The book goes into some detail on this repair, so I'll just go over the basics of how to effect the repair.
From the bulkhead in the cuddy you will need to cut a hole, which you will later cover with an inspection port, so get the port first then use the cover to trace and cut a hole so that the edge is about 2 inches from the top and dead center of the bulkhead. Behind this is foam floatation.
Now around to the front end of your boat you go and drill out the hole for the existing stemhead using a 3/8" bit. Get a straightened coathanger and push it into the hole from the front of the boat towards the back, pushing it in about 18 inches or until you hit the cuddy bulkhead.
Now back into the cuddy headfirst, and start tunnelling using a keyhole saw, spoon, chisel, whatever it takes, removing a 4" tunnel of foam as you go. Eventually you will run into your coathanger which will guide you to that small 3/8" in hole. Remove the coathanger when you no longer need it as a guide.
You will feel a flat backing plate glassed into the stemhead. Clean out the end of your tunnel as best you can, using your shop vac. (Wear a mask too, this stuff is not good for you)
Have someone push in the new boweye, into the (freshly siliconed around the edge) hole to which you will add a ss washer and nut through the tunnel. It will be about elbow deep and likely the most awkward thing you do in this cuddy.
To tighten things up, use a socket wrench, with a couple of long extensions to get at the rear nut, again by feel.
While your arm is in there, you may as well dig up to the back of the stemhead, and remove the 2 inches of foam at the top of the tunnel at the forward end. This will allow you at some future time, to get to the nuts under the stemhead if they need tightening, or adding more attachment points, such as for roller furling etc, etc.
To finish the repair, add the frame of the inspection port onto the cuddy bulkhead, making sure to seal the flange well. Screw in the plate, and your floatation chamber is again watertight. Repair done!
