THE NEW FERRIES - AN ALTERNATIVE
VIEWPOINT
Some time ago when the discussion
regarding the new Ferries had just started it was felt that people
might become unduly concerned. A letter was written to the Lymington
Times in an attempt to ameliorate the situation using the phrase, “I
feel duty bound to try to dispel the fears expressed by so many of
your readers”. The words were chosen carefully and the views
expressed have not varied in any respect.
Since then the
controversy has been developed out of all proportion by a
comparatively small group of activists that might best be described
as - the “Other Side”. They are not opposition, indeed
some are considered friends and, in all other respects, are held in
high regard. However, the views they express can only be born of an
unreasonable fear of Ferries or a lack of understanding.
The
following is an attempt, without trying to score points, to still
those fears and perhaps explain another point of view.
There
are only three factors of importance.
1. Safety. 2. Unchanged
continuity of leisure sailing and other river users’
facilities.
3. Protection of the Environment.
SAFETY
The
new ferries will undergo rigorous sea trials. If they cannot be
controlled properly in the river at low water (the acid test) - they
will be deemed to be unsafe and will not be allowed to operate.
Moreover, those employed to command these ships risk severe penalties
if they cause damage or injury. No ship’s master would sail a
ship that he believed he might be unable to control. If the new
ships are not safe they will not operate.
Claims
in respect to the supposed dangers presented by the existing ferries,
upon which fears of the new ferries seem to be based, are clearly
groundless in the light of the recently published BMT Group
report.
CONTINUITY OF UNCHANGED LEISURE SAILING
FACILITIES
In conversation with a highly respected sailor some
time ago the undersigned was reminded “You must appreciate
there are issues other than safety to consider”. As a member of
the R Lym YC for more than twenty years, a lifetime small boat sailor
and owner of a motor cruiser - his insistence that the leisure
sailors should remain unaffected by the new ferries is heartily
endorsed.
With the exception of “wind shadow”
effect, it is believed there is no reason for concern. No other
adverse impact that the new ships might have on the leisure sailing
community can be envisaged. If something is missed here - doubtless
someone will advise. Please don’t cite instances of being
thrust into danger or inconvenienced because the ferry has stopped
for navigational or operational reasons. Lymington is a port,
not a leisure centre. All proficient sailors know and understand the
Regulations for the Prevention of Collision at Sea. All should know
that the Lymington Harbour Byelaws state “The master of a small
vessel which is not constrained by its draft to navigate only in the
fairway shall not make use of the fairway so as to cause obstruction
to other vessels which can navigate only within the fairway”
All know that the ferries have been operating in the Lymington river
for generations before leisure sailors arrived. If a yachtsman or a
canoeist does not wish to co-exist with ferries in a commercial
waterway, he or she does not bring their craft into the Lymington
river.
Claims of the fear engendered by the existing
ferries are clearly groundless in light of the recently published BMT
Group report.
The BMT Group survey revealed some
startling statistics. In the last ten years “Incidents”
recorded by the authorities total 58. These include everything from
the most worrying, damage to a moored boat or a river mark (often
caused in high winds or dense fog) to less serious instances when a
near miss has concerned either a leisure sailor or one of the ferry
masters. This is extrapolated into the almost astonishing record of
0.045 incidents per 1,000 river movements. The report notes that this
record compares very favourably with any other similar statistic on a
worldwide basis.
Let us examine the effect of Wind
Shadow.
The increased superstructure of the new ships will result
in a greater lee or wind shadow.
There are two aspects
to consider:
1) When the existing ferry is southbound in Long
Reach with wind SW 4-5 (a typical situation) and a sail boat is
northbound - the boat will enter the ship’s lee, the sails will
flap, the crew will duck under the boom and, approximately 6 seconds
later - come out the other side to resume its progress. The new,
larger ferries will increase the period of wind starvation by 3,
possibly 4 seconds. The effect will be no more or less violent,
simply slightly more prolonged. It really is difficult to believe
that this is a contentious issue.
2) The other wind
shadow effect is potentially more far-reaching and revolves around
the effect ferries might have on Junior Sailing when the ships move
slowly in the upper reaches of the river. The issue is complex but it
is clear, in light of the BMT Group report that, with goodwill on all
sides and some sensible planning, Junior sailing can and will
continue wholly unaffected.
PROTECTION OF THE
ENVIRONMENT
This is the really contentious issue. Made more
difficult by the fact that even the experts seem to accept that much
of what is asserted on both sides of the argument cannot be cast in
stone.
The following personal assessment has been
reached as a result of what has been read, heard and observed over
some time.
1) The BMT Group survey recently published is
only the latest in a number of independent, professional, studies
into the operation of the ferries in the river and the possible
effect they may have on the environment. In summary, to date all the
expert opinion concludes that the Ferries have little, if any adverse
impact.
2) Independent studies of the south coast areas
of marsh have consistently concluded that the process of erosion is
natural and inevitable. Observation of adjacent areas, Tanners Lane,
Pennington, Keyhaven, and others, show all these areas eroded in the
same way as Lymington, some even more so, despite the fact that they
do not experience ferry traffic.
