with a full GRP inner molding, the space between these skins is filled with polyurethane
foam, this meant the boat is unsinkable in the event of taking on water. If the boat should become full of water she should still float according to the famous Archimedes
principle. The old naval wartime experience that "your ship is your best lifeboat" helps explain why designers thought that there was a need for an unsinkable yacht to promote further safety at sea. Fire could still sink such a vessel, this method of construction should be viewed as one of the many design features that can help promote safety-at-sea.
