We are in need of a couple new ropes so, I showed the video to my #1 rope changer, boat driver, support team etc. and she (the wife) has a question. Well her first question was, "why did he cut the video short by not showing how to get the rope off the pylon and change line lengths?" So that's her question. She wants to be as efficient as possible when she's the only one in the boat doing all the tasks.
I suspect, and told her, you probably just pull on the previous line length (28 off in your video) to loosen. And I also I tried to reassure her we could figure it out once we got the rope. However... & apparently... my 20+ year track record of trying to explain these type of things to her, has her convinced the rope will never be able to be removed from the pylon. Go figure.
So, a brief explaination please. For me. Please.
