Operator of V1 was entering the back water of Felsenthal NWR from the Ouachita River through Ebbey Cut going duck hunting.  Hunters are not allowed to enter the cut out of the river until 04:00am.  Operator of V1 along with several other vessels took off at the same time as they exited the cut into the flooded timber.  Operator moved to avoid a vessel; when he did another vessel pulled beside him.  This caused Operator of V1 to be unable to avoid a cyprus tree because of the wake of the second vessel.  V1 struck the cyprus tree causing the operator and passenger 1 to be ejected.  V1 then sank.  Other hunters stopped and provided assistance, they were able to retrieve V1, bilge the water out and tow it back to the ramp.
