Dead men voting? Ok, it's all coming back to me now.

I think Dead Reckoning was an ancient form of navigation once practiced by long-ago deceased mariners? I believe the navigator used a specially matched set of chart darts which, when thrown at a chart hung on a convenient bulkhead, indicated the approximate position somewhere within the triangle described by the darts.

I'm pretty sure that is what it was . . . . . . . or maybe it's that 'Deduced' thing someone was talking about earlier . . . . .

I will have on board all necessary paper charts to navigate in any point of the Brazilian coast or any other country as I get there. Electronics is good but it does not hurt to back it up on paper every now and then....

For those who think these phrases are just more TF nonsense...

C
an Dead Men Vote Twice

Compass heading +/- compass Deviation = Magnetic heading +/- magnetic Variation = True heading

Let's not forget ANDS. More of an issue in an airplane than in a trawler where speeds are relatively constant.

Accelerate North Decelerate South

(as one accelerates, the wet compass swings toward the north)

yeah...but who just did a 6-10 hr voyage in the pea soup fog with just a compass and a chart and a stop watch?

Cool to talk about it...it's another to do it.

Google "Honda point disaster". September 8, 1923 was the largest peace-time loss for the US Navy while DR south from San Francisco to San Diego. The fleet turned east when they thought they were clear of Point Conception. However, they were still quite some distance north and wrecked on Point Honda.

"Add Whiskey" is a variation of that.
