The
first
of
the
aluminium-hulled
WindServer
trimarans,
designed
to
transport
up
to
24
people
to
site
at
25
knots,
will
enter
service
in
2013.
Powered
by
a
set
of
four
engines
turning
controllable
pitch
propellers,
the
vessels
will
be
equipped
with
ballasting
systems
–
to
shift
between
rough-weather
mode
and
lightweight
transit
–
and
an
integrated
stabilising-foil
to
beef
up
the
hull
while
cutting
maintenance
costs.
The
vessels
will
have
the
flexibility
to
carry
out
various
tasks
such
as
crew
transfer,
cargo
delivery,
search
and
rescue,
and
diving
operations,
says
their
builder.
