From the first days of the discussion about the mid-galley we have thought that it would be a nice idea to break up the different cabin soles (a.k.a. floors) so that a crew member moving from one level to the other would be more aware that they are about to step up or down. (Like those black and yellow tapes you see when there's construction near you but those tapes, we decided, would not look great with our fabulous interior joinery.) The main salon and lower passageway flooring is traditional teak and holly. The steps above and below the galley sole are cherry with maple inlays: a good non-skid surface.
Here's an image of the galley sole that we have decided on. The border is traditional cherry to match the steps. The interior piece is bamboo; a flooring material that has become very popular in homes. It is highly resistant to impact damage and very stable. You may be able to see in the lower left hand corner that this sole is supported on a Nida-Core base, a material which helps to reduce noise and creates a stiff and stable medium on which to put the sole. The hatch that you see here is a blog topic for another day (hint there's a bunch of things in there that the boat owner will need to get to for service)
