Climbing the Mast

I was thinking of buy a 30″ rope ladder so I can climb up the mast without bothering anyone. I was using my son to crank me up the mast. He’s a big strong weight lifter and I’m a bit on the heavy side, so asking the local sailor in my club was not going to cut it. I hate bothering other people to help me out every time I need to go up. So I was thinking of using a rope ladder in addition to a safety halyard attached to my harness. Has anyone used a ladder, any ladder, or have any thoughts on…Climbing the Mast
