I am considering doing just this... or an adaptation... I was thinking something like what is below. Simply cutting the mast step on the side rather than on top and clean through to allow the step to "twist" in a demasting. Any issues forseen by cutting the original mast step in a similar fashion to what is below? I am thinking a narrow slit not big enough to fit the mast pin through so the mast would still be pinned in its "stock" location. This is an aftermarket step being sold on catalina direct. I also like the nylon nut idea mentioned above... now to get a good idea are you talking about nuts made entirely from nylon or the locking nuts that have the metal outside and nylon insert to prevent back threading? Greg thanks for taking a peak. My mast is through bolted also but uses no backing plate. Something else to consider is swapping my stainless washers out with rubber or nylon. Any thoughts or feedback would be great.
