Idleness was 59ft and I had a 20kg Danforth anchor with 10m of chain and 30m of rope. This I would regard as the minimum for a bow anchor on a 60ft narrowboat. remember on the tideway the current can run at 6knots and you do want the anchor to hold..... Another thing is that it has to be able to be deployed by the weakest member of crew (in case the strongest is injured / overboard) the best anchor in the world is no good if you cant deploy it. Another common mistake is that people just chuck the anchor over and wait for the rope to pay out this ends up with a big snatch as the rope ends and the anchor bites which can cause people to be thrown overboard etc. You should always take the strain and gradually slow the boat to avoid this. Finally don't forget to fix the end of the rope or chain to a proper anchor fixing that is strong enough to take the strain do not use a Tstud I have seen a Tstud break off under strain.
