The origin
The TOUCHWATER is designed as a
wave piercing semi-planing sailing catamaran, not following class
or regatta restrictions. In its origin version an 18 ft sport
catamaran, compared to formula 18, reduced weight offers advantage
in speed and handling. But nevertheless the weight is sufficient
for quite stable sailing in unsteady winds.
Aerodynamics
The 20 m² sail area, versus 18HT formula,
is split to main sail and jib. The moderately stretched rig provides
good rolling stability especially for lightweight crews, in stronger
winds and incoming gusts.
For further improved rolling stability also a smaller main sail
with slim head may be rigged.
Shrouds are fixed to the mast the way the
wind load aligns the mast profile to the mainsail profile for
optimum aerodynamics. The mainsail is boomless and manual adjustment
of mast rotation isn't necessary.
Pure sailing
Easy handling is the most relaxing and
also safe way to enjoy the time on water. Therefore operating
devices controlling the boat are reduced to a minimum and conveniently
arranged.
Smart technics for easy performance
Technical details
For constructing the TOUCHWATER,
it was important to allow for quick and reliable checks of all
components. For easy replacement, standardized fastening elements
are used. Shrouds and stays are fitted with the thimble / stamping
sleeve system, which is also used in aviation and easily enables
state control of the wire pressings.
The mast is sealed and the halyards are
led outside the mast. Water can't enter in case of capsizing.
The slim mast lifting body prevents a turn turtle and helps righting
the boat again.
The mast fitting is not clinched but bolted
through the mast. Weakening of the mast by rows of rivets is
avoided. Fatigue of rivet joints can't happen and the rig remains
reliable long-term.
The boat is equipped with four bionic shaped
aluminium fins. Form and installation at the hull chines reduce
the lateral drift efficiently and, compared with daggerboards,
the fins are much more robust in case of ground touching.
Individual design
Is there a perfect boat?
Just one for all purpose probably not. But the one fitting best
personal demands might be nearby. Even more the one being designed
according to individual ideas.
The EU directive on recreational craft
and the applicable harmonised standards allow for various construction.
Due to the flexible manufacturing process it is very easy to
use this range for the TOUCHWATER hulls e.g. to match
individual hydrodynamic characteristics or design.
For instance the hull width can be adapted
very easily for a special crew weight, e.g. for single-hand sailing.
Also the balanced semi-planing characteristics may be changed
to meet individual ideas or to fit the boat to special wave conditions
in a preferred sailing area.
Or the hull nose is shaped individually
- and of course there are a lot of alternatives for colour design
