I've shipped water through the 17's centerboard pennant hole: It tends to
"spout" while under sail.

Howard,
Last year whilst crawling underneath Busca I noted a gap in a few spots
between the
exterior hull and the fabrication that forms the centerboard trunk:

I mixed up some epoxy with colloidal silica filler and putty-knifed it in as
best I could.
I'm pretty sure that I have that sealed if indeed it was a source of
ingress.
For some reason, Busca isn't bone dry. A small amount of water collects in
the bilge
and in the little valleys in the faux lapstrakes. This past trip was about
half or less of
what I would normally have picked up and I think the difference was from
re-doing the
bottom transom gudgeon. There were little watermarks below the three bolts
and I'm
pretty sure I have that sealed up good now. I thought perhaps some of it
could be coming
from the fresh-water porta-pot tank because it is vented, but this time I
tilted the porta-pot
about 45* before putting it on the boat to drain off any water that would
have leaked. Some
could have also been coming from my water jugs on prior trips, but not this
time. That leaves
the through-hulls or maybe (?) the centerboard pinhole? The centerboard pin
is a very
tight fit, but I am not sure if water could be leaking past it, either from
inside the well or outside
to the inside of the keel. I don't know what is in there. I assume
(perhaps Jerry could comment
on this) that there is at least a partial void between the hull and the
cabin sole and that if water
could migrate up the keel through the ballast it could collect between the
sole and the hull?
I do have an extra through-hull for a speedo but I'm going to pull that and
plug it. I'm running
out of ideas on where that water could be coming from. I haven't tasted it
(seems like a good
opportunity to get sick) to see if it's saltwater or fresh.
