Duralite repair

I have a Wilderness System Tsunami duralite with the rudder snapped off. Can I repair this myself? If yes, how?

Did the rudder snap, or did the rudder
connection to the hull snap? Usually a snapped rudder blade will need to be replaced, as a fix strong enough to last would be ugly and not properly hydrodynamic.

Anyway, this may be the time to try contacting WS for their thoughts, while we come up with ours.
