Block Coefficient - Ship-Type Ranges
Block coefficient C_B reference ranges for common merchant ship types - the starting parameter for hull-form specification and resistance screening.
C_B range
0.80 – 0.86
Formula, assumptions, and limits
Full-form ships (C_B > 0.8) carry max cargo per LBP; fine-form (C_B < 0.6) minimise resistance at high speed. Concept-stage check vs ship-type peers.
