It is the first day of summer (in some people's reckoning) so, naturally, we had the stove going.
Rewinding slightly ... at Watford Locks we joined a queue of four boats waiting to go down. There was only one boat coming up, and that was near the top, so it wasn't too long before the southbound boats began to move. I did expect the boat we were behind to shuffle up as the queue moved, but it stayed put. It transpired that the crew were complete novices, having just bought the boat at Crick. It appeared that the two miles they had just travelled to get to the locks was the only boating they had done. When the last boat ahead of them disappeared into the top lock I thought that they would surely move now. But the skipper had gone with the lockie into his hut. His crew explained that they had discovered that they had no windlasses. After a short while the skipper returned with a windlass given to him by a boater in front. They got down the locks OK; we followed and didn't see them again. Derek and Judy on Firoza were following us.
We tied up behind Dane and Clara just below the Admiral Nelson; then we walked to the Boathouse pub for a filling carvery.
On the way back Jan noticed something to make Nev weep.
his blog.) It would appear that the message about avoiding cutting or strimming close to boats hasn't got through to all of CRT's contractors.
I looked at the little "traffic light" tell-tale indicators on all the batteries today; all four were showing green. This was very pleasing to see. This, too, would seem to indicate that I haven't actually killed the batteries (when the alternator wasn't working) after all. So I probably don't need to replace them. So I will probably tell Midland Chandlers, who are holding a set for me at the Crick Show price, that I don't need them after all. And my wallet will be correspondingly heavier.
I had a look at the Adverc website in my quest for a means of regulating the alternator a bit more. The external regulator Adverc does seems to be similar to the Sterling device that I disconnected, in that it takes a feed from both engine and domestic alternators. Having separated the two charging systems I don't really want to go down the combining route again. I want something very simple, just to hold the alternator down to 14.4V once the bulk charging has happened. I have experimented with inserting a (forward-biased) diode in the feed to the small + terminal, but nothing happened apart from the diode getting warm. I might try a beefy transistor with a zener diode limiting the voltage. Something for me to think about tomorrow ...
