Vessel took on water and sank due to starboard and port Engine.  Vessel was 90% under water in 10 mins.  Operator used the bow thrusters to nose the bow into the jetty and ordered the 4 teenagers off the boat.  Operator and 1st mate remained on vessel and were picked up by USCG within minutes.  Contact with jetty caused a large gash in the port bow and vessel sank.  No injures.
