RedactedNarrative: On 05-05-2015 at approximately 0625 hrs. Operator1 ( in stern ) and Subject1 ( in bow ), Boat 1 , of the Wilmington Rowing Center, were sculling in the Christiana River just above the Walnut St. Br. heading in an up river direction staying to the right side of center. Both persons observed three, 8 person sculls, labeled boat 1, 2 and 3 in diagram, University of Delaware Womens Rowing Club, approaching and could hear directions being given from a Coach''s Vessel, boat 5. One of the sculls was to the left of center heading downriver towards them, Operator1 and Subject1 were both concerned with the speed and direction of the vessel headed directly towards them and discussed their ability to yield and or stop as the 8 person was not stopping or slowing down. As the vessel''s got closer, Operator1 and Subject1 attempted to get attention of scull by yelling but had no effect. Assitant Coach of the U of D team did observe the direction of travel and saw that a collision was possible and did utilize his megaphone in hopes of stopping or redirecting but the coxswain, did not hear the direction nor did she see the other vessel until it was too late. The sculls oars on the port side of the 8 person made contact with the portside oars of Operator1 and Subject1. This contact caused the scull operated by Operator1 and Subject1 to overturn-capsize which led to Operator1 and Subject1 being ejected from their vessel. In the water now, Subject1 was brought onto the U of D Coach''s Launch being operated by Asst. Coach, Operator1 was unable to get into the launch due to extreme shoulder discomfort, Operator1 held onto the Launch boat and was brought over to the WYRA Dock and Wilm. Fire Dept. Marine Unit Personnel pulled Operator1 from the water onto the dock for evaluation. 
  Both Operator1 and Subject1 were transported by NCC Paramedics to St. Francis Hospital for evaluation,Subject1 was treated and released with soreness and diagnosed to have no injuries. Operator1 sustained a fractured left clavicle and was admitted and stayed overnight.
