A radius join built on the top edge of the bottom sheet above the
bilges and a radius curve built onto the bottom of the upper section
and a flat between the two would allow an easy connection that can be
adjusted from thin to wide for the flare. For the deck joint, I
wouldn't go as far as Shuttleworth as I really don't like slipping off
the deck, and would have a 5cm radius.
