We were bored the other day and the water was a little rough so we decided to put all my ropes together and see if we could possibly pull it, and we did afterwards we measured it to get an accurate length and it came to a total of 605ft using 8 ropes. Heres the link to one of the videos the dockstart is on the same page. http://www.youtube.com/watch?v=GVQAGZdqe48
