might not have survived. The fact is the brand did survive to ups and downs of 60 years regardless of ownership. This survival is a credit to all who work for the company and believe in the Jeanneau brand.
