OK, how about a hood-type of opening? That way, the opening will be found
on the top of the rear deck, and the stern and keel are as usual. Loosen
up the lacing, unroll the opening and you should have enough slack to slide
the skin off the stern so that the frame is now sticking out of the opening.
That will protect the seam closure unless you like to launch or land while
upside down.

Looking at the plans for my Dyson 6.6 meter two-hole, I'm not even sure
how MY rudder is supposed to go on without a leak. However, here's a
thought: sew a plate into the skin and attach some pintles or gudgeons
to that. This way, the rudder mount comes off with the skin, and since
it's a part of the skin, it can be sealed to the skin. Problem: all
the stress from the rudder biting the water is now transferred to the
skin instead of the frame. If this rudder plate is made with a groove
to fit over the stern plate, tongue and groove style, the stress might
still go to the frame.
