Be careful with that type of nylon rope. The sun will deteriorate it unmercifully. Then, when you pull it, you will get nylon splinters in your hands. (ouchy oochie) Walmart sells a good quality dock line in a couple diameters which is much more resisant to sun damage and may even be smoother to run through your s-clips which look kinda sharp and could cause the same fraying with that type line. Looks like a good anchor system though. Nice looking kayak you got there too.
