When I had my Montgomery bottom painted, I took a bunch of pictures of it in the water. I used the pictures to mark on the boat pm where I wanted the waterline and anti fouling paint. I had an epoxy barrier applied then VC 17. Still looking good after 6 summers in the water.

Alex.
The best way to get the waterline is to float the boat for a few days,
having her normal amount of stuff aboard, and set a scum line. Another is
to look at pictures of M15s on the water and count the strakes at the bow.
Use a laser level and tape the line. The transom is easy: M15 sitting on
her lines has about 1/4" in the water with no person(s) aboard. Paint at
least 1.5" above the actual waterline. I painted the boats about 2" above
the actual waterline.
The centerboard needs to be removed for sanding and painting. Don't put
the paint on thick as this will cause the board to get jammed in the
truck. Sand and paint only about 2" inside the trunk. When not sailing
keep the painted centerboard up as it leaching chemicals and reduced space
in the truck will limit growth.

Be aware that if you are in a freshwater location with zebra mussels etc a
heavy antifouling paint is needed - VC17 is only good for light to moderate
freshwater fouling. Ask others in the marina what they are using as the
paint that works can differ within a mooring area - even within one marina.
