That's not what was asked - he was asking about chart plotting/passage planning at planing speeds, not passage making at planing speeds.
On my APB we pre-planned the route during the day, had route cards which were laminated (but we had pens/chinagraphs to make any changes), went to Beaumaris for Fish and Chips - and my leg was to nav the Swellies, in the dark, on Low Spring Tide, with timings for 10kts, 15kts and 20kts - keeping to 20 kts as the baseline......
The best bit was that the Mrs was driving - and she had to do exactly what she was told, exactly when I told her to do it,
And she did!! Ah, the memories...
We also had the full charts with us in a waterproof bag - so when the next crew ran very shallow off Port Dinorwig, we went into the marina and tied-up, re-planned the leg on the pontoon to take into account the slightly shifted sandbank, and then completed the run back to the start point. I think we all passed...
