We are now in the tropics!  We crossed the Tropic of Cancer yesterday.   Celebration on board, with Virgin Marys all round, and even a crisp or two.  Music playing, "Gone Fishing" by Chris Rea, because Ben had another go with a rod, this time using a red lure to seduce those glitzy mid-Atlantic types.  The calls from some of the crew for sushi had been getting feral.  This time he got a bite but the fish got suspicious and sloped off, so no sushi.    But we were doing about 8 knots at the time with a heavy following swell, so maybe it was for the best.  We will try again when the sea is not so rough.
Today we are half way across, 1,400 nautical miles covered, and will be having a party at lunchtime.
Very starry at times last night with no moon and the Milky Way right across the sky.  We now have the Southern Cross low in the sky, and there were several shooting stars, including a big one one of about 75 deg of arc,

Some of you chaps might be wondering how we boaties manage for water for all
this time on the undrinkable briny.  If you are interested, read on.  We
have 1,000 litres of capacity in our water tanks, which were full when we
left Lanzarote.  We have a reverse osmosis water maker on board, which can
make about 300 litres of fresh water from sea water over a 4 hour period,
which is the amount of time we run the generator each day (it also recharges
the batteries).  This 300 litres goes into the tanks for washing etc, and
also for drinking.  This is a separate takeoff from the tanks into an
advanced microfilter system which takes out all nasties, and comes out of a
separate tap in the galley.
In addition we have two emergency backups:
1) Big bottles of fresh mineral water in the dinghy, which is the big item strapped down
on the foredeck.  This totals about 140 litres.  Every now and then we
decant one of these bottles into smaller ones and refill the big bottle
with water maker water.   Fresh water is somewhat nicer than water-maker
water (and pretty well all water on the island of Lanzarote is made from sea
water in the first place)
2) A hand water-maker intended for our lifeboat.  This can pump out 5 litres
per hour (or 10 litres if you are Jean-Claude van Damme)
Not bad eh?  We use quite a lot of the stuff - washing up, cooking, flush
loos (fresh water), and - wait for it - fresh water showers.
Back in the day the only fresh source will have been rainwater, and decks
were set up so that rainwater could be diverted to run the tanks.  We have had
no significant rain for 8 days, but as I type this morning we had a heavy
squall like a carwash which would have given a good few days'  top-up if we were reliant on
Cultural corner
“It’s been good being at sea these last few days.   The voyage calming and restful.   I stand at the rail for hours and look at the sea and the sky.  Why does the sea induce these feelings of transcendence in us? Is it because an unobstructed view of overarching sky meeting endlessly stirring water is as close as we can come on this earth to a visual symbol of the infinite?  I feel more at peace than I have for months.”
