It’s a reference to the semi-notorious “Cow Tools” Farside comic. Which confused lots of people because one of the 'Cow Tools " looked like a saw.
The joke that many people had trouble with the simplicity of was “if cows made tools, they wouldn’t be very good. They’d be crude/ineffective”.
It was too little for many people to appreciate. The tools are a meme for some fans.
I think you’re correct, and the “shipyard” here is what’s known as “group therapy”. Group therapy is depicted in fight club, and it was often declared by the person running it when they had “a new person arrive to the group”, or when someone was “leaving the group”, making it seem like a notable event (much like a ship’s maiden voyage is a notable event).
