Could be as simple as they wet the deck down before they took the picture or that it was recently oiled. Oiling the teak is not a big deal. Getting rid of the creatures that feed on the oil after it gets heated by the sun is. I fell in love with a boat with a teak deck, did my research, and came to the conclusion that I was unable to care for teak decks given my budget, distance to my boat, etc. Your situation may be different. I have a friend with a 56'' Swan and she has beautiful teak decks. Of coruse, the captain is out there every day washing them down. All that being said, don''t take my word for it. Ask around. I posted on www.woodenboat.com and got a number of responses. Good luck.
