Thanks Frank. I saw most of that the first time. I just wasn’t sure what to do between noting the direction of my thumb and finding a north point on my horizon. I tried to go over the top of the celestial sphere to the horizon behind me. Substituting a card is easier to understand. Just look horizontally along the card (See diagram). This does beg the question; the card probably won’t be vertical, except at merpas, so how should you look along the card to find a point on the horizon? Should you follow the slant of the card or go straight down, but therein lies the path to madness, so let’s not go there.
I have actually steered by Polaris (at least I hope it was Polaris). My first ever night passage in TIKI motor sailing up the coast between Spurn and Whitby, the light failed in my compass. I found that if I kept Polaris just off my starboard spreader, I got the course I wanted without spoiling my night vision by shining my torch at the compass every few minutes. DaveP
