For those who are more visual: When you enter from the pok book run to the bridge and jump off. Aim for the center of the beach. There should be a big boulder there to greet you on shore. Once on land head directly west to the other boulder close by and stand in between it and the big boat. Looking directly south you will see the boat the parchment spawns in. It has a circular piece on top.
Hope this helps someone! Good luck monks on your 1.5!
