I have been plotting the forms for the Guillemot Kayak using the offsets provided in Nick Shades book. I am having problems with form 1/2, 16, and 16 1/2. I am not sure if the problem is due to the way I am plotting the points, or if there is an error in the given offsets. For example, on form 16, after sorting the XY columes points X=.08 , Y=1.00 is drawn last and appears below X=0 , Y=1.56. This results in the form appearing incorrect. Below is the way I have ordered the set of points for form 16 after the sort.

(x ,Y) (0.00 , 5.25) (0.93 , 5.00) (1.00 , 4.97) (2.00 , 4.13) (2.05 , 4.00) (2.06 , 3.92) (2.00 , 3.65) (1.70 , 3.00) (1.00 , 2.11) (0.89 , 2.00) (0.00 , 1.56) (0.30 , 1.33 calculated diagonal) (0.08 , 1.00)

Can you see what I am doing wrong?
