User:John Hutton/Triple plank Kauri

Triple plank Kauri is a yacht hull construction method unique to New Zealand. The method consists of using three layers (or planks) of Kauri nailed together using copper nails or roves. Hulls are built upside down over timber formers no ribs are needed to maintain shape although a series of stringers sometimes called longuerons run fore and aft. The Triple Plank Kauri system produces yacht hulls of great strength and durability.
