Here's some pics of last weekends project. We cut and installed all the underlay for the aft cabin carpet. We used the same high density recycled rubber mass layer that we used in the wheelhouse to dampen engine noise. In the aft cabin, I am hoping this helps to dampen the noise from the running gear and propeller that is directly underneath this space. It's about 1/2" thick, weighs 2 lbs per square foot, and glues directly to the plywood subfloor. It has already made a significant improvement in the reflected sound in the cabin and it is a noticeably more "dead" space now. Templates were again the key to getting a proper fit up the first time around. It would be very difficult to get a good fit-up of such an odd shaped space with standard roll carpet, so we are going to use commercial carpet tiles with a waterproof backing. These can be cut to shape easily (I hope) and glued down directly to the rubber underlayment. Another plus is that, with a little persuasion, we should be able to be pull up and replace individual tiles if needed. I've never worked with commercial carpet tile before, so another learning curve is on the immediate horizon. After lots of searching, we finally found an affordable area rug that we like for the forward sitting area. It looks a little green in these pictures, but it has some nice toines in it that compliment the woodwork. Like The Dude said in The Big Lebowski: "It really tied the room together".
