How long is a day? Obvious really – 24 hours. But only obvious because we learnt it at school and we have accurate time pieces that keep track of time to within thousandths of a second a year.
Anyone who has taken a long haul flight from East to West or West to East will have experienced the shift in time between where they boarded and where they landed. Get on a plane in London in the morning, get off in New York 7 hours later and its still morning, although your body clock tells you otherwise. Has time reall stood still? No of course not its just different time zones, ensuring that day and night in different parts of ye world all occur during the hours of light and darkness.
Travelling just a little South of West, we see this effect every day. For every degree we sail west, the sun rises and sets 4 minutes later every day! To compensate for this we can change our clocks to effectively move ourselves into a different time zone whenever we want.
But what about the ancient mariners who relied on the sun for defining their time and for navigation?
Local ‘noon’ or the point at which the sun is at its highest is frequently used as a time for navigating with a sextant, and many things on a ship are based around sunrise and sunset, all of which as we have said above differ by 4 minutes a day for every degree we travel East or West. Sunrise and sunset are also effected by latitude and time of year which must have made it very difficult for those ancient mariners to have a consistent ‘day’.
One thing is for certain, I would have wanted to be sailing East not West, because based on the above the days would always have been shorter so less time between meals!
Our last day has been quite pleasant. We are in the South East trades now and our speed has been quite reasonable – we covered 189 nm during the timed 24 hours (and due to the fact I am writing this a little later and we have had a cracking last 12 hours overnight covering 105 nm we now have less than 2000 nm to go, and we are over a third of the way).
We had a deck full of flying fish and squid this morning so I got the ‘cruisers guide to fishing’ out and looked up how best to utilise the squid as bait!
I had already dropped in one normal lure and unfortunately with a quick scream of the reel, something large took the lure, the stainless trace etc. and snapped the line mid length – very strange indeed, but maybe it had been snagged on something which gave me an idea – ;ets have a ‘Squid Off’. Plastic versus real (well used to be real but now rather dead). So on one rod the carefully prepared dead squid was trailed and on the other a plastic squid lure. It was a bit uneven since the plastic lure was about 4 times the size of the real one, but that ink and other goo to attract the predators so each had their own USP.
First blood (well bite) went to the plastic lure within less than 30 minutes but the hook wasn’t taken. Then the sun came out brightly, which in my limited experience means a sinking lure is a better bet than a surface one and both these were surface lures. There was no more action until just after lunch when the reel with the real (dead) squid started screaming and we landed a small female Mahi. It was certainly big enough for several meals but having caught several Mahi before and realising just how young this one must be we returned it to live another day. By dinner time Lesley was somewhat regretting the decision since its a while since she has has fresh caught Mahi, but on balance it was probably the right thing to do.
So which was better? Inconclusive, but the plastic ones are far easier and less mucky and less smelly to prepare!
We saw no boats and no wildlife today but we did see some shooting stars in the partly clear sky. Other than that not much has changed. Apart from a few rolls of genoa in and out to match the changes of average wind strength the sail plan has remained constant. The regular checks around the boat have revealed nothing more sinister than a broken lower guardwire across the gate to the bathing platform (trivial, not used at sea and easily fixed with a short length of dyneema) so things are holding up pretty well.
All is well onboard.
