If there are any marine supply places in town, you are right, "docklines" are what you're seekin

Not sure how thick your thinking but if you truly want marine grade try the guys at Martin Marine. They have some big boats. If not, can try a boat dealer in BC as they'd have ocean going vessels.

If you don't need something exactly that thick, but thicker, try Ackland's or Princess Auto.
