The Jonque de Plaisance® designspreserves the aesthetics of classicChinese junks, whilst at the sametime maximising the advantages of modern construction methods.

Conceived specifically with theamateur builder’s in mind, the plansare explicit and are accompaniedby a detailed construction guide(currently being translated in English).

The JDPs are characterised by thesimplicity of their construction, theirstability and performance at sea,their easy maneuvrability andspacious living quarters.

Jonque de Plaisance®

WHY A JUNK?The birth of the Jonques de Plaisance is the product of a simple concept: to

design and build a boat which is modern at heart but which respects the

aesthetics and principal characteristics of traditional sailing junks.

Having sailed the East extensively, Dimitri was able to appreciate the marine

qualities of these boats first hand. Used for trade, junks were required to make

good speed, often had to sail into the wind to reach ports with more or less

easy access. Junks also needed to be able to survive typhoons – a common

occurrence in the Chinese Sea.

The junk's typical rig proves itself exceptional in its use, its economy and

above all, in its low stress operation: the masts are unstayed, thus some

further savings are achieved. Another benefit is the incredible ease of

circulation on the deck, since there is nothing to impede traffic!

THE MODELSOver fifty Jonque de Plaisance® have been built and sail worldwide, and

there are five designs to chose from: 9m, 10.5m, 12.5m, 14m and 16.5m. With

the exception of the Jonquinette 9m (developed in collaboration with

architect Jean-Pierre Villenave and built in marine ply), they have all been

granted Category A (CE) classification in France (worldwide navigation).

Smaller models are also available such as the 3m and 4.7m Jonquinettes.

BUILDING A JUNKThe HERRESHOFF construction method is well known and has been

recommended since the end of last century (or the other). It is used by

numerous architects, with only simple subsequent modifications which were

made possible by improvements in the quality of epoxy glues available

according to the size and purpose of the boats.

The method: Glued laminated timber (strip planking), is well within reach of

the amateur builder. It does not require a mould and results in a boat which

is lighter in weight and stronger than the traditional timber building method.

It is a known fact that building and maintenance costs are directly related to

the boat's weight.

The timbers used are readily available (iroko, mohagany, oregon, nordic pine,

teak, etc.). The reduction in weight means that, for the same waterline

length, a hull thus built will have a considerably reduced displacement.

Specialised epoxy glues also give unequalled durability to laminated timber.

As a result, maintenance costs are substantially reduced.

The masts are also assembled with glued laminated timber and have a hollow

centre. Their assembly is deceptively easy, as with the rest, by one person alone.

The sails are made of dacron: 270-300g per square metre – this would be

insufficient for a conventional sailing boat, but when reinforced with

bamboo, this is most adequate.
