  15. Design Statements AVOID CONTRADICTION “In producing a new yacht, the central philosophy of Mills Design is that of developing and maintaining a focal design concept, the nature and integrity of which will determine the character of the finished product.” REDUCE COMPLICATION “In attempting to hold to a clear design concept we have found that with careful analysis complex requirements are often best satisfied with simple discrete solutions, simplicity being a key to success in competitive sailing.”

  16. Design Process Design Type Example: IRC 30-40’ The design type for this displacement range developed by Mills Design relies on a slim low wetted surface hull shape to provide minimum drag in the light and downwind, but with sufficient displacement for a large bulb to produce outstanding stability upwind in a breeze. That balance of weight, vcg, and sail area works not only to create a design with exceptional performance but to do so in a way that rating rules can digest most easily leading to the best possible performance/rating profile, especially on a Windward Leeward course in any wind speed.

  17. Design Process Design Type Example: IRC Mini-Maxi At larger sizes the freedom to concentrate on high performance combines with the inherent increase in stability afforded by the larger size and proportionate reduction in build weight to tilt the design cycle towards a power equation where target windspeed ranges and angles dictate the final balance of beam, wetted surface area, and drag. Designs looking to perform in lighter windspeeds opt for lower drag, while the design type that excels in windier more reaching courses is wider, lighter, and can benefit from specific design features like chines.
