The ideology of the 'jonques de plaisance'

Dimitri Le Forestier (IFAN) has designed these boats with one overriding priority: that they should respect as much as possible the aesthetics of classic junks, whilst at the same time, take advantage of modern construction methods. Hence the construction uses glued laminated timber (also referred to as strip planking). There are two main reasons for this choice: Firstly, the construction can easily be undertaken by non-professionals and secondly, the weight of the boat is greatly reduced. The glued laminated timber method results in a boat which can be built without a mould, is lighter, has a moderate displacement and is stronger.

Of course, the wood factor plays an important role in the seduction. What could be more pleasing than to walk on a teak deck, letting your hand run on a timber handrail and below deck, having your personal space fitted in timber with everything just where you would want them to be, that's important. And to sleep in a real bed, what comfort!

Chantier Ultramarine Infos

Dimitri has sailed around the world for 12 years and has designed sailboats most his life: Cutters, sloops, schooners and others. It is towards the end of the '70s that he revisited "the junks", on board of which he had sailed during his stays in the East. Impressed by the Chinese junks' performance, their stability, maneuvrability and economy; he reinvented them beginning with the 12.5m JDP. Dimitri offers very detailed plans accompanied by a construction guide (currently being translated into English) which pay particular attention to the needs of the amateur builder.

Over time, Dimitri has written numerous articles for Loisirs Nautiques and he is acknowledged in France as having redefined sea-going junks. He has some fifty Jonques de Plaisance to his credit and continues to design the boats he loves.

Why a junk?

The choice did not come about by chance: having extensively sailed the East, Dimitri Le Forestier was in a position to appreciate first hand the marine qualities of these boats. Used for commerce, the traditional junks were required to make good speed, to negotiate entry into ports which weren't always easily accessible and often windward. Junks also must brave typhoons (unfortunately rather common in the China Sea).

The junk's typical rigging has proved itself exceptional in its use: the deck hardware is most economical and above all, easy to handle: the flexible masts are not shored up (think of the savings thus achieved). The benefit is the incredible ease of circulation on the catwalk since there is nothing to impede traffic!

Construction by professionals or amateurs builders

We have pleasure in recommending Ultramarine Boatbuilders shipyard for the construction of our jonques de plaisance in India. Located in Pondicherry, on the East coast of India, this French shipyard offers its clients several options: beginning with carpentry kits through to the finished boat 'helm in hand'.

The savings that can be achieved are a substantial advantage, as is the professional guarantee on the work done and on the quality of the timbers used.

THE KITS: Hull Carpentry and Deck & Roof Carpentry focus particularly on the needs of amateur builders and ensures them a solid start in their venture.
