The boat has no nails or screws; entirely wood lashed together with rope
they're sailing around the pacific again, saw them last weekend when they stopped in seattle. toured the boat, went to a presentation they did about the history and navigation
met one of the 13 crew aboard, 70-something year old man who has been sailing on this boat for decades. He had some really good stories!
