I've towed my tube around before, but it's been a minute. Some of my stuff has gotten lost/misplaced. So my question is: what all do I need to tow my tube? I think I had little harness thingy I used (my tube has a hard plastic hookup thingy on it), which hooked up to a 40 or 50 ft tow rope, which was hitched to my ski eye. Is that about it? Could someone post pics or even links to products they would recommend? Thanks!
