Drilling and nailing.
We had a new volunteer called John working on the boat today. He helped me with spiking up the bottoms to the garboard strakes (the first side planks which fit to the bottom boards). John mostly did the drilling and I crawled under the boat to drive up the big 10mm square, 11 inch long steel spikes. Stuart cut scarph joints and Ryan worked on the stove that he's preparing for fitting in one of the containers. Despite it raining quite a lot the day went well. We got 16 spikes driven up.
