Abstract High-speed ferries are now widely used for transporting both passengers and passengers and cars Numerous vessel designs such as catamaran¸ monohull hydrofoil air cushion surface effect foil assisted catamaran and small-waterplane-area twin-hull (SWATH) have been designed to meet these requirements
Why is hull speed not used in ship design?
- It is for this reason that hull speed is not used in present-day ship design; naval institutions nowadays favor more modern measurements of speed-to-length ratio, such as the Froude number. The formula for hull speed only needs the length of the vessel's waterline in feet, denoted as L_ext {waterline} Lwaterline.
How fast can a planing hull go?
- Recent planing hull tests speed realized an increase of 7–12 knots. River barges and ship fitted with an air injection system results are presented to show a 10–15% reduction in the frictional resistance. Graphs for making initial estimates for displacement hulls with bottom air injection are presented.
What is the maximum speed of a ferry?
- This supplies up to 13,000lbf thrust each engine on dry and 22,000lbf thrust each engine with afterburner engaged. Maximum speed reaches Mach 1.8 (1,190mph) with ranges out to 1,275 nautical miles. Ferry range is 1,800 nautical miles with a combat radius nearing 390 nautical miles.
How to calculate hull speed?
- Hull speed can be calculated by the following formula: vhull?1.34×LWL{displaystyle v_{hull}approx 1.34imes {sqrt {L_{WL}}}} where LWL{displaystyle L_{WL}}is the length of the waterline in feet, and vhull{displaystyle v_{hull}}is the hull speed of the vessel in knots
