We present four of our yacht design and building projects:
a wooden construction of an America Cup boat replica,
a steel construction of a motorsailer yacht,
a wooden construction of a Greek traditional boat and
a composite construction of a luxury motor yacht.
|
The America's Cup 21m wooden classic racer yacht is a replica of Defiance, designed by George Owen for the 1914 race.
Defiance "was beautifully sailed and used exceptionally good judgment, surprising everyone by the slippery way in which she
worked out to windward". She was double planked on steel frames and gaff rigged with club topsail and self-tacking jib.
The replica is wooden having 25 tons total displacement, 9 tons of which are the lead ballast keel.
The boat follows the Lloyds rules for wooden boat construction.

The 32m steel motorsailer yacht is a modern hull with the appearance of an American schooner.
The boat has three masts (the tallest is 35m) and she is driven by two 250hp engines.
The boat is designed to be classified as an Offshore Racing Yacht
according to the American Bureau of Shipping (ABS) rules.
The displacement of the boat is 110 tons which 40 tons is
the weight of the steel hull and 40 is the weight of the lead ballast.
All ballast is placed inside the deep keel.
The deck is wooden and the bulwark is wooden planks over steel frames.

The 16m traditional wooden sailing boat is of the Perama type, a cargo carrier for the Greek islands.
It is designed as a gaff rigged sailer with two masts.
For the construction of the boat the loft floor technique was used.
The frames were made double sawn and the planking was made carvel-single plank.
The shell was made watertight by caulking.
The deck houses were made of solid timber with bronze windows.
The deck was planked by narrow planks with rubber sealant.
Parts of the boat were left in natural wood in order to preserve the style of the local yard.

The composite 49m luxury motor yacht was built originally as a torpedo boat for the German navy in the beginning of the sixties.
The boat was later transformed into a motor yacht.
We extended the stern of the boat by three meters in a form of modern double stairs arrangement.
We also built new parts of the aluminum superstructure.
The original construction had steel floors, steel bottom longitudinals, aluminum frames, aluminum deck longitudinals
and three layers of wooden planking.
The first and the last layer were made of mahogany and run longitudinally while the intermediate layer
was made of teak and runs diagonally.
We designed the extension in order to be compatible to the initial construction, light and strong.
The hydrodynamics of the underwater part of the extension were studied in order to prevent turbulence formation and added resistance.
Finally the aesthetic of the original form had to be preserved.
After taking away the old wooden transom we extended the bottom steel longitudinals backwards and up in a closed form
connected to the aluminum deck longitudinals with bimetallic elements.
The new frames were welded to the structure and the three layers wooden planking was extended and bolted to the frames.
An adequate overlapping to the old planking was made for strengthening purposes.
The project was under the approval of the Bureau Veritas.
