This job was easy. The 'Gains' took about 10 minutes on plank and 10 minutes on the hull. They start from about 350mm from stem. Straight edge on plank and plane down as required. My bevel plane was bought on Trade-Me. Thanks to my apprentice for her help. I am lucky she is willing to mix and fillet epoxy and occasionally use the drills!
I am going to holt planking at the 2nd row for a short while. I have decided I am going to epoxy barrier coat my wood under the floorboards and leave unpainted. Will be quicker than painting. Easier to repair. Will also finish all fillets, forward floor and anchor floor. All these jobs will be easier with the top two rows of planks off.
