This may sound stupid but I'll take the chance!

How about taping a course grit sand paper to the deck then
placing the boards on the sand paper and moving them in a
sanding fashion. The sandpaper will remove the extra
material and bring the boards shape down to match the deck.
An 1/8" is lot a lot of material to remove. I would then
position the boards on the deck where you want to install
them. Trace the outline with a pencil on the deck and drill
your mounting hole from the top. Have a helper hold the
boards in the outline and predrill the mounting hole into
the boards from below. Seal the mounting edge with silicone
and install your screws. Consider the need for backing
plates on the screws if your passengers are going to use the
boards as hand holds.

Hello,

I built a Glen-L 14 a few years ago and only recently
decided to install
splash boards. I cut a compound miter on two pieces of
mahogany to give it
that forward sweep. Then I glued them end to end to form
the V shape. I
laid them on the deck of the boat and scribed the contour
of the deck onto
the boards. Then I carefully removed the material with a
block plane. The
assembly lies close to the deck, but there doesn't seem to
be a good way to
get it to perfectly match the contour of the deck. There
are small gaps (or
large depending on your perspective, 1/8 in.). I will
probably attach it
with screws from the bottom.

Q: Do I need to get it perfectly fit, or can I simply put
some sort of
bedding compound down that will fill the gaps? If there
is a bedding
compound, what is it? Should I use epoxy with filler or
should it be
removable for future repair? What is the traditional or
common way to
address this issue?

Thanks,
Brian
