Main hull stringer layout - string lines

 using string lines to check the fairness of stringer alignment,

in preparation for notching

 first divided by tape measurement and pencil between the keel and waterline +3"

as per plan notation

 then put a small screw at each stringer/frame crossing pencil mark,

then ran a string line for each stringer between the screws

by eyeballing the string lines, small corrections needed to fair the alignment could be easily made,

and the symmetry of taper of several stringer alignments checked  simultaneously
