Superyacht design is a multi-billion dollar business built on a handful of families and firms that have shaped the field for decades. This film traces that lineage back to John Bannenberg, widely credited as the father of modern yacht design for combining naval architecture with interior and exterior design into a single discipline. It follows his son Dicky Bannenberg and his design partner Simon Rowe as they run the studio today, walking through how a commission moves from a client's first vague wish through hull engineering, layout, and finish to a finished vessel. The film covers the shift toward active expedition cruising, as owners increasingly want yachts built for remote travel rather than just marina display, and shows how that changes hull design and onboard systems. Interviews with the Bannenberg and Rowe team sit alongside footage of drawings, models, and completed yachts, giving a practical look at a design world usually seen only in glossy brochures.
