REPORT
Alinda V is a beautiful 24m classic ketch, designed by Alfred Mylne and
first launched in 1934 by Alexander Stephen and Son in Glasgow. She
has since spent long periods in Eastern Mediterranean waters. In 2009
her owners decided it was high time for her to have a major refit, including
extensive work on her interior, machinery systems, hull structure, deck
fittings and rig. Photos courtesy of Southampton Yacht Services and
Grama Blend.
Southampton Yacht Services have carried out
major refits of a whole range of large classic sailing
yachts over the last 30 years and were delighted to
be entrusted with the work on Alinda V. The
interior had deteriorated and in addition, the
engineering had suffered over the years. In
addition, the rig – which had been altered to a
Bermudan ketch in the 1960s – was badly in need of
replacement. The project team’s planning of such
an extensive refit is extremely important, so that
a careful balance can be made between retaining
the classic features of the yacht, and simultaneously
incorporating modern comfort. The shipyard
successfully completed the challenge; re-launched
August 2010, her classic lines now hide a multitude
of modern and practical engineering solutions.
Together with her new fixtures and fittings, these
ensure she is perfectly equipped for life in the
twenty-first century.
Complete Strip
Once the yacht had been placed undercover and
was stripped-out, it was clear that her hull
structure, beautifully built of galvanised iron
frames and teak planking, had stood the test of time
extremely well. The fully stripped hull was carefully
prepared and re-painted prior to installation of
tanks. Having stripped and cleared everything, the
inside of the hull was scanned and fully engineered
in CATIA CAD software. This produced a complete
and accurate 3D model of the inside of the boat,
enabling the careful planning of system
installations, according to the very best use of
space.
Careful space-allocation was especially crucial
in the rebuilding of the engine room. On Alinda V,
the engine room stretches to the full height of the
deck, originally with a skylight above. Her
sistership, Eileen II, still has this arrangement, but
on Alinda V the engine room skylight was changed
into a ventilation box with seating above. This
hugely improved the use of deck space and also
enabled much better sound-insulation of the engine
room. Furthermore, the original engine room
arrangement included a bulkhead, dividing it from
the owner’s accommodation which had a step in it.
The new general arrangement was worked out so,
that this bulkhead could be flat - also making the
job of sound-insulation and pipe runs much easier.
Space Saving
The new engine room is slightly smaller than the
original, but houses much more equipment.
Additional equipment includes chilled water airconditioning, two generating sets, two watermakers
as well as all ancillary equipment. To fit all
necessary equipment, the batteries were moved
forward, out of the heat and correcting the
longitudinal centre of gravity (LCG). The engine
room is quite short and fitting the engine while
maintaining good access for maintenance took
careful planning.
Ventilation to engine rooms in classic yachts is
always a challenge. With the new configuration, air
is drawn into the room via dorades and deck
mounted cowls, and through a snorkel on the aft

engine bulkhead. Warm air from the engines is
extracted through the base of the seating area
constructed over the original skylight position. As
a result, the noise emanating from the engine room
decreased significantly, even though it now
incorporates a much larger amount of equipment.
Traditional Deckhouse
The deck had been altered over the years and
water-leaks through the decking had caused serious
degradation of much of the deck steelwork. The
team decided to rebuild the deckhouse following the
original design closely, but with slight changes to the
dimensions. The new deckhouse was reconstructed
according to the original style, using traditional

techniques. It now is however mounted on a new
stainless steel supporting-structure that is securely
fitted into the deck beams. The deckhouse was built
from one log of teak to ensure good colour
consistency, and features traditional mortice and
dove tail joints in the corners. In addition, all the
original moulding features were carefully copied.

yard, the joinery had suffered from many years of
heavy varnishing and painting but it was agreed to
follow the original style, which resulted in the use of
new oak panelling and mouldings similar to the
original. The oak for the panelling was selected to
have distinctive figuring, and was complemented by
solid sections of European oak. Lightweight granite
and marble surfaces were fitted to the heads and
galley and traditional taps and fittings were chosen
to complete the time-honouring atmosphere.

a 1930s feel.
Easy Anchoring
A subject of much discussion was anchoring.
The expected use of the yacht requires frequent
anchoring. Before the refit however, anchoring
required a number of people, because she carried
a traditional fisherman’s anchor on a catting davit.
Sistership Eileen II was successfully fitted with

anchors in hawse pipes to overcome this, and the
same was decided for Alinda V. The result does not
weaken the aesthetics of the yacht and greatly
improves the ease of anchoring.
A common challenge during refits of classic
yachts, is how to deal with navigation equipment.
Modern electronic equipment is often difficult to fit
on a classic yacht. The refit team decided to fit the
Grama Blend
The yacht features wonderful natural stone,
to add a touch of real natural beauty and
magnificence to the interior. New lightweight and
conventional granite was installed to the galley
top, for its unrivalled durability. In the cabins
lightweight marble was used for the vanity tops,
bathroom floors, shower walls and shower soles.
Grama Blend lightweight stone was specified for
its incredible lightness, thinness, strength and
ease of installation. Installation was carried out by
Southampton Yacht Services own joiners, with
the backup of Grama Blend’s technical support
and on-site guidance.

were mounted on both sides of the helm position,

helmsman to have access to all crucial information,
without leaving the helm position.
