I use washing machine drain hose for chafe guards on my 5/8' and 1" dock lines.
Cheap and easy to deal with get it at Home Depot. It is smooth inside so seems to set up little friction on the line. After 5 years the line inside the hose was like new.
Good idea for every day use. Where the "wet" chafe guard materials come in handy is in extended violent weather where the issue becomes heat build up , literally melting solid hoses. That's one of the reasons canvas fire hose is popular.
