Vortices inducing Settling with power  

The Mercy CFIT and crash site were almost in same location, with very light to no wind. Departures were 1-2 minutes apart.  If first pilot pulled straight up to avoid further contact with the water, could it be possible that the AC vortices induced could have disrupted the airflow in the Reach helicopter?  The 135 doesn’t have a large rotor diameter, but does obviously produce down wash.  The Reach ship would have have been heavy with 5 with sluggish response.
