I believe that is why the government is looking to lease a high speed ferry before the end of the year to supplement Largs Bay along with sharing Canterbury. I doubt whether any of the present Australian fat ships will be active next year. Manoora has already been stricken, Kanimbla will soon be struck with the lease of a high speed ferry, and Tobruk will be struck with the arrival of the Largs Bay.Unfortunatly its not possible / practical to cannabalise hull plating and structural tanks. They can change out pumps, motors etc until the cows come home but when the hull is being held together by paint it is a pretty pointless exercise.
The fat ships will most likely be Largs Bay, the high speed ferry, and sharing Canterbury until the arrival of the first Canberra LHD... Why waste more funds on the present lot?
