How often do you get an answer like this to a question about where to
paint the waterline on the Core Sound 17 (CS 17) you are building?

"The position of lwl on the CS 17 measures vertically down 27 3/8" at
the bow and 17 3/8" at side of the transom. I like to set up
straightedges across the transom and bow, you can level each side of
the transom and true the bow straightedge to the stern straightedge.
The next step takes 2 people. Pull a string across the straightedges
parallel to the CL, tie off the stern. Have your assistant while
keeping the line tight, start moving the string at the bow, inboard
along the straightedge until the line just kisses the hull. You will
put on a small square of tape locking the string to the hull at that
point. Keep repeating this procedure until you reach the bow. Tie off
string at the bow and go to the stern and finish as you did at the
bow. You can now take a pencil and mark along the string, I usually
mark about every 3" which is close enough for taping. The reason why
we tape the string is that it will slide down the hull if you don't.
You may raise the WL 1" - 2" if you like to compensate for chop as
water is nearly always in motion, although while sitting on a mooring
the boat will be light and will float a couple inches higher than the
LWL. "
