    I've been working on a dead man's boat for a while now. Before he died
    he asked me to take it away. I might have told the back story here
    before so I'll try to make it short.

    My buddy Gary tried to get me to buy his boat a few times. His son had
    taken it all apart all and then had to "go away." Gary (retired old
    Vietnam era vet) would walk out and start to work on it, but lose heart.
    One day he called me up and told me to get it out of his driveway. He
    was tired of looking at it.

    I didn't want it. I've got to many projects in the works, and two more
    boats I want to build from scratch. The last thing I wanted was another project. When I heard the tone in his voice I knew the only right thing
    to do was to give him a few bucks and let it sit in my driveway. I
    figured I could quadruple my money if I sold the outboard and scrapped
    the hull for salvage.

    The thing is in the back of my mind I wanted to put it back together and
    take him fishing in his old boat. I started working on it, but very
    slowly over the course of a few years. Then Gary's cancer came back.
    He had almost ten good years in remission, but it came back bad. This
    time the docs said they could try chemo, but don't count on it.

    One day I called him to ask a few questions... I was working on it again because I knew Gary's cancer was going to kill him this time. His
    daughter answered and said this was it. If I wanted to see him come
    now. I spent a couple hours with my friend holding his hand and
    babysitting his grandson while his daughter got away to run some errands
    and do some necessary shopping. That was his last day on earth. His
    daughter called me the next day to let me know he was gone.

    I guess that wasn't so short after all. I've been working on it lately.
    I'm making it "better" or maybe extending the time before it goes to the
    scrap heap. All the wood had to go. It had a plywood sole and plywood
    decks in an aluminum boat. Its okay if you don't mind re-carpeting
    every couple years, and re-decking periodically. I got rid of all that plywood. used a plasma cutter to blow out all the steel screws that
    should have never been used, and built the sub floor structure on the
    sole. I put all that back together with stainless steel closed end
    blind rivet.

    More recently I took out all the foam, and vacuumed out all the debris.
    Then I cut a one piece sole out of 0.080" aluminum sheet, laid it in
    placed, and drilled all the rivet holes to secure it to the ribs. Then
    I took it back out.

    I vacuumed out all metal chips from drilling holes, stuck the decent
    foam blocks back in place and prepared to pour some more flotation foam.
    The foam I'd had on the shelf for a dozen years wasn't any good any
    more. Today I finally poured some more foam, and laid the sole back in
    place.

    I knew it was going to be a difficult task, but I'm forcing the holes
    back into alignment for another round of closed end stainless blind
    rivets to nail down the sole. I'm about half done. I started by using
    some punches to align some holes in the back, secured just one rivet,
    and then I forced some holes into position on the front. So with
    leverage and a hammer I've gotten every hole to line up well enough I
    could atleast tap the rivet into place with a hammer. Over half the
    rivets are in.

    Before anybody tells me stainless can still react with aluminum in a wet environment. Yes. Yes it can. Not like plain steel, copper, or some
    other metals, but it can very slowly. This is a fresh water application
    so more slowly than that even, and this is inside the boat. Not through
    the hull. I have regular aluminum rivets, a buck and an air hammer for
    those applications. Also, about 75% of the original aluminum rivets
    that held the sub floor structure (ribs and rib stiffeners) had broken.
    The stainless rivets won't break any time soon.

    Well, I guess my break is over. I gotta go put in the rest of those
    rivets.
