I threw that protractor/string/weight in, almost for laughs. Say the protractor was divided into degrees, and half degrees, 30 minutes of arc equaling 30 NM. Could one estimate 1/4 of a degree, which would be worth 15 NM, I believe. I don't know, however any fixes obtained would be pretty loose, I think.
All this leaves us where. Strikes me that absent electronics, one had best get some practice using the sextant. As for the other devices you mentioned, I have seen/read references to them and their down sides. I have no idea as to the accuracy that might be expected using them.
