I


n high summer the islands
of Oléron and Ré, off the
west coast of France, attract
slightly more yachts than
there are visitors’ berths.
The very obliging harbourmasters
hate to turn visitors away, so they
cram the last few into berths
which are just possible to get into
but mighty diffi cult to get out of,
just like lobster pots.
I encountered a lobster pot
berth last summer in St Denis
d’Oléron: a fi nger berth, port
side to, on the north side of the
visitors’ pontoon. Our neighbour
to starboard was much smaller
so we had ample room to
slot ourselves into the berth.
Unfortunately he left shortly after
we arrived, to be replaced by a
much larger boat, which only just
fi tted into the available space.
Two days later we wanted to
leave for the 21-mile passage to
St Martin de Ré. Both harbours
have shallow entrances, restricting
entry and departure to slightly
less than three hours either side

of High Water. It would be easy
enough to make the passage over
high water, as long as we left at
the right time. With HW at 0400
and 1630, this meant leaving at
0130 or 1430. The latter seemed
more attractive. The weather
forecast was for a calm night and
morning, with the NW sea breeze
fi lling in early afternoon, building
to force 5 and veering northerly
by evening, a common pattern on
this part of the coast.
At 1400 we started securing for
sea and planning our departure.
The wind was Force 4 from NW
and building. The fi nger berth
was about 8m long, so our stern
overlapped it by some 3m, our
neighbours on either side were

‘How would


you escape


this ‘lobster


pot berth’?’

THE BOAT
IMPROVEMENT GUIDE
By Ian Nicolson, published
by Amberley at £14.99
This is another collection of
Nicolson’s bright ideas for
improving boats, illustrated
with his clear, simple
hand-drawn diagrams. These include a row
of clothes pegs for holding the navigator’s
notes at the chart table, and a ‘crash bar’
to stop you being thrown off the loo in
heavy seas. Some are more easily applied to
wooden boats than to glassfi bre ones, but
the principles can often be adapted.
Most people these days would buy a
custom-made solution rather than make
their own, but the ideas could inspire you.
It’s thought provoking and will grab the
imagination of any boat-owning DIY fans.

RYA INTERNATIONAL
REGULATIONS
FOR PREVENTING
COLLISIONS AT SEA –
2ND EDITION
By Tim Bartlett, published
by the RYA at £12.99
For Colregs to keep us all
safe, the skipper or master
of any vessel must apply the rules quickly
and accurately. That requires an intimate
knowledge and understanding of them, and
how many of us can say we have that?
For each rule, Bartlett gives a clear, simple
explanation of its practical application and
meaning, using both words and diagrams.
Available either in print or as an e-book, it
makes learning, understanding and applying
Colregs a lot easier and for that the author is
to be congratulated.

CAPTURE
By Colin Darch, published by
Austin MacAuley at £7.99
This recounts the author’s life
on all sorts of merchant ships
across much of the world
over half a century.
It’s a strange blend of tales
and anecdotes, but culminates in
the author’s accepting the job of delivering a
tug from St Petersburg to Singapore, during
which he and his crew were captured by
Somali pirates and held for ransom.
Surprisingly, Darch avoided retirement a
little longer and undertook a few further ship
movements. Throughout the book he gives
the reader an insight into a world quite alien
to most of us, even though the seas we sail
are the same. In that sense it is ‘enlightening’,
but it is not always an easy read.

about the same length. The width
of the navigable fairway astern
of us was not much more than
one boat’s length. The handling
characteristics of our boat are
determined by her hull shape: a
long keel which is very shallow
at the bow sloping down to the
deepest point just forward of the
transom-hung rudder. The rig
is slightly unusual, an unstayed
cat ketch with a bulky carbon
mainmast about half a metre aft
of the stem and a slightly smaller
mizzen just forward of the cockpit.
It works well under sail but under
power the combination of a lot of
windage forward, with not much
underwater area to stop the bows
being blown to leeward means

that she has very predictable
handling characteristics, which
make for an easy life if you plan to
work with her turning preferences,
but a hard one if you don’t.
At 1430 we were ready to go.
Now you take over. There are a
few other things I should tell you
about the boat. She has vane
steering gear which projects about
1.5 metres from the stern and a
stubby platform bowsprit, about
1m long, on which the anchor is
stowed. The stern kicks hard to
port when going astern, gently to
starboard when going ahead. You
have only one crew member, but
she is strong and agile. W
