from David.....
While sitting in the boat going up and down like a Big Dipper I realised that, while I had watched auto helms (George) used for probably 30 years and, until coming out of Lowestoft, I had never used one in anger. In the early days of my sailing Seamus used one which he switched on and then adjusted direction by pressing two buttons – one to Port, the other to Starboard and, although I never used it, I thought I probably could have managed!
Since then technology has advanced at phenomenal rate with advances in computer technology and things like Chart Plotters. Not only has navigating become automated the theory is it has made life easier and safer for the sailor (although I do believe in having paper chart – I am old and believe in belt and braces) - or so they say! You can actually plan the route to your destination, put in waypoints (either as one long string or, as crossing the Thames Estuary, a series of short “passages” all linked together) and get George to steer you to your destination. Piece of cake!!!
Stuart fitted a Chart Plotter based on electronic charts downloaded and paid for via the internat. Into this he connected and AIS receiver (this picks up a signal from ships that give name, call sign, direction, speed, nearest it will come to you, wipes your backside etc. etc.) and attached George. Now this is not your old fashioned George. Not only did it work the same way the old ones but it could talk to the Chart Plotter and adjust the course as necessary.
All of this is perfectly clear to sailors that have this type of equipment or are really into computers.
Now, having survived my 1st solo from Lowestoft to Shotley and having had Stuart set up the Thames Estuary crossing on the plotter, I headed out with great trepidation. Motored for an hour steering by hand and then decided to hand over to George while I made breakfast.
I fixed the steering arm to the tiller and started going round in circles – no red lights showing or winking - I had assumed that George was powered from the same switch as the plotter but clearly not. I retired below and could not see which switch activated him so decided to talk to the expert. Stuart, like all sons, was very tolerant and told me which switch needed to be on – the socket one on Instruments as I had assumed!
Red lights, blessed red lights, flashing! So I pressed the engage button and we headed in a single direction – towards Holland. The turn left or right button still wanted to go to Holland; after a couple of circles George still wanted to go to Holland. No matter which button I pressed the boat was going to Holland.
When I explained this to Stuart on my second panic telephone call I could hear him laughing his head off. It was some moments before he could control himself enough to talk me through the process of connecting the plotter to George in the right sequence – generally it helps if you tell the plotter which route you wish to use (preferable prior to telling George to navigate).
George did a good job after that until I decided that he had not done gone through a waypoint – but that’s another story.
Still in Ramsgate and, while the weather is improving, it will not be sensible to sail until next Monday so I am heading back to Chepstow to see the family – not to mentions the dog!
