Maritime Competence: The 70-20-10 rule
The 70-20-10 rule of skill development reveals a hard truth: only 10% of learning comes from classrooms and courses, 20% depends on mentorship, while 70% happens through real work. Shipping has overfed the 10%, while learning through the 70% is left to chance. This leads to skill-gaps that result in detentions, claims, accidents and observations. Can we bridge that gap—such that mentorship and experiential learning is part of daily operations, making competence measurable at sea?
