Design efficiency in the terrestrial environment of 90-degree angles, relatively unlimited space and stable platforms is fairly straightforward. But in the watery world of compound curves, compressed spaces and constant motion, balancing fashion, function and flow requires some nautical alchemy. Manufacturers seem to want to cover as many niches size-wise as possible, often relying on the expedient of upsizing or downsizing extant models. This year, the vessels that were simply upsized left the judges feeling as if the newfound space was wasted, and those downsized felt confused, with multiple sole levels, cramped sitting and dressing spaces, and an overall claustrophobic feel. The take-home message is that each design, while still incorporating signature features of the brand, should start as a blank piece of paper to achieve a holistic outcome.
