3. CONTRUCTION
Your
J
109 has benefited both from the care and attention of all the workers in the shipyard
who have been involved in its construction and from architectural and technological innovations,
which place this vessel on the cutting edge of progress. From its wealth of experience, J EUROPE
has selected only high quality products for the construction of your
J
109.
The hull and the deck are in sandwich using unified, bidirectional materials. They have been
manufactured by infusion using the TPI patented “SCRIMP” process, which enables a laminate to
be produced with a glass content in excess of 65% in the structural components.
The interior fittings in your
J
109 are made from polyester and marine plywood and are
laminated to the hull and the deck for greater homogeneity and rigidity. We pay particular care and
attention to the quality of the varnish, which is applied in several coats.
The floors are in grooved laminated plywood.
The ballast is glued with epoxy adhesive and solidly bolted to the hull with stainless steel
backing plates and nuts. It is fitted at the end of construction, once the hull has become sufficiently
rigid to avoid any risk of deformation. The lead ballast is protected with an epoxy coating.
Your
J 109’s Bowsprit is made from carbon. A U-shaped chain plate wire enables you to
lash the tacking control end block for the asymmetric spinnaker. Inside, an end enables the jib
boom to extend from the rear of the cockpit. Warning: do not operate the jib boom when there is
someone in the front cabin.
The rudder is suspended on self aligning bearings and made from glass laminate on an
aluminium rudder stock .
