Technical Excellence: Essential Knowledge for Yacht Brokers
Module 3 of the CPYB Body of Knowledge
In yacht brokerage, technical knowledge separates the merely competent from the truly professional. Understanding vessel construction, systems, terminology, and operational characteristics enables brokers to serve clients effectively, communicate accurately with surveyors and technicians, and provide the informed guidance that clients deserve. This technical foundation is essential to the CPYB professional's expertise.
