M_Boats: Rigging the M15

Hi, all. I'm new to sailing and likewise new to the M15. I inherited mine from my grandfather who passed away a few years ago, who never had the chance to take her out. Her running rigging was in very poor shape, and I can't quite figure out how (and where) everything was intended to be connected. I got the mainsheet and halyards sort of figured out enough to take her out on the water last year once, but I's pretty sure it wasn't quite right. Does someone have good documentation on how the M15 is rigged? Also the lengths and sizes of line that I should buy to get it back to new? Thanks for you help, Alex Matthis Sail #281 Portland, OR
