65 Foot T-boat Drydock Repair
Background
Three single screw 65 foot steel vessels are used for ship handling training at the USCG Academy in New London, CT. The vessels were built in 1953 by Higgins Ship Building in New Orleans and referred to as T-boats. The goal of the shiphandling program is to expose cadets to the man overboard (MOB), anchoring, emergency steering and mooring and unmooring evolutions onboard the 65’ T-Boat.
Each student is introduced to the principles of single screw shiphandling, shipboard engineering and deck seamanship while continuing to grow and develop as leaders of peer leaders. The program culminates with a final exercise during which the students plan, brief and execute an inland/coastal transit of the Thames River and Fisher’s Island Sound. During the exercise the students perform a variety of routine shiphandling and seamanship evolutions while also responding to limited shipboard emergencies.
