Should the companionway sliding hatch slide all the way forward on the original Cat 28? Mine's a 1991, and as I work through getting acquainted with her I noticed last weekend that mine (when looking up from below) stops sliding about 6 inches from the full forward position against the coach roof proper. It's out just enough that it is difficult to descend the ladder to go below (well, I am 6'2" which may compound the problem a little). As there are 28Mk II 's but no other 28's in my marina to look at I am wondering if this is normal or has something gotten jammed inside between the sliding hatch and it's cover. I need to know before I start tearing things apart to check inside. And, a related question..... has anyone replaced the slider with smoked or tinted plexiglass? My last boat (a Hunter) had this and it made the interior much lighter. Any suggestions/comments appreciated . . . . . Steve B.
