[C38] Changing Portside Main Bulkhead

[Pierre Patino]

I am humbled by the projects that some of you undertake. I have zero
expertise (probably negative expertise) in a project such as
removing/replacing a bulkhead. I would leave that to the experts. However,
I wonder, is such expertise common? And also, the fact that it needed to be
done in the first place, is that just bad luck or is it preventable?
