Sailing Performance
Scruffie’s designer, Derek Ellard, is an ex-East Coast sailor,
who grew up tackling the strong tidal streams and uncertain breezes
of the English coast. If you need to short tack up a river to get to
your
mooring before the light goes, you realise that sailing performance
isn’t
only about winning races. Derek still loves sailing, and refuses to
design a boat that doesn’t sail well. All the Scruffie boats
will at least keep up with other similar sized boats, and some (especially
Secret)
will get to that mooring with time to boil the kettle, settle down
in the cockpit and watch the rest catch up in the dying breeze.
Structural
Strength
The materials and method of building result in a very tough, rigid
and durable hull. The engineering of the design puts stresses through
the
substantial plywood components, which interlock in 3 planes. Beams,
and some stringers, are laminated for extra strength.
Long
straight fixed
keel
All the boats are built on a ready-made keel. This adds strength
to the hull, whereas a centreboard case is usually a weak point
(frequently the source of leaks), and it makes building faster
and easier. Compared
to a lifting centreboard with its associated case there are many
advantages
when sailing.
Much
more room where it counts - in the cockpit and cabin
A
steadier helm, especially in broken water or stronger winds
No
moving parts
One
fewer stressful job for the crew when launching and recovering
The
ability to keep on to windward in the shallows
The total
area is greater than the average centreboard, so windward ability
isn’t compromised, and
the ballast is as low as possible to maximise
the righting moment. Durable with minimum maintenance
The external hull surface is sheathed in glass cloth
and epoxy, and every wooden surface is saturated
with epoxy.
The hardwood
trim will
need a
fresh coat of varnish occasionally, but with this
minimal maintenance the boats will literally last a lifetime
(probably several!).
Repairs are far more straightforward than with a
GRP hull.
Stable / Ballasted
All the boats, except the 12’ Shimmy, can carry sufficient ballast
in the keel to be self-righting from knockdown. Combined
with the form stability this gives exceptional comfort and confidence,
especially
for the less experienced crew.
Simple effective rigs
Secret is designed for a gaff cutter rig, which
gives plenty of sail area low down and allows
all spars
to be stowed
in the length
of
the boat. The mast is
mounted on a tabernacle to allow easy lowering for
bridges, as it is on Stornaway and Scintilla.
Scintilla can also be rigged as a gaff cutter,
but is more usually equipped with the Scruffie
signature
rig – a loose-footed standing lug.
Scintilla and Stornaway have a small, unstayed,
mizzen for manoeuvrability,
enhanced flexibility
and a host of useful advantages.
The loose-footed mains are obviously safer than a
mainsail with a boom, especially when gybing, and
combined with
the wide mainsheet
travellers
allow the sail
to take up a naturally efficient curve both to windward
and off the
wind. Perhaps
their greatest advantage is that they allow brailing
lines on the mainsail, an idea borrowed from the
Thames Bawleys.
These
allow
instant depowering
and stowage
of the main (up against the mast and yard - out of
the way), simply by pulling a light untensioned line
from
the cockpit.
In the yawls
you are
then left
with a small sail at each end of the boat, giving
the ultimate in controllability.
The smaller boats have single unstayed masts for
the shortest possible set-up time.
The yard doesn’t need to be dipped when tacking – although that is
an option if standing a long beat.
Easy
to build – add
value!
Construction is described elsewhere, but anyone
can build a seaworthy and good-looking boat which
will
be worth
far more
than the cost
of the kit.
You can buy a secondhand
plastic boat, which will depreciate slowly, or
you can buy a kit and make money!
Timber quality
All the wood is of the highest possible quality.
Plywood is highly specified and closely controlled,
and from
sustainable sources.
Other structural
timber, mainly Oregon pine and Cedar, is also
carefully selected. Customers choose
the hardwood for the trim, from a range of beautiful
Australian species, and it is
that wood used for laminating structural beams,
with Cedar for lightness. |
