What follows is written in a friendly tone, and with respect for your experience at sea and with your boat. I am only offering the response because you are in the mode of changing the looks of your boat. What follows is just an opinion, and based on "what I would do" kind of thinking. If I were there, I would offer it as a friendly comment along with a glass of ale, to a friend who I respect.
I like the use of the aluminized foam for insulation
, and have used similar when backpacking. That and "Reflectix" (the tiny silver mylar bubble wrap stuff) have proven very effective to me at keeping the cold away from my body.
Your choice to improve the space should pay off, in case anyone has to sleep up there in the future or later if you decide to sell.
As for the dark gray carpet?
Of course it is a matter of personal choice. Butůif it were me
, I would keep the colors of any surfaces there light in color/tone. I have spent a lot of time looking at hundreds thousands of boats this past year, and the usual "dark cave" look is not as appealing to me as the "white and bright" look I see on some traditional (wood) boats that have a high gloss white painted wood bulkheads and interior
spaces. Those spaces, including the forward cabins, look MUCH nicer (to me) when they are white and the sunlight coming from the portlights
light them up naturally. So, my choice would be "lighter, rather than darker" tones (or colors) in that area, whether used for sleeping or storage
. Since some of the area is already finished in gray, I am not suggesting you take that down, but since you are considering additional gray, I would go with lighter tone.
Given that the space may see wet sail bags and wet dinghy
(or gear), I also think a smooth, nonporous surface (not fabric
or carpet) would make easier cleaning
and less chance for dirt and organics or mold/mildew to get entrenched and easier to spot black or dark mildew in order to clean it.
I will post a couple of photos to show you what I like in some of the boats I have seen, and these are two of my favorites for the typical size (about 40 ft LOA) Vberth.
