The 3rd Sanya International Boat Show and Ocean Culture Fair opened in the Hainan Island port city on December 24, 2009. Many internationally-renowned builders displayed their products such as Sunseeker of Britain and Bombardier of Canada; there were also several luxury yacht brands of Italy??s Faraday.
Sanya Vice Mayor Li Boqing said Hainan enjoyed very broad sea areas and a unique natural environment for the development of marine tourism.

Jetboats were originally designed by Sir William Hamilton (who developed a waterjet in 1954) for operation in the fast-flowing and shallow rivers of New Zealand, specifically to overcome the problem of propellers striking rocks in such waters. Previous attempts at waterjet propulsion had very short lifetimes, generally due to the inefficient design of the units and the fact that they offered few advantages over conventional propellers.

Jet boats are highly maneuverable, and many can, from full speed, be reversed and brought to a stop within little more than their own length, in a maneuver known as a "crash stop". There is no engineering limit to the size of jet boats, though the validity of their use depends a lot on the type of application.
With safety being our highest priority the vendor may decide to cancel the trip due to unfavorable weather conditions. During the ten days?? fair, twenty-five exhibiting companies displayed yachts from the US, Britain, Italy, France, Australia, Hong Kong and Taiwan.
Chen Runqin from Hong Kong-Asia Ocean Culture (Hong Kong) Co., Ltd, some boat-related activities would also be held such as water motorboat races and a forum on ?°Opportunities and Development of Hainan??s Boat Industry?±. The Sanya Municipal Government gives full support for the development of the boat-related economy. Local Get Ratings Reviews on Boat Rental Charter with Photos, Maps, Driving Directions and more.
Unlike a powerboat or motorboat that uses a propeller in the water below or behind the boat, a jetboat draws the water from under the boat into a pump-jet inside the boat, then expels it through a nozzle at the stern.
Unlike these previous waterjet developments, such as Campini's and the Hanley Hydrojet, Hamilton had a specific need for a propulsion system to operate in very shallow water, and the waterjet proved to be the ideal solution. The well known Hamilton turn or "jet spin" is a high speed maneuver where the boat's engine throttle is cut, the steering is turned sharply and the throttle opened again causing the boat to spin quickly around with a large spray of water.

Classic prop-drives are generally more efficient and economical at low speeds (up to about 20 knots) but as boat speed increases beyond this the extra hull resistance generated by struts, rudders, shafts etc means waterjets are more efficient in the 20-50 knot range.
South Africa's Valour class frigates (approximately 120m long) are the biggest jet-propelled vessels so far. This decision is entirely up to the vendor and will be asset the day of and up to the moments before the activity. Hopefully, the 10-day exhibition and other activities will further promote the marine tourism industry in Hainan, he added. From this the popularity of the jet unit and jetboat increased rapidly, and through further developments it was found the waterjet offered several other advantages over propellers for a wide range of vessel types, and as such waterjets are used widely today for many high speed vessels including passenger ferries, rescue craft, patrol boats and offshore supply vessels. Also, in situations where you need very large propellers turning at slow speeds (such as tug boats) the equivalent size waterjet would be simply too big to be practical.
With its low draft (operating water depth) and high speed, jet boats are one of the best ways to see Ocean City and its bays. For these reasons the vast majority of waterjet units are installed in high speed vessels and in particular situations where shallow draught, maneuverability and load flexibility are main concerns.
