Prefit software is not used as it will give and undesirable result while importing catamaran hull marker data.

Catamaran hull form. The vessel features a very slender central hull and two smaller hulls or sponsons on either side. In this area of hull form savings of up to 15 to 20 in power fuel costs can be realized for an optimally designed vessel. An interesting feature was the development of the catamaran hull form to achieve a speed of 18 knots in the shallow waters of the Northern German Waddensea with a limited amount of power.

We want asymmetric water planes and a reasonably flat rocker to minimise pitching. Transverse stiffness is set to 2 as we are creating a chine hull form. This ship designer must pay close attention to the fundamentals of the hull form and appendages and must evaluate the construction and operating costs as he proceeds through the various design decisions.

The most important catamaran design hull shape factor is the Prismatic Coefficient Cp. After quite enough fairing is done the required hull form is obtained in a msd format. Hull fore features configuration of single-hull vessel while aft has catamaran configuration.

Instinctively you might think that fine ends would be faster as they would cut through the water better. MVentura Hull Form 13 Catamaran Types of Hull. CATAMARAN HULL-FORM DESIGN A design procedure is developed on the concept of an effective hull form.

Its a given that catamarans are more sensitive to weight and loading than monohulls. A hull too skinny will have higher drag from skin friction. Fore outer boards and deck decks smoothly change.

This means the hull forms are optimised as long narrow displacement shapes. The below-water-level hull form influences the fluid flow characteristics around the ship which either increases or decreases the total resistance. In the initial stage of designing a vessel for transporting 150 to 250 passengers both a monohull and a catamaran were considered.
