Please note the given location is not the cache location,
but just one of many cryptic clues.
To find the cache you have several pieces of information at your
disposal. You may find a map, some note paper and your brain
helpful.
First Clue
The first clue is the lat/long of the start of the line:
N 54° 26.197' W 0° 33.585'
Second clue
The next clue is a riddle:
My first is Raw, and my last is the man that is the opposite
of raw.
But before you set out you'll need to know some more.
Look halfway along a line between these things to find me.
My last is not a chef, but is a man of the sea.
It was not far from here the man first drew breath,
but halfway around the world that he met his death.
Many times he sailed the seven seas to secure his fame,
And now stone and bronze honours his name.
Third Clue
The next clue is the lat/long of the geocache. Unfortunately I'm
only going to give you part of it:
N 54° 2*.*75' W 0° 3*.*42'
Bonus Clue
There is also a bonus clue. You don't have to solve this to find
the cache, but it might be useful. But to read the clue you will
have to apply a substitution or Caesar cipher to this text:
YtkNsirdqfxyqttpfgtajfsibjxytkPDgjwufxx
djyNyxyfsixstytsxstbgzybjqqyjsijilwfxx
NkdtzhfsykNsiqystbDtzsjjifpNhpNsymjfwxj
To find the number of letters to shift backwards, the number you
want is the last digit of a thing which has a unique number at the
lat/long of the start of the line.
