ENTERPRISE Off - The Survey Ship ENTERPRISE has departed on nine month deployment to the Arabian Gulf.       The survey ship will have as the primary tasking military data gathering but will also act as a deterrent to illegal activity by increasing security and preventing conflict.  The ship sailed from Falmouth with a brand new nine metre survey motor boat named SPITFIRE onboard which effectively doubles the ability to collect data.    The ENTERPRISE was in Falmouth for a month while work has been conducted on the davit used to lift the new motor boat in and out of the water.   The ENTERPRISE operates a watch rotation system and has a crew of 75 men and women, with 50 on board at any one time. The watches are changed while the ship is still deployed, giving the crews a set time of duty and leave.
