Your allowed 3 lines per person(licensed). In my opinion not to undermine traveling mans is 24 inches per side. I have seen people run there planar lines of big jon triple trees that are a mere 2 to 3 inches apart from one another. they also make planar board specific line that you can order offline or find in practically any lake side tackle shop. However I know that my father used masons line like your speaking of but it tends to rot out faster. Hope this helps.
