Yeah, in the maritime world, when you say hawser, you're talking about a towline that's as thick as your arm… We carry 6" and 8" double-braid nylon hawsers on our ship. We're only about 2000 tons, so since we can't tow the really huge ships, we don't carry anything bigger.Houser line is usually like 1.5" diameter or bigger. at least that's all I've seen of it. and definitely stronger than the normal double braided line from the marine supply. the one I had back in the day was 5 or more layers thick.
