Shipwright Aaron spiles the shutter plank on Mary E‘s starboard side. The shutter plank is a plank that fits between two other planks that are already fastened to the vessel. Planking often goes on from the bottom up and the top down simultaneously, so there is always at least one shutter plank per side. The shutter plank requires different techniques to clamp it to the vessel because the framing above and below it is less accessible due to the other planks bring there.
