Seam Compound

mate's picture

Caulking consists of filling the seams with cotton and oakum, and then applying seam compound. Seams between the planks have a bevel on the outside of the seam and the caulkers use caulking irons and a caulking mallet to apply the cotton and oakum. As that is done, you can actually hear the change in tone of the mallets. The boat actually tightens up and you can hear a ring.
Today they were doing some seam compound in the rain and this photo shows a shot of them applying it with a putty knife.
