RedactedNarrative: RENTAL - 2006, 23' Fiberglass Rinker Model 226 Open Motorboat w/260 hp Inboard Engine 
  On 05/01/2014, sometime between 2:00 and 3:00 pm, according to the Operator, he had rented this vessel from Waypoint Boat Rentals. Operator had planned on returning the vessel that same evening. Prior to the boat sinking Operator and the 8 other vessel occupants had been hanging out in the water south of the I-90 bridge. They had been floating and listening to music for about 2-3 hours with the engine off and only the boat accessories on. 
  
  When they started the engine to head back the boat was not as responsive as it had been earlier and was traveling very slowly. Operator said that during this attempt to get moving he noticed about 2 cups of water come into the boat from the left back of the boat. He shut down the engine and looked into the engine compartment and saw that it was filling up with water. He tried again, unsuccessfully, to get the boat moving. The boat continued to fill with water so they called over to anther nearby boat that assisted them. Operator said that during the time of incident he tried twice to contact the boat rental company with no answer. He also tried calling vessel assist and again did not speak to anyone. 
  
  When Officers arrived all 9 occupants of the sinking vessel were aboard good sam vessel. The sinking vessel was almost fully submerged in a semi-horizontal position; the stern of the vessel was completely under water with the bow of the vessel having about 6 inches of gunwale out of the water. Officers confirmed that no one else was in the water. They attached a tow line to the bow eye of the vessel and began attempting to pump water out of the vessel. Officers were not able to bale water from the vessel at a productive rate. The vessel continued to sink further so Officers cut the line attaching the two vessels due to the rapid rate it seemed to be sinking. After several minutes, the sinking vessel came to rest in an apparently buoyant state with the stern completely submerged causing the vessel to float in a vertical position with only a few inches of the bow sticking out of the water. Officers re-attached a line to the sinking vessel and towed it to Proctor Landing where is was secured to the dock. 
  
  Officers transferred all occupants of the vessel to their vessel and transported them to the Mercer Island boat launch where they arranged for transportation. Officers stated that during their contact with the Operator (Operator) they did not smell any odor of intoxicants. His speech was clear, his eyes did not appear bloodshot or watery and they observed nothing to make them believe that Operator had been drinking. 
  
  According to the Boat Rental Agreement the rental vessel was rated for 10 passengers or 1440 pounds. Officers report that at the time of incident, the vessel was carrying 9 passengers who's weight totaled 1520 pounds.
