Photoluminescence
Tonight we are sailing from Cartagena
to Cabo Del Gata. It is a beautiful night. The weather is settled,
and we are moving under sail. There are barely any waves out there.
All the stars are out, in a way they could never be closer to land,
where there is the perpetual light pollution. When looking at our
wake, we can see tiny specs of light. The SaltyPaws is disturbing the
water enough for the tiny algae to give up their light. The water
needs to be moving in order to see the effect, and the first time I
saw it was when we needed to re-anchor in a storm at night. The water
moved sufficiently to make the lights come out. Another good spot to
observe the light is when using the toilet in the dark. For the more scientifically inclined, the chemical reaction involves the oxidation of Luciferin* . While related, the name doesn't come from any devilish origins, but rather the latin 'lucifer' meaning "light bringer".

Crossing the 0 meridian
Way back when crossing any meridian
was a Big Deal. Before people had reliable gps units, even before the
gps units where made out of wood, people would tell the position of
their ship using a sextant, and accurate time peace, and an almanac
with the location of the heavenly bodies. Using this method, it is
easy to work out longitude, by measuring the highest position it
will take up during the day. For latitude however, the time piece is
needed, as the only way to accurately measure latitude is to
compare the 12 o'clock at Greenwich, with the local 12 O'clock. Telling
time accurately was therefore a big deal, and smart people at
Greenwich finally worked out how.
This time we Crossed the 0 meridian in front of Cartagena. As the GPS did the navigating, we barely noticed.
Not that the crew was told the
positions accurately. As old superstitions still held with some of the
sailors, the captain would usually report less progress than what was
actually made. This way, the sailors would be less scared of falling
off the earth.
The first time I crossed the 0
meridian, I was sailing from Belgium into London. Right in front of
the O2 stadium, the gps reported 0.0000. Quite coincidentally, this is
the closed Greenwich that you can get by boat.

In the wake of the Volvo Ocean race
On the SaltyPaws we have been closely
following the Volvo Ocean race. What makes the race even more
exiting, is that the first leg, follows the route of the SaltyPaws
for a long time. The main differences are: SaltyPaws anchors when the
wind is not favorable, or starts the engine. The other main is the
coffee and the food.
In order to catch the wind, we stay offshore quite a bit when we are passing the spanish coast line. Just as the girls team did in the race, we head closer to shore near Marbella, in order to avoid the strong current through the Gibraltar straight.
The first leg of the SaltyPaws was
from Alicante to a small nature reserve called Isla de Tabarca. We
tried to make more head way the first day, but we decided that
beating against seven Beaufort was simply not worth it. We circled
the island and found a good anchorage.
The next leg is from Isla de Tabarca
to Mar Menor. We started out with a good half wind, but gradually the
wind lightened, and shifted
We found a really quite anchor spot in
Mar Menor. While all sides of Mar Menor are built up solid, this
little island just had a few signal towers. Without any waves, and a
very light wind, this was one good night for sleeping. The water
looked very attractive for a swim, until we saw it was jelly fish
infested. There is a current going into the Mar Menor, fueled by the
evaporation, and drawing the jellys in. Once they are in they are
there to stay, until it gets colder. The natural predators for the
jellys are sea turtles. It is unfortunate that they are so scarce, as
right now we could have used a few.

Atlantic crossing - Update 17 November
A small update to the maps, the distance to St. Vincent is now shown, although I am not sure if that is his actual destination. :) But if it is, there is "only" 940 nautical miles remaining from the original 2590 NM.
Apologies for the hardly legible dates but it's out of my hands!
