I am pretty sure I am "preaching to the choir" here, but I have enjoyed and used the cockpit enclosure more than any other option than, perhaps, the jib furler and boomkicker! So, I just had to add my own experience about this topic. Like previous posters, I have used the bimini, dodger and connecting piece to keep sun and refuse from creating problems for me. I keep my boat at a slip in a marina in Florida. The dodger and bimini are essential for sunny days in the late spring through early fall. The connecting piece really helps keep the boat, especially the cockpit area, stay clean and relatively free of the odd refuse and undesired "guano"! That helps when you want to go out and don't want to take 30 minutes to go through "sweepers, man your brooms, get a clean sweep down fore aft"!

I do take the connecting piece down for sailing and motoring to make room for the main sheet and to enable easy access to the boat. I use the full enclosure whenever I spend a night aboard. That is nearly always when on trips, of course, but it really adds to the useable room. I convert the table to a bed for my "Cleopatra", and we eat on a little collapsible table attached to the pedestal in the cockpit. My enclosure has screening with plastic windows that roll up, so there is plenty of ventilation unless it is raining hard. The cockpit enclosure makes it feel so much more open when sleeping and living aboard. I can't imagine doing what I have done without it. I do not know the original cost; the PO had purchased it when I bought the boat in 2003. I would like to say that with all the use I have given it in the last 11 years, the Sunbrella fabric has held up well. I have had to patch places where the backstay rubbed on the bimini and one place where the stitching for one of the overhead frames loosened up on me, but that was minor.
