conundrum

[Phoenix of Hamble]

A hand aboard a ship I knew
Could measure angles fair and true
Without a sextant or nautical aid
How were those calculations made?

if you extend arm towards target, the width of a closed fist is approx 10 degrees, the width of an open hand (thumb tip to little finger) is abt 15 degrees.

Is it really that simple......? /forums/images/graemlins/grin.gif/forums/images/graemlins/wink.gif

...and it follows that the "valley" between knuckles is approximately 2 - 3 degrees depending on the size of your fist.

 

[Talbot]

compare it with a hand bearing compass one evening while at anchor enjoying the calm unspoilt nature of our world (must stop taking those drugs)
