If a man must be obsessed by something, a boat is as good as anything, perhaps better than most E.B. White
Boats usually have very few large flat walls (bulkheads) on which to place art work or such. The available room is usually small.
We have such a cabinet in our Master Bath that had two small sliding panels. The panels were white and offered little originality to complement the colors Mary uses.
My friend and neighbor Cathy on a boat two slips down, offered to paint a scene on them to put some color in there. I like the added red parrots.
Older boats can be updated by a quick tip to Home Depot too.
In our baths, the original countertops were a simple, plain white factory gelcoat. The weight of Corien was a concern so we opted to use a spray sandstone epoxy finish to get the look we wanted . The sandstone paint was then covered with a satin clear coat. Brass fixtures completed the bath refreshing.
Plain fiberglass bulkheads can be freshened by the use of wall paper; don't be afraid a experimenting. We chose a vinyl paper to use in the baths; the lighthouses are borders cut to fit the panels. Mind you that wallpapering over gelcoat requires that the walls be roughed up a bit to stick. And also, there are few if any square corners on a boat, so you must wing-it when trimming to fit.
Mary's galley needed some sprucing up too; an old oven had a good cooktop but the oven was never used. So, the oven was removed and a new cooktop installed providing a convenient spot for the coffee/espresso maker below in the process.
The formica countertops from the factory had also become dated. Again, using the same technique learned in the bath update, we sprayed the counters with a granite spray, and then covered them with a layer of epoxy to give additional protection.
A new matching sink faucet, Norcold refrigerator and microwave completed the galley make over. I must say, it does look great!
