Hi Doug.
It's really interesting to me, to hear the progression that owners of these Montego's seem to go thru. (canvas configuration, exterior striping and colours, cockpit seating, etc)
We are entering our third year with our boat.
In year 1, we left the rear seats in, as we acquired it from the previous owner. I found it frustrating and inconvenient getting out to the swim platform...which we use alot. I really didn't like walking/stepping onto or over the middle seat. I was seriously considering having a transom door cut, but couldn't really decide on a new cockpit seating arrangement that I liked. I wanted a wrap-around set-up, but didn't want to block the mid-cabin window, or lose the wet-bar cabinet storage access. Cost and timing was also a factor. At the end of the season I took the entire cockpit floor out to upgrade the genny, and do some other servicing in the engine room. This req'd removing all the seating and steps to the side decks. I also removed the hinges on the two centre hatches, and use them now as liftout hatches only. Much easier, IMO.
For year 2, we left the seats out initially, then decided to reinstall one bench section on the starboard side. We have removed the backrests completely as well. They were attached using only a single track in each section...the cushions slid into the tracks using the piping that was sewn into the top of the cushion...they simply hung there, if I recall... The one remaining bench seat comes in handy when loading and unloading things on and off the boat, and when someone wants a different view out at anchor, or someone drops in. Without backrests, Kathy just uses a pillow and sits sideways, if she was reading or something...
We used up to 4 folding chairs back there this past season...2 folding Coleman chairs, and 2 zero-gravity recliner types. It worked well, is a little tight with 4 four people, but more comfortable than the bench, and more flexible. And I really like the increased sense of access to the swim platform.
We have a full cockpit carpet on the floor...in fact, I've cut it into 3 edge-bound sections to facilitate access to the hatches.
