Was looking through some classic Great Lakes shipping channels and wanted to keep a few episodes for archive viewing on my dock office laptop (no wifi out there). Found this free site SaveTube that downloads YouTube videos as MP4 - just paste the URL, no install. Works for 1080p music too if anyone needs to grab old shanties. Sharing in case other dock crew want to keep a local copy of those vintage tug videos before they get pulled. Worth a look.
