This is in the interest of assuming you have no source of electronics.
It would be a lot to try and keep track of on a small boat, but, how inaccurate would keeping a log of distance using a some sort of chip log or mechanical knotmeter and a watch for estimating distance.
Could a system not be adjusted for error over time using modern equipment until you had a fairly accurate number that could be used in the case of no electronics?
What would be the best way to go about it?
There really doesn't seem to be much in the way of alternatives to get distance un-electronically on a small boat.

Chip logs are very accurate and easy to make, and a good way to calibrate electronic logs.
May i refer you to the details to our book on Emergency Navigation. It has all the analysis and options covered.
We also cover the subject with practical exercises in our Emergency Navigation course which in many ways serves as our "advanced course" in several subjects, including cel nav, coastal nav, and weather.
