I. INCIDENT BRIEF
At approximately 1500 on 03 October 2015 the DUKW, an amphibious passenger vehicle, SD 5 was transiting southbound on the Delaware River in Philadelphia, PA with 12 POB on a sight seeing trip. As the master turned the vessel northbound to return to the boat ramp the wave height in the river began to increase with the changing tide/current and wind conditions. The vessel took a 3-4' wave over the bow and water entered the open hood for the engine compartment causing the engine to stall out, setting the vessel adrift. The master radioed the companies marc boat for assistance. The vessel was immediately towed back to the Race Street boat ramp without further incident. The master was able to start the engine once the vessel was back at the boat ramp and the vessel pulled out of the river under it's own power. The cause of the incident was determined to be the rapidly worsening river conditions while the vessel was out on it's tour route and for the masters of both vessels failure to anticipate the change in the weather conditions. The change of the tide from slack to flood and the strong northerly winds caused the waves to quickly build and exceeded the restriction on the vessels COI.
