translation of seine twine sizes?

[rickc]

For those of us stuck in the prairies of Canada far from the sea the question remains wh\t do the sizes of twine represent. Brion Toss catalog lists 20, 40 etc as size but what does that translate to in everyday units
Thanks

Hi again,
Oh that. #36, the most generally handy one, is about 1/16". #72, suitable for beefy jobs, is about 1/8". For your boat, I suspect that #30 and #60 might be right, if you only had two sizes. At the very least, using those two would help you calibrate for your ideal.
Fair leads,
Brion
