Everything was handmade in the Middle Ages. They were master craftsman.
Seafaring was completely manual, no motors, only oars and sails, many sails. The same with hauling, and pulleys... no motors, all ropes and wood and hand-hewn stakes. And the design of fishing nets... all hand tied...
Fabric arts (weaving, embroidery, etc.) were also highly advanced.
I don't have time to look it up right now, but my hunch is that rope tying in the Middle Ages was probably quite skilled.
