The sailboat, The Golden Rule, has a history of activism. In the late 1950s, a crew tried to sail to the Marshall Islands to stop nuclear testing. They were stopped and put behind bars, but their efforts helped to create national change.  

"They raised worldwide concern and they built support for the partial Nuclear Test Ban Treaty that was signed in 1963 by President Kennedy, along with the UK and the USSR. . . that made it illegal to test nuclear weapons in the air, underwater or in space," Gerry Condon a member of the board of directors for Veterans for Peace, the organization that organizes the project, said.  

Now, the boat sails to tell its history, but also to warn against the potential dangers of nuclear war and weapons.  

"A nuclear winter -- so much dust and soot would go up into the air, would block the sun for totally or at least partially for ten years, which would cool down the earth, which would make it impossible for it to grow crops, and the estimated 2 billion people would die from starvation. . . That could happen tomorrow. So it is very urgent," Condon said.

One crew member, Suzanne Murphy, said that the message has been welcomed at their destinations.  

“The communities that come out to greet us are really pumped to see us, and we're really happy to see them. And I, I hope that it's doing what it should be doing, and it appears that it is -- that people are waking up and realizing how detrimental nuclear weapons are to our future,” Murphy said.
