That’s that, for the moment: new lockdown, can’t go to the boat for an autumn mini-cruise or even to do some maintenance, so sum total of this year’s sailing is 5 days in the Solent. I try not to contemplate the cost per day.
We have however decided to leave the boat fully in commission in Chichester Marina (above) over the winter and into next season, with sails bent on and engine not winterised. This is because Spring Fever was launched only in mid-September, so gear and antifouling have not just finished a long, hard season.
The British government turns out to have been ahead of the game on the satellite risks I mentioned last month, with a £36 million programme just announced to prevent navigational satellite failures damaging the economy by as much as £1 billion a day. It is feared that the entire country has become over-dependent on a handful of satellite systems.
Emergency services, the energy grid, mobile phones, Satnav, broadcasting and other communications, the Stock Exchange and an array of other activities all rely heavily on the super-accurate timing provided now by navigational satellites such as GPS and similar systems. There are life-threatening risks from failure, says the government.An image of a third generation Lockheed Martin GPS satellite
The new investment is in a National Timing Centre to create a network of super-accurate atomic clocks around the UK, accessed through ground-based communications, so that the economy will no longer be over-reliant on timing from GNSS signals from the sky.
GNSS is the term that embraces the US GPS, the first system, Russia’s GLONASS satellites, Europe’s new Galileo and also a rapidly developing Chinese system.
Galileo failed completely for a while last year during its start up phase, because of operator errors, and there are now many examples of interference with GNSS systems and malicious ‘spoofing’, in which navigation instruments are fooled into thinking they are somewhere else. The heart of all navigation by satellite is accurate timing, without which positions cannot be fixed.
Spring Fever was taken out of the water on December 16 and put ashore at the Kingston yard in East Cowes, where we are planning to leave her until May. Idle thoughts now turn to planning next year, and to Spain.
We have given up our pontoon mooring on the River Medina for 2020 because we plan to stay away from the Solent for the whole season and it will be cheaper to take a visitor mooring for a few weeks before we leave than to pay a whole year for our own. The conversation is increasingly focussing on the wonderful hills and Rias of North-West Spain, though we do not need to take any decisions for a few months.
