... Determination of forces acting on planing hulls in maneuvering has been turned into an interesting problem during the last decade. Different methods, based on mathematical or empirical approaches, are elicited in order to compute hydrodynamic forces and moments acting on the boat in different...

... Aluminum is a commonly used material for powerboats, especially military and commercial craft. It is also possibly the most common material for recreational boats under 18 feet or so and is well proven in this service, though the design and construction techniques of these small, light mass...

... The behavior of fast and relatively small ships in large following seas has been a serious concern for the operators for a long time now due to the possible occurrence of “broaching”. Due to the relatively low encounter frequency of these fast boats with respect to the large and high following...

... the model at constant speed, regardless of oscillating slamming loads, and allow the model to move only in heave and pitch. Typically in a planing hull seakeeping test the model is fixed in surge, i.e. restrained from moving backwards and forwards relative to the towing carriage. By contrast, planing boats...

... history using the statistical relationships of the Rayleigh statistics and operational wave conditions. In this analysis, the boats were categorized into three different operating regions, East Coast, West Coast, and Great Lakes based on differences in wave environment and further subdivided based...

... With waterways traditionally presenting the safest or the only possible route of travel, boats have been used for transportation for centuries along coastal and inland routes. At present, their significance has decreased due to development of other transport types, but transportation by small...

... This paper summarizes portions of a multi-year collaborative study on the dynamic stability of high-speed, shallow draft recreational boats, in which the author has played a small role. These boats are powered by outboard engines, and sometimes fitted with propeller tunnels to permit raising...

... notably the large motions and accelerations in a seaway. In recent years the high speed boat racing community has adopted transverse steps in the after bottom surfaces of the hulls to introduce air pockets and reduce drag. The size, number, and location of the steps have varied, but the concept of stepped...

... A surplus U.S. Coast Guard 26 foot Motor Surf Boat (MSB) was purchased and outfitted for use as a pleasure craft. This boat had been previously repowered by the Coast Guard and is capable of considerably higher speeds than the original design. The hull form has curved buttocks aft and a rounded...

... monohull craft with hull length below 30m, developed by Albatross Marine Design. Dimensions of hull are defined from usable areas and essential volumes, with recommendations provided for different architectural types of boats. Equations are proposed for weight groups based on hull dimensions, horsepower...

... The Royal Netherlands Sea Rescue Institution (KNRM) exploits a fleet of lifeboats around the North Sea coast of the Netherlands. The majority of this fleet consists nowadays of so called Rigid Inflatable Boats “RIB’s”. The largest vessels in the fleet are from the “Arie Visser” class...

... Tunnel hull boats, capable of achieving speeds up to 150 knots, are among the fastest waterborne vehicles. A tunnel hull configuration consists of a platform and two side hulls. The weight of this craft is supported mainly by hydrodynamic forces on the hulls and aerodynamic force on the platform...

... The U.S. Coast Guard’s 45 ft. Response Boat – Medium (RB-M) will replace the Coast Guard’s fleet of 41 ft. Utility Boats that have been in service for more than 30 years. Used for a wide range of missions including Search and Rescue (SAR) and Ports, Waterways and Coastal Security (PWCS), the RB...

... With an estimated 1.55 million personal watercraft (PWC) in use, these vessels make up only 8.6% of the U.S. recreational fleet. Yet in 2005, PWC accidents accounted for 1,007 out of a total of 3,451 serious boating injuries (29.2%) and 44 of a total of 163 non-drowning fatalities (27.0...
