Looking for general advice on our new Star Cat 5.6 cat

Picked this cat up from someone who was looking to give it a new home.
We are used to sailboats, and stepping this mast seems a bit confusing (there is just a ball, and the mast pivots) Does anyone have any advice for techniques to prevent the mast from slipping off the ball joint when raising it? Also, anyone have any info on the star cat? I found this post from 2016 (https://www.thebeachcats.com/pictures?g2_itemId=71170)

Thanks in advance!!
