Ro-Ro Vehicle Carrier (PCTC) CII

CII for Pure Car and Truck Carriers. MEPC.353(78) uses GT (not DWT) as capacity basis - reflects the low-density vehicle cargo. Reference line a=3627, c=0.590 from 30,000 GT, with capacity fixed at 57,700 GT and above; a=330, c=0.329 below 30,000 GT. Large PCTCs (8,000+ CEU) face tight rating bands under the MEPC.354(78) roro-cargo-vehicle d-vector.
