Client:
‘Carbon’,
the
Dibley 250
is a purpose built racer designed primarily for twilight
and rum racing. An added requirement was that it had to be
suitable for the
Coastal Classic
in both design and construction. It features a hull design
that is fine on the waterline and has aggressive flare in
the hull to create cockpit wings. The entry is fine forward
with a little hollow and slightly tapers in at the stern to
create a balanced hull form when heeled. The keel has the
obligatory bulb with a healthy 380 kg for stability when
powered up and short-handed. An added bonus is the extra
stability while at her mooring and in pre-start maneuvers.
The cockpit is high and wide with rounded edges for greater
comfort. In contrast the coach roof barely exists and
basically provides a platform for fittings and the rig.
The initial commission for the
Dibley 250
was from a Northland couple that briefly raced her from
their local club. Another owner said he had been looking at
other yachts and found exactly what he was after with
the
Carbon.
He commented,
"We hit 19 knots on the trial sail and that basically
was all I needed to make a decision".
The delivery to her new home in Westhaven was accomplished
with a 15 hp outboard during the windless winter and
Carbon
has already turned heads in her initial races.
Carbon's
name is no accident. Hull, rig, rudder and the retractable
bowsprit are all carbon fibre. In addition the interior is
au natural with the inside laminate clear finished to show
the black laminate. However in reality there is no
interior! A fitted bucket and camping stove are installed
for safety purposes and there is adequate room for sails
and other equipment. The hull and decks are a carbon foam
laminate and bulkheads are plywood reinforced with
unidirectional carbon. All deck gear is Harken with the
only winches two single speed 8s on the cabin top. Jib
trimming is 2:1 with a coarse and fine tune. The mainsheet
runs through a Harken double cleat to allow coarse and fine
trim without a separate fine tune. Due to the low boom a
vertical boom vang on a circular track was fitted. This
allows easy access to the hatch and is a lot easier on the
crew. An added benefit is the bridge deck, which will
reduce the likelihood of water getting below in the event
of a serious knockdown.
The carbon mast section is an elliptical shape designed
by
Chris Mitchell
and has been proven on a number of other high performance
yachts. Swept back spreaders are carried out to the
gunwale. Topmast backstays are not required and removable
fractional backstays are only fitted for use in coastal
races. The 2-metre prod is housed in the hull and extends 2
metres from the bow.