3) It is said that the
new ferries have the power to cause much more erosion than the
existing C class. That could be considered a possibility only if the
power available is actually used. The ability to couple up four
engines is a design feature of the new ships to ensure disruption to
the service can be avoided if or when a breakdown occurs or when
maintenance is undertaken. It is only necessary to use half the
engine capacity to operate the ship in the river. A Ferrari owner is
not compelled to drive at full speed past the Primary School at the
end of his road! Only the thrust required to safely navigate in the
river will be used.
4) The wash created by the ferries
is often cited as a major scourge of the marsh. Sadly, this
observation is usually made without any factual basis. For the most
part no discernable wash is visible in the wake of a ferry.
Occasionally, notably at low water, wavelets can be seen spreading
from the ship. Some weeks ago the undersigned commanded a Wightlink
Ferry that sailed at 1330, finishing the watch at 2150. During all
this time the wind was gale force 8 to 9. The weather station at
Hurst recorded gusts of 49 knots. At the commencement of the watch it
was high tide. The waves, a metre or more in height, were breaking
right across the marsh to the tree line, tearing at the spartina
grass, attempting to rip it out by the roots. As the tide ebbed the
waves broke directly on to the top of the marsh edge and gradually
worked their way down continuing to smash into the slope at 5 to 7
second intervals.
With some knowledge of what happens
in real life it becomes obvious that more damage is done to the marsh
in one SWly gale on an ebb tide than could be accomplished by the
whole of a Wightlink fleet, twice as large as the existing one, in
ten years of operation.
5) It is generally agreed that
the Ferries keep the river open in that they prevent it silting up.
However, the contention that the new ferries could increase erosion
of the marshes is vigorously denied. As pointed out above, all the
evidence is that impact is minimal. There is no reason why the
new ferries should have any more deleterious effect.
Let us try to
assess the effect of the ferries on the river. There is a strange
belief that the ferry thrusters squirt high powered jets of water at
the river banks over a considerable distance, thereby progressively
wearing them away. We all know this is not possible - yet the
superstition persists.
The following is what actually
happens. Close to the thrusters an area of turbulence is created.
This stirs up, into suspension for a period, the soft, loose silt of
the river bed. The quantity of silt involved depends largely upon the
height of the tide. At high tide very little disturbance occurs. At
low water, particularly in shallow areas of the river, occasionally
some discolouration of the water astern of the ferry shows that silt
has been dislodged. Much of this silt falls back from where it was
disturbed. Some will fall back upstream or downstream from its
original position dependant on tidal movement. Inevitably, some will
be borne out into the Solent and lost. We can only guess at the
amount. Could it amount to five hundred tons of solids in a year?
It’s doubtful - otherwise shallow patches developing in the
mouth of the river would become a problem. Whatever view is taken,
any supposed erosion thought to be caused by the Ferries can hardly
be compared with the sixty three thousand tons of river bed carved
out and dumped outside the Needles between 1 November 2007 and 31
March 2008. (See Local Notice to Mariners No.6 of 2007)
6)
A chart of the Lymington river dated 1891 in our possession is
instructive. It shows only (what is now) Oxey Lake - as marsh. All
the other areas are marked as mud. Large mud flats existed where the
Berthon and Haven marinas are now situated. A little Boat House marks
the site of the R Lym Y C. No moorings existed. Ironically, the only
really recognisable features are the public baths, the railway and
the ferry terminal.
When the marinas were established,
many thousands of tons of mud were removed to provide the areas of
water in which the boats now float. It is an inescapable fact that
with every tidal movement (four each day), hundreds of thousands of
tons of water continuously flow, round, over and through the river
and marshes to fill, empty and refill again these man made lakes.
SUMMARY
Nothing above is said in an attempt
to assign blame. It is not suggested that essential dredging should
stop or that reasonable development should not continue. There is no
dredging at Tanners Lane and the marsh there has been hugely eroded
in the last twenty years. One has to conclude that dredging may not
be as damaging as is sometimes suggested.
We are where we are and
from all the above it is impossible to see any case to suggest that
the existing ferry fleet is or has been dangerous or intrusive upon
the other users of the river, nor has it had any adverse impact upon
the environment. If the new ferries successfully complete their
trials, they will be safe, they will not interfere with either
leisure sailors or other commercial traffic any more than the
existing fleet. Finally, it is not believed they will represent any
greater environmental hazard than that which has existed for over
thirty years. On the contrary, we have every reason to believe they
will be more environmentally friendly. (Hopefully the awful soot that
our friends justifiably complain about so bitterly will become just
an unpleasant memory).
Of course the Other Side may well
say - “It’s all very well saying the new ships will be no
worse than what we’ve got - but the existing ferries are a
nuisance to us and this is a great opportunity to get rid of them
once and for all”. In answer, it is suggested that the
discipline of commercial operations imposes standards. It also
demands the acquisition of proper seamanship skills. Do we really
want to be seen as a group of people so rich, powerful and self
satisfied that we are above having to abide by regulations formulated
to keep all seafarers safe. The soft option is rarely the right one.
Despite the apparent attraction of becoming a floating leisure
centre, it is suspected that we would not breed Olympic sailors in
the atmosphere of the Serpentine.
