The garboard plank is the first row of planking laid on the hull of a wooden boat, right next to the keel. It forms the critical connection between the keel and the rest of the boat's structure. This plank must be precisely shaped and fitted to ensure a watertight seal. Think of it as the foundation layer of a wooden ship's skin. Its integrity is essential for the boat's overall strength and seaworthiness. Without a solid garboard plank, the entire vessel is compromised.
