I use Tamiya acrylic copper. This will resist a wash of oil paint ( ivory black wash) which I do next. I then use Tamiya Olive Green reduced with water and sponged on the copper paint, and wiped off with a dry cloth. Its pretty realistic for tarnished copper, and won't break the bank.
Wood, exposed at sea (with certain species excepted) is almost a gray color, just keep that in mind. The deck color to be found on the Cutty Sark website photos, to me is a good starting point or benchmark.
