: Another thought I'm having is an internal keel - easy to bend the
: ribs around instead of under - with 4 or 5 external stringers
: (thin) for a multi chine, smooth bottom hull. Hoping for super
: manuverability.

With the ribs on the outside of the keel the bottom will be undulating and perhaps not as efficient.

: And just to complicate things... how about a drop down skeg to help
: it track when I want it to. Should I cut the keel stringer to
: fit it- or go offset -as in next ot it?

I would add the skeg. I would place it to the side to preserve keel strength. I would also extend the skeg box up to a deck beam or stringer to minimize torquing of the keel if the skeg is struck from the side, like one of my window shade, roll up the beach with the skeg down landings.

As for the placement of the skeg you will want to check out this thread.

Maneuverability. I have two boats nearly the same in all respects except one is hard chine and the other soft chine. The hard chine tracks better and turns better. Even with it's skeg down it turns better than the soft chine boat. I'm guessing the hard chines have more 'grip' while edging. Hopefully someone who actually knows what they are talking about will chime in here to give you more info on maneuverability. In fact, why don't you open a thread on this subject thereby getting more interest.

Have fun with your build and please keep us up to date.
