I am closing up the planking on the cat boat today. One side is all done. I have the shudder plank half installed on the other side. It is a tricky plank because it has to fit between two planks snugly. All the other planks only had to fit on one edge. I am taking a short break now and will be back to work in a couple minutes. Good to take a break on a job like this otherwise you just keep hammering on the plank trying to force it in were it does not want to go. Will eat lunch when it is done and then roll the boat outside and flip it over with the help of the tractor.
