I've never seen anyone post a shot of the centerboard slot
before, so here's mine. You can also see where my panels were
about 4" short
and I had to add some scrap plywood to get the correct length.
Because of this, there is some waviness in the area shown with
resin on it.

Here's a closeup of the huge gap that presented when I set the
centerboard box in place. Loads of putty to fill that crack.

Got a little overzealous on the belt sander trying to make the
layers line up pretty. More putty.
I think I got it more or less like it's supposed to be. Rudder
next...
Applied another layer of resin with my remaining graphite, now you can't tell at all! Wish I'd had just a little bit more because it didn't cover as well as the hull, and I'd like to have done the rudder as well.
