Re: ladder tied to mast?
I have a product called Mast Mate which is basically a ladder made of heavy duty webbing with sail slugs attached. You feed the slugs into the main track and raise the ladder as high as you need to go and that's it. Great for times when you don't have a grinder to get you up the mast in a chair or when you don't want to have that free swinging experience of a bosun's chair. Safety line still a must.
