RedactedNarrative: V1 struck an unknown object in the water.  The impact with the object ruptured the bottom of the hull on the port side, near the stern.  Due to the significant rupture in the fiberglass hull, the vessel began to quickly flood with water and capsized causing the damage to the vessel. The two occupants left the vessel then climbed back onto the capsized vessel until help came.  When v1 capsized everything inside the vessel was lost causing the damage to the property other then the vessel.
