RedactedNarrative: Vessel was traveling approximately 30-40 miles per hour when the fiberglass on the bottom of the vessel failed (delaminated) causing the vessel to stop suddenly, ejecting the operator and the passenger. The vessel sank in shallow water, but was moved to the shoreline shortly after. There were no serious injuries.
  
  
  The investigation revealed that a portion of the stepped fiberglass hull, near mid ship forward of the step, delaminated. This hull failure allowed the pressure from the water to push the fiberglass inward, into the bilge. Because of this, the 1-2 in. step in the hull acted as a brake and caused the vessel to stop suddenly due to the significant resistance. 
  
  Operator stated that a friend of his did the fiberglass work recently and this was only the second time the vessel had been used since the repairs were completed. It is not believed that the vessel struck anything prior to the accident. 
  
  Subject was ejected forward when the vessel stopped and he impacted the bow of the vessel causing minor cuts and bruising to his upper legs.
