I woke in Badachro to a flat calm - mirror finish on the water. So a leisurely start, and dropped the mooring at 11:30.

As I motored out of Loch Gairloch, I realised I was in completely slack water, no wind or tide - an ideal opportunity to finally calibrate my water speed log. Raymarine has a facility to instantly set the water log to whatever the GPS is currently reading, but given the GPS averages the previous couple of minutes and the water log is instantaneous, that's a bit error prone. I prefer to log distance through the water over a measured distance by GPS, and take the ratio. If there's any current or tide, you then reverse course and take the aggregate thus cancelling out the tide. I was pretty confident it was slack water, and couldn't be bothered(!), so did it just one way. I got a correction factor of 1.25, which is quite large. I knew it was under reading, but hadn't realised it was that bad. Since applying the calibration, it's giving much more plausible readings. Another job done!

Entering Loch Torridon the scenery was imposing ... and draped in particularly Scottish weather!

I came to the anchorage in Loch Shieldaig - an offshoot of Loch Torridon, sharing its name with a similar offshoot of Loch Gairloch just to the north. Confusing!

I misjudged my first drop of the anchor, and ended up a bit close to the rocks for comfort. Evidence was easily hearing the conversation of the swimmers resting on the rocks! Up it came, and second time was perfect.

I spent the evening installing the upgrade to my Raspberry Pi navigation set up. Fun and successful.
