Spazzo is a modern International 8-Metre yacht built
to the design of
Dipl. Ing. Juliane Hempel. The hull is the result of
extensive tank testing at
the University of Kiel, Germany. The yacht is uncompromisingly
built to the
highest standards using the best material available.
The yard of Josef Martin
is well known for their first class and impeccable quality
of workmanship
following generations of yacht building on the shores
of Lake Constance.
Spazzo has been constructed according to the 1993
International Eight
Metre Class Rating Rules in cold moulded mahogany. The
construction
followed the Lloyd's Register Rules for the construction
of wooden yachts
1957 and the building survey and classification has
been performed by
Germanische Lloyd from Hamburg. (Reg. No. 92728)
Hull construction
Vacuum cold moulded construction using West System
Epoxy resins.
7 Layers of diagonal mahogany, the last layer in carvel.
The hull thickness
depends on the position, on average 26,5mm. Underwater
the hull has been
additionally reinforced with 2 layers of biaxial glass
and epoxy. The hull has
been vacuum pressed. The keel is built from laminated
mahogany and extra
reinforced at the keel bolt area. Two strong laminated
ring frames have been
placed in the mast area. The shelf is built from light
weight and defect free
spruce. The bulkheads have been constructed from water
boil proof plywood
AW100. The load bearing bulkheads are 18mm, the light
bulkheads are 10
and 12 mm.
Deck construction
The deck construction is a high tech foam laminate.
The deck construction
was vacuum laminated in a composite of:
1- Underdeck 4mm 3-layer plywood
2- 18mm Herex 80 hardfoam
3- Top deck 4mm, 3-layer plywood
4- Teak deck, 6mm bent strips
The deck beams are of light and defect free spruce,
clear varnished. The
bottom of the deck has been varnished high gloss white.
The teak deck is
finished with mahogany linings. The cockpit and stern
are also in clean
varnished mahogany.
Cockpit
The cockpit is not self draining and constructed
in a light weight foam
composite. Teak veneer walking floors combined elegance
with excellent
anti slip properties.
Coachroof
The coachroof is built from selected quarter sawn
mahogany. Laminated
construction ensures strength and minimum weight. The
accommodation is
to the minimum requirements, two fixed berths midships;
in addition a light
weight pipe berth is installed in the fore castle.
Keel and ballast
The keel is cast from antimon hardened lead. The
keelbolts are in stainless
steel 316. The trim flap is also cast in lead. The
wings are laminated and
ballast neutral.
Rudder
Narrow and deep rudder following the latest developments.
Constructed in
glass fibre with reinforcements in AIMg Si1. The rudder
has a core of Airex
C70/90 hard foam. The rudderpost is made of glass fibre
and has a
Speedwave pendule bearing system.
Mast and rigging
Tapered aluminium mast made by Speedwave from a
Proctor extrusion.
Boom made by Speedwave, also from proctor extrusion.
Double spreader
arrangement with jumpers. Speedwave rod rigging. Speedwave
hydraulic
system for adjustment of boomvang, mainsail outhaul,
mastfoot and fore
stay. Carbon fibre spinnaker pole, oval and tapered
section.
