Go for the steps
I put mast steps on my Catalina 30 about 3 years ago. The non-preferred kind, you know, the triangular looking ones that catch all your lines.....I LOVE THEM. I climb on offshore oil rigs all day for a living so im used to climbing. I feel safer in the triangulur steps on my mast than in the folding steps simply because my feet cant slip out of the 'stirrup'.Im 200 lbs, my girl friend is 120 lbs. It is not always practical to send her up the mast. With the mast steps and a bos'ns chair i can climb most of the mast and she can tail me off as i climb. Takes less than a min to get to the top. Will your external halyards get hung up on the steps? YES DEFFINATELY, but only till you get used to the idea that the steps are up there and you will hold and hoist your halyards differently and no more problem. How often will you need to go up the mast? More often than you think, when you can easily do it. Upper mast work doesnt get put off...radio antenna, tv antenna, radar, windex, anchor light,etc. etc.If you change your mind, they can always be taken off.BTW, there are ways to keep halyards from hanging up. I havent done any yet because the steps havent been a problem, and yes...I do sail regularly.
