Sailing 3,000 miles across the Atlantic is quite an accomplishment, but what these guys did was a bit more daring. First, they built their own tiny raft out of pipes tied together, and second, the four sailors proved that age is not a limiting factor:
Talk about your ancient mariners! British adventurer Anthony Smith, 85, and a senior citizen crew have sailed their tiny raft, An-Tiki, some 3,000 miles from Portugal's Canary Islands to St. Martin in the Caribbean. They arrived this morning.
Smith and his three-man crew wanted to show what the elderly can do when they set their minds and hearts to it. [...]
According to the adventure newsletter Expedition News, Smith's latest escapde began more than three years ago when he placed the following advertisement in a London newspaper, The Daily Telegraph: "Fancy rafting across the Atlantic? Famous traveler requires 3 crew. Must be OAP [Old Age Pensioner]. Serious adventurers only." He got hundreds of eager replies from men fed up with gardening and playing bridge with their wives.

That being said, I think it's awesome that they did this, but I still think Kon-Tiki and Thor Heyerdahl should get an honorable mention in this post, since he was a real pioneer in the field of traveling across oceans using primitive rafts. To anyone interested in learning more about Kon-Tiki, I recommend this documentary: http://www.youtube.com/watch?v=gGooopCTmpg
