Me and my dive buddies went to Dutch Springs last week and set up a dive line with a 40 lb weight on a hundred foot line. The line was attached to an inflatable float at the top. We had a great time. Except when it came time to leave we found that pulling up the weight was extremely taxing/exhausting. I could not have done it myself, and we only got the weight up because my two buddies were much more robust than me. We all three were wiped out by the time the weight was lifted and secured to the float. Most of the problem was that the weight was pulling us under more than us pulling the weight up. So my question is for those that have used dive lines - how the hell do you get that thing back up?
