D. The Efficiency of Ship Design
Table 8.9 states that ship design is an effective approach to avoid the ship from
the crash. The residual value for efficiency is at 20.5. It indicates the main value that
the ship design is an effective protection measure to avoid the ship from the crash.
Table 8.10 indicates the significant value at 0.000 and is below the P-value.
8.5 Conclusion
Between these two important elements in avoiding the ship from the crash, it shows
that ship operations are the most important criteria to be focused. The ship operations
such as changing courses in a combat condition are the extremely prominent variable, supported by variables for instance the officer of the watch action, condition
evaluation, hazard discovery, individual situation, and exhaustion [29]. The smallest
ship operations prominent variables include additional interruptions on the bridge,
