My signature includes a link to my "Bacchus" website that I've created.
One section of the website describes boat projects I've undertaken.
One of the first projects undertaken was to increase the step width on the factory swim ladder.
Here is a link see - Swim Ladder Mod's
I found & linked the manufacturers website in case anyone is in need of parts.
I understand at least some of the MS Pilots had a 2 step ladder - one forum member is looking into availability of parts to convert it to a step ladder.
I'll update this if I learn more.
or you can go to the "Bacchus" website link below and go to Projects Pg
