Fig. 2. A plan view diagram of the Britannic and an interpreted sonograph of the wreck. The sonograph acquired along a bow - stern direction over the deck of the wreck and shows the main structural components and superstructures of the ship- wreck. (1: bow, 2: stern, 3: the massive crack in the bow, 4: Wellin type davits, 5: giant lifeboat davits, 6: fore mast, 7: rear mast, 8, 9: funnels) (Papatheodorou et al., 2008a).
