Download the entire report in Hull Planking
Although hull structure was absent on the port side beyond the outer ceiling plank, removal of sediment underneath the broken frames revealed a 7.5 cm thick hull plank, heavily concreted with barnacles and corrosion. Pillars composed of iron corrosion and sand, reminiscent of Titanic’s “rusticles” (Ballard 1989:208), extend downwards from the fastener heads into the sterile sediments below the hull. A segment of the garboard strake (traca de aparadura), where it joins the keel at the bottom of the pump sump, was found to be 28.5 cm in width.
