They say good things come in threes. Dutch studio Sinot Yacht Architecture & Design has embraced this theory with its “Beach” concept with a family of superyachts available in three defined sizes.

Designer Sander Sinot even has bigger goals, with hopes to sell multiple sizes to the same owners. “There are many families who own several yachts between them, but most of the boats differ in terms of space, accommodation and design philosophy,” Sinot told Robb Report. “It makes sense to build equal designs in variable sizes to create a cohesive family of yachts.”

Maybe. One advantage is that building a yacht based on a fully engineered platform saves owners time and money, especially if built as part of a series where parts are ordered in bulk.
