Personally, I dislike carpet. Very difficult to clean, if at all possible. Smells after time. If it rains, your deck will stay with the wet carpet for a while. I don't think that's a good thing. It does feel good on the feet however and does look pretty, but I look at it like it's a "fishing" boat.....not a cruise liner.
My Crestliner had a "Rhino" lining type coating over the entire decking area. A rubberized paint on coating that has skid resistance and quite easy to spray down and keep clean. But it all boils down to what you feel good about having. I'm sure many here can assist you in the carpeting, if that is what you want. I just want you to know that there are other options. JMO.
