    Re: 'Intentional Error' Method of Navigating to Destination.
    From: John Huth

    Yes, this is actually a pretty common technique.   The main issue is that finding a line is much easier than finding a point.    I've heard this referred to as "deliberate compass error", but it's the same idea.  

    Finding a one dimensional object - a road, a river, a coastline, etc is easy as long as you know the general heading to that.   If you have a specific heading to a location that lies along that river/road/coastline/trail, you make a deliberate offset, so that when you come across that river/road/coastline/trail, you know which way to follow it in order to make it to your destination.

    I've done this numerous times, kayaking in the fog off the coast of Maine.   I might want to his a point on the easternmost side of an island, but if I miss that, I'd end up paddling out into the open ocean in the fog, which isn't a good idea.   So, I make a course for the shore of the island, knowing that once I reach it, I only head east.  

    Gatty's example in Siberia is one of many.   This is definitely up my sleeve in my bag of navigational tricks. 

    It reduces the two dimensional problem of navigation across a surface to a point to a one-dimensional problem.
