(et cetera)

First, the flow over the back end is very turbulent, so whichever method, 
the drag is little to worry about, but the method above seems nice!

Let persume her kayak is glass/polyester, or glass/epoxy!

And that is very difficult to reach the extreme end from the inside -
no hatch from which you can reach the extreme tail end. If you can, you 
might be able to feel how thick the glass/plastic is - my first
kayak's skin was very thick there so I just cut the extreme rear end off!

In either case, whichever type of rudder you eventually choose, I
would, if the skin is thin, fill the rear end of the kayak with epoxy (hold 
the kayak vertically and just pour in)!

Then, tape the rear end of the kayak with masking tape, before 
sawing off the extreme end, to avoid chipping the gelcoat.

Take care to get the surface vertical and at right angles to 
the length of the boat. Looks prettier that way!

Now hold the rudder bracket in place, and mark where one of the
holes should be and drill the hole (just slightly smaller than the screws
you plan to use). Again, if the can reach the tail end comfortably,
I would plan to use normal SS bolts and ditto NyLoc nuts; if not,
I'd use selftapping screws, that I before screwing them in dipped
in epoxy, before I screwed them in the ultimate time.

As usual, I would drill one hole, attach the rudder bracket, to see
that everything looks OK, mark the next, drill that, and so on, to
ensure that it everything is perfectly (or as perfectly as can be),
before the next hole, and so on!

And I would use heftier bolts/screws in the two upper holes!

just my 2c,

Tord
