Have a question on drawing the frame reference lines. Do I measure from some point?? I am looking at the plans and do not see any reference distances on the plans at all. It just says "Draw the reference lines as shown on the frame reference drawing" I see the lines and the x's at the tops but how?? Please help, stumped and stuck at this point right now.

Dickie you should have a drawing marked "Frame Ref" that gives you straight line mesurments for frame location. HTH

That sheeet never printed out! Have it now, thank you Bronco

Confused me too at first...I'm building a Freedom 13. On mine, and I guess all the other plans, the measurements are from the edge of the panel, which suggests the panel better be perfectly square and true!

I used a 36" long T-square, like a draftsman (oops, drafts-person) uses (oops, used to use) and marked my lines every 12" along the way...problem with that was, when I did it from the other edge, the top of the line (36" from the bottom of the panel) would be off by a couple of mm. I solved this problem by ignoring it, like I do a lot of stuff. I sketched another line from the other side and kinda split the difference.

I found a nice metal "yard stick" at Lowes with inches and mm's on it which I used to find my points. I'm currently glassing the boat, so I guess it all worked out ok.
