The
First Icebergs
Despite the fact that Olivier de Kersauson and
his crew were as far north as 53° South, Geronimo
encountered her first icebergs last night: something
of a surprise in these latitudes. "It's a
bit worrying. You very rarely see them this far
north, except in years where there's a lot of
ice break-up. Coming across ice here with relatively
high water temperatures of between 7 and 10°
sent a bit of a chill up my spine, I can tell
you. It's a pretty alarming thing to happen, but
sailing conditions are very unusual at the moment.
To the north, there are cyclonic systems that
we simply can't go near and to the south, the
weather systems are extraordinarily complicated.
We're being buffeted about between persistent
high pressure regions and southerly depressions
trying to move north. The result is uncomfortable
seas, squalls and turbulent weather systems with
fronts. If we're going to get ice as well, we'll
have the full set! For the last 24 hours, it's
felt as if we're really struggling to be where
we want to be and find a latitude where the boat
can really glide. It feels like everything's against
us".
The means of detecting icebergs and growlers are
as limited during the day as they are during the
night. "What poses the greatest danger to
us is all the chunks of ice that come off the
icebergs or float just below the surface of the
water. Only 10% of the ice breaks the surface.
For example, a block of ice 100 m3 in size only
shows one metre above the water. It was simple
with slower boats like Sport Elec. A trimaran
like Geronimo is travelling at 20 knots or more
all the time, but the technical resources we have
to detect ice aren't very different. There's also
an element of luck in all of this, so we're paying
very close attention, because if one of these
hits the carbon fibre, it's going to be a drama!
When the sea is high and waves are breaking at
5 or 6 metres, there's no way we can something
just a metre high until the very last moment.
So it's all a bit nerve-racking. When we get ten
degrees or so further west, the danger will be
less. But we've got to keep at it!".
The Cap Gemini and Schneider Electric trimaran
is currently travelling rather slower than previously
at between 20 and 21 knots. "For the last
7 or 8 hours, the wind speed has dropped to between
23 and 24 knots. There's not a cloud in the sky
and visibility is excellent, unlike this morning
when we were amongst the ice. We had no more than
4 miles visibility at best".
