: I do not completely understand how to read the "offsets" table. Are
: the measurements from the bottom and from the centerline or from some
: other reference point? Thanks for your help.

depends on who puts these things together. Some plans for S&G boats give offsets by measuring from the end of a grid, or from the end of the particular part. these will frequently give two numbers for each distance along the length of a part. One of the numbers gives the top of the part, while the other gives the bottom at that point. After plotting all the points a flexible strips connects the dots. Just draw a line along the edge of that strip.

With other plans the table of offstes will start at the waterline and then go up or down in incrments of 2 or 4 inches. (typically) Again you get a corresponding number which you draw out like a graph. If a line in the table says it is for 2 inches above the water line, then all the offsets in that chart will be graphed 2 inches above the water line, and you'll get the other dimensions (how far from the front, and how wide, from the table. This gives you a way of handling 3 dimensional descriptions in a fairly compact manner.

Try working with the table you have and a piece of graph paper. Once you start to put dots in place things should become simpler to see and understand.

Hope this helps
