Scarab boats were popularly featured in the 1980s TV series Miami Vice. As of the second season of the series, the main character Sonny Crockett piloted a Wellcraft 38 Scarab KV. [ 3 ] In Riptide , the counterpart to the eponymous boat where the detectives work is the Ebb Tide, a 38' Scarab powered by KAAMA Power Systems. [ 4 ]
A jetboat is a boat propelled by a jet of water ejected from the back of the craft. Unlike a powerboat or motorboat that uses an external propeller in the water below or behind the boat, a jetboat draws the water from under the boat through an intake and into a pump-jet inside the boat, before expelling it through a nozzle at the stern.
Its Scarab line of boats, specifically, the Scarab 38 KV was featured on Miami Vice. [4] The Wellcraft Scarab 38 KVs were a 28-hued, twin 440-hp boat that sold for $130,000 in 1986. [4] As a result of the publicity the show gave Wellcraft, the company received "an onslaught of orders", increasing sales by 21 percent in one year. [4]
Yamaha numbers its models according to their make (in the case of the SuperJet, all models begin with the letters SJ) followed by the engine size (given in approximate cubic centimeters— the 650cc referred to as 650 and the 701cc referred to as 700) and the year in which the vehicle was made, given as either a one or two letter designation and increasing by one ‘letter' each full year ...
A Class 1 race-boat has twin inboard 1100hp engines and can reach speeds in excess of 257 km/h (160 mph). All boats are limited by a minimum weight of 4950 kg. The sport of powerboat racing has undergone unprecedented changes since the earliest recorded race in 1887 in Nice, France, organized by the Paris Sailing Club.
Super Boats - engines in the Super Boat class have no maximum size, but instead have a minimum size restriction. Normally aspirated engines must have a displacement of 6.5 litres (400 cubic inches), while forced induction (turbocharged or supercharged) engines must be at least 3.8 liters (235 cubic inches) in displacement.
A pump-jet, hydrojet, water jet, or jet drive uses a ducted propeller (axial-flow pump), centrifugal pump, or mixed flow pump to create a jet of water for propulsion. These incorporate an intake for source water and a nozzle to direct its flow out, generating momentum, and in most cases, employing thrust vectoring to steer the craft.
The boat was reported to reach a speed of four mph moving upstream. [7] [8] [9] On December 21, 1833, Irish engineer John Howard Kyan received a UK patent for propelling ships by a jet of water ejected from the stern. [10] In April 1932, Italian engineer Secondo Campini demonstrated a pump-jet propelled boat in Venice, Italy. The boat achieved ...
