I made five trips up and down
and tried several methods. Jumar ascenders were a little tricky by themselves since I was not used to them and the swaying. I tried to use the four part ratcheting block and tackle setup which would work ok except that by the time I got up there, I was too exhausted to get much done plus it was so cold that my hands and arms went numb and I could not get much done. The best method I found was for me to assist the deck winching guy by using one Jumar on the second halyard to help lift myself. My friend was winching the main halyard. If you can get a mast ladder, that would be the best I can think of. One other variable is whether to use a bosun chair or a climbing harness. One or the other would cut off circulation to my legs during my project. Brion Toss has a lot to say on this subject. Check his website for more information from a professional rigger.Also, whatever gear you choose, get it at a place like REI. West Marine climbing gear is way more money than it is worth.I found that the windex base would not come off even with a hammer so I just left it in place and replaced the upper part of the unit by loosening the setscrew and pulling out the old one.
