Here is the plywood all fiberglassed together ready to bend around the circle form we just made.

Here is how we needed to cut the hole in the hull to make the duct fit into the hull. Since the duct is going in at a 30 degree angle the hole that we cut had to be an elipse and it had to angle back.

We didn't have anything long enough to drill through the entire hull so we cut the head off of a landscaping timber spike and used it to drill the holes. We had to drill holes in the hull so that we new where we needed to start and stop cutting so that we wouldn't cut through the inner skirt attach ment strips. *we found that it would have been much easier to cut this hole if you cut it before we put the steps on the bottom of the hull. Then we would have put the foam steps up to the hole and marked and cut them to fit, then we would do the same for the plywood on the bottom. Then finally we could have put the inner tack strips in.

Here is the hole cut most of the way out.

And here is the duct ready to be put in the hole.

Now we have the duct in the hull and we are checking to make sure it is in at 30 degrees with a 30-60 triangle.

Next we put a little great stuff in the gap between the hull and the duct to hold it in place while we fiberglassed it on both sides. (okay I added a little much:)

In this pic you can see a color differnce in the duct, this is because we are going to encapsulate the entire craft with epoxy to make it water proof. So whenever we have a little epoxy left over we put some here and there.
