: when i built my s&g guillemot i read the building logs that both Nick and
: George Mcquade wrote. they were very helpful.
: this might help.....
: lets use 'position 20' as an example.
: width 0 is the vertical center line. the very top point of the deck at that
: point is 6.55. this is the height above the design waterline. height at 0
: on the keel is a negative number because it is below the design waterline.
: the sheer measurement is 5.4 inches out horizontally from the vertical c/l and
: 2.23 inches above the waterline.
: hope that helps;
: daren.....

It helped me immensely The reference point's is exactly what I was missing. With that information my CNC experience will help immensely, as it now becomes the same thing as referencing a vice with an edge finder.
I had completely overlooked using the water and center lines as my reference points even though they where mentioned in the articles I read on drafting. Kudos to you Daren... Thank you sir.... May the boat Fairy shine blue sky's and appealing water upon you and yours.
