Todays quiz
This is from the Brian Toss rigging book so if you want to cheat, you
can look it up. If I string a line around the equator (disregarding natural obstacles) and then decide I want that line 1 foot above the equator all the way around, how much longer must that line be? Call the earth's diameter an even 8000 miles. G |

Ooops, just noticed I only increased the elevation by 6", so change that to 2pi feet. same principle. Cheers Martin |

From reading all the varied answers so far, one can make the conclusion
that one should always carry more spare line than they think they will use in every situation...then one doesn't need to worry about things like this...or as the AScouts say "Be Prepared". |

Over the thousands of years men's brains evolved to understand distances and relationship between points on a globe.
