Modern boat and ship design incorporates a variety of hull materials depending on the size application and expected life of the vessel.

Modern yacht hull design. A refined hull shape epitomizes the link between tradition and science. The 42 Ketch Zephyr in the drawing above is a perfect example of our Modern Classic approach to yacht design. Application of modern fluid mechanics and lightweight materials have enabled engineers to develop hull designs that minimize wake much more than older designs did.

For smaller recreational or shallow-sea activities polyethylene boats are a good choice both environmentally and economically. Sometimes called running strakes or lifting strakes these molded strips run lengthwise along the hull bottom and are virtually universal on modern planing boats. A wake is created because boats must push their way through water.

From January 20th to 28th there will be a large number of sailing yacht premieres in the exhibition halls 14 to 17 of boot Düsseldorf. The worlds largest boat show is the showcase of the boating industry especially for current design trends in sailing yachts and boats and the demands on modern yachts. Two variations on a modern downeast cruiser.

The owner of this particular yacht requested a white hull and it is a tribute to the design that a fine white finish can be applied that will not crack with any movement of the hull planking. Hard chine forms with greater beam and reduced length give improved performance in the calm water but experience high vertical accelerations in a seaway. Whether you are a cruiser or a racer it is a desirable characteristic.

This article is a review of some of these new wake minimizing hull designs. To highlight how these boat design principles play out Practical Sailor looks at classic sailboats such as the Bill Shaw-designed Pearson 32 Ericson 41 Valiant 40 and Peterson 44 and compares their keelsail ratios and lead values to more modern sailboat designs such as the Catalina Hunter Tartan and Beneteau. Many more sailing yacht concept designs can be found on our Prototypes web page.

Originally they were intended to help the deep-V hull reach planing speed since each strake has enough horizontal area to act like a tiny flat-bottom for lift. MODERN SAILBOAT DESIGN. Mid-Size Sailing Yachts.
