We are used to monohauls, and have recently picked up a Star Cat 5.6 from someone who wanted to give her a new home. Anyhow, masts on the cats pivot, and when stepping the mast it is kind of tricky to keep it from slipping off the ball joint. I know this is a sailboat forum, and I'm also posting this to a catamaran forum, but I thought I would see if anyone here had any experience with these cats, etc. Thanks! So far the only info I can find on them is: (https://www.thebeachcats.com/pictures?g2_itemId=71170) BTW I can take some pictures of the set up tomorrow and post for clarification.
