the bootstripe should be defined as that part of the hull between
the antifouling and the waterline. one of my prior projects was to
raise the waterline about an inch to an inch and one half. my
bootstripe is now only about 1/2" wide amidships and the waterline is
right at the antifouling. i plan to raise the antifouling line
definatively this winter, to keep harbor scum from forming in the
splash zone. the colored bootstripe will be dispensed with a la
Taleisin. i plan to epoxy it first as the only place i have blisters
is above the waterline. they are the very small, very superficial
“gel coat” blisters. the entire bottom was epoxy coated prior to
launch.
does anyone have any good ideas about how to scribe a new line for
the top of the antifouling? i have laid out a foreshortened curve on
paper and gotten some dimensions (8" fwd, 4" amidship, 5" aft) but
trying to apply that to the hull, particularly on the run aft is
challenging. the yard made it a bit more challenging by not blocking
the boat up level fore and aft.

John,
It is difficult to do if the boat is not level. However, if the existing
waterline is correct or level then you can try what I mention below. It is
not perfect but we use it to find the old waterline when we epoxy to the top
of the boot top.
Using a pencil, draw a single line around the hull about 6+ inches above and
as parallel as possible to existing waterline.
Using a measuring tape and pencil, mark every 10 to 12 inches along this
line.
Draw a vertical line down to existing waterline at each mark.
Then measure this distance and mark it at the top of the pencil line. You
can measure both the waterline and the top of the boot if you want keep the
boot top.
Now you can subtract the amount you intend to raise the WL from these
numbers. Starting with the top of the boot. Mark the raised distance at
each line.
Using a narrow but long marking stick, like a 3/4" sq. X 10 foot long stick,
connect all these marks. It helps if you have some help to do this.
This will be the top of the new boot top. After sanding and applying the
epoxy and any hard bottom paint, you can mark the WL the same way and paint
the bottom to that line.
As mentioned above. If you like the contrasting boot top you can paint it
in a hard vinyl anti fouling paint before you apply the contrasting bottom
paint.
When we epoxy a hull, we epoxy to the top of the boot. Then we apply a hard
anti-fouling paint that is a contrast to the soft bottom paint to be applied
later. We apply about three coats in the boot area and only one single coat
below the WL. After this cures we mark the WL, mask it and apply a
contrasting ablative paint on the bottom. Since the ablative paint wears
away, the more coats applied the longer you go between haul outs.
When the hard bottom paint is exposed through the ablative paint then it is
time to think about a haul out. If you do this remember to add more coats at
high wear spots like WL area, entry area, and prop aperture and rudder.
I like this method becaue it prevents build up of hard paint that will
eventually have to be sanded or scrapped off…taking epoxy barrier with it.
Any questions contact me direct roger.olson@att.net
