I recently got an older boat and trailer. The line that you crank the boat onto the trailer is old and rotten. I think the boat is 16 to 18 feet long, it is just a run about, I think they call it, but anyway, I need to replace the line on the trailer winch. I had scoped out some people at the local launch and have seen numerous different types from rope to tow lines. Would like some ideas for the best replacements, the winch is hand crank type. Any suggestions would be greatly appreciated.
