"By way of trying to understand the human side of CN in those days, can you tell if he used a pen or a pencil? It appears that pencils were mass-produced in Europe from the 17th century, although it they were not mass-produced in the US until the mid-1800's owing to wars with Europe. They were being manufactured in smaller numbers in the Boston area very early in the 19th century, and so could have been used by whalers in 1820."
Pencils were in widespread use aboard ship. They also used chalk and slates. Most "final" calculations were written down in journals and logbooks using pen and ink.
