We have been discussing smarter vessels. But what if the real bottleneck is not the ship but the way we operate it? What if the next leap in vessel efficiency will not come only from better hulls, cleaner propulsion, or more advanced technology? What if it will come from the people, teams, and and working practices behind them: the way companies design, communicate, test, decide, and adapt in this changing era? This presentation will explore where human expertise still matters most, how the human factor shapes vessel performance in ways no algorithm can yet replace, and whether the industry is becoming unrealistic about what technology can really deliver.
