You are so right, I have found it really difficult to estimate distances over water. I have some new charts for Kylesku, Ullapool and my own area of the Moray Firth. When I am up in Scotland again in a couple of weeks (I can hardly wait) I will check out known distances on the charts and then take a look from the boat. That way I should get some practical estimation at known distances (what a mouthful).
NO not TOYS, I've been very working hard to convince the Boss (her indoors) that these GPS thingys are a VERY important and necessary life saving instruments that are required by LAW and if I don't have them I could drift out to sea and never be seen again etc. etc.

Of course I got the charts from www.chartsales.co.uk,
