The Brazos Pilots recommend that all inbound vessels use a combination of tugs and thrusters so as to keep lateral control of the ship on the bow and the stern.  Most inbound vessels should use two tugs or one tug and a thruster.  Each ship and situation is unique and tug requirements are left to the master to arrange before arrival.  The final tug requirements will be decided upon during the Master/Pilot Exchange (MPX).  Departure tug requirements should be discussed with the pilot during arrival.
