From the schematics at the top of page 117 one can easily see how the wetted surface of each type of hull section differs yet.

Catamaran hull width. It is shaped like a dustpan brush where the upper third is the handle. The hull lines of the new 85m Sports Cat Design 256 Mad Max Previously Carbon Copy. A word of caution.

Usually the waterline dimensions LWL and BWL are used for monohulls or for a single hull of a multihull. However this drag formula is generally not the limiting factor for catamaran hull speed. Wide hulls and a large overall beam will increase the overall righting moment of a catamaran.

EU Size factor ZWD 006 LWL ZWD 072. You need to know that the waterline length of one hull divided by the beam of one hull is 12. The cross-sectional profile of a hull will determine the wetted surface and drag.

For this study the length of asymmetrical catamarans and regular catamaran was changed to 40m it was made sure that parameters such as displacement and draft amid ship were kept constant for fair comparison. Excessive beam will reduce the fore and aft stability. The lower two-thirds of the island is a little more than two miles wide with a half-mile wider flare on its east side around 14th Street.

While the lengthbeam ratio of catamaran L BRC is between 22 and 32 a catamaran can be certified to A category if SF 40 000 and to B category if SF 15 000. Definition LB length divided by beam. Designers strive to compromise hull fineness ratios place heavy weights towards the CG Center of Gravity and engineer hull and overall beam to achieve a seaworthy balance which is safe yet provides ample liveaboard.

Whenever I attach the link to a message here it always takes it without screaming about size. Catamaran Sailboat Wide Bodied Hulls. Its distribution throughout the length of the boat will affect payload carrying ability and buoyancy.
