A very good documentary well worth watching. I have read "Sailing Alone Around the World" several times and still learned a lot about the man.
He built, or re-built the Spray plank by plank "with a tree growing through her" (!) for $553 in 1895, according to the documentary. That equates to about $15,000 in today's money
. That is hard to imagine and must have been even harder to accomplish.
