Wet bike (Yamaha Waverunner: United States model)

The wet bike (すいじょう motorcycle) is a kind of the ships. I steer it by the operation of the handlebar and the physical balance of the vehicle driver using a water jet promotion system as driving force. I am classified in one-passenger (stand-upper type) and two kinds of .3 two people .4-passenger (runner bout type).

I point to the special small ship in the officer and small seaman method in Japan. I am called alias jet ski bike [1]. I am generally called a personal watercraft (PWC) in the English zone, and I am contained by a pleasure boat.

By the maker distinction, jet ski (Kawasaki), Malin jet (Yamaha), sea Doe (Bombardier) become the registered trademark. However, the name of "the jet ski" in particular may be used as a name to hint at the whole wet bike. [2]In addition, to sea Doe, I use the thing like the jet ski bike for an engine and a promotion system, but there are sports boat (4-10-passenger) which comprises an independent (not a thing to sit astride tandemly) seat every crew, and steers a ship by an annular steering and a thing to call. This type of boat is usually called "a jetboat" and is distinguished from a jet ski bike.

Summary

The history
American Mike Jacobs requests the development of the wet bike in the sales company of the Kawasaki motors Corporation United States which are a subsidiary of Kawasaki Heavy Industries saying "I want to be exciting and to commercialize the レクリエーショナル watercraft of the new type", and it is said that there is that a stand-upper type of the one riding was manufactured by an opening, but Canadian Bombardier Corporation releases the wet bike of the runner bout type called sea Doe in 1967.
Structure
I turn an impeller by an engine and have a water jet promotion system letting you take in water from an inhalational mouth (jet in take) of the lower hull and accelerate a current in a jet pump, and the body of rotation such as the screw which other ships have is not exposed to the hull outside.
Because I change the direction of the jet nozzle in conjunction with a steering wheel and circle, I have the special characteristic that I do not turn even if I cut a steering wheel in the accelerator off.
In late years, based on such a characteristic, the device which secures calm turning in the accelerator off is equipped a released main model with for dangerous evasion. The structure of the device is classified roughly into two, and I secure the number of revolutions of the engine under the constant condition and produce driving force and find turning characteristics and equip (Yamaha, Kawasaki) and the rear end of hull side with a small rudder linking a steering wheel, and there is (sea Doe).

Summary in Japan

I extract it from officer and small seaman method enforcement regulations Article 127

  • Being less than 4 meters in length and the small ship of less than 1.6 meters in width.
  • Small ship にあつては more than 2 capacity, an operation position and the sitting position of the person of embarkation are to be a thing of the series (there was the model of the cyclic steering in parallel called SC from Kawasaki).
  • It being a necessary small size ship to steer using the small ship or other physical balance using the flight control of the handlebar method.
  • Being a small ship to navigate by letting the jet-type pump using the internal combustion engine drive as a promotive body.
  • When a vehicle driver fell overboard, having the function that a promotive body stops automatically, have the function that does not greatly leave the vehicle driver whom the small size ship which is in a state which a vehicle driver is not fell into overboard.
License
Special small ship pilot (after law revision of June, 2003, it becomes the exclusive license, and it corrects impossibility with the boat license to steer and can steer it if I acquire it before revision)

An advantage and fault of the wet bike

Advantage
Advantages of the wet bikes for ships include the following.
  • Because the hull is small, I do not choose the stoppage place. It is hard to be a nuisance to the traffic even if it stops if it approaches to the edge.
  • A hull price is relatively low.
  • Fuel-efficient.
  • A premium and a tax, the maintenance cost including the inspection rate are relatively low.
  • Traffic is possible in the small waterway.
  • Passing is possible anywhere (but it is not a favorable driving method).
  • Bootleg turn is easy, and a radius of gyration is small.
  • I pull it on a trailer by car, and loading is allowed by the large ships such as cruisers.
Fault
  • Because a body is not covered with the hull, and it is exposed unlike a ship, I receive a shock at the time of accident directly.
  • I do a slide or a heel and fall into water when I take the wrong operation.
  • In the rainy day, comfort is spoiled remarkably.
  • It is fast-moving and lets neighboring people feel uneasiness and fear.
  • A lot of vehicle drivers having a low morals become the source of many problems including the noise / environmental problem to a fishery worker, a swimmer, neighborhood inhabitants.
  • There are many people which ride a car onto the beach as means of conveyance (in spite of entry of prohibition).

Way of enjoying wet bikes

There are various ways of enjoying as follows, but I observe laws and ordinances and local rule of each area of the sea, and it is necessary to note it not to be a nuisance to the neighborhood under any circumstance.

  • A fan ride: I navigate the neighborhood freely without determining an aim in particular.
  • Touring： I relatively navigate a long distance in group and several (name in imitation of a motorcycle).
  • Time trial: I install an aim thing (mark buoy) in the surface of the water and set up a course and compete with thyme for ability one by one.
  • A race: I run a go-around course in several people at the same time and compete for the order of arrival.
  • Free-style: I show various performances using a stand-upper type mainly. I evaluate the performance in time limits of 2 minutes in the meeting. The pro-jumps such as a barrel roll, the backflip skill is prosperous recently.
  • Wake board： Sports similar to waterskiing to fix both legs to the board, and to pull with a rope from a small ship.
  • Wake skating: Sports to get on in shoes to the side without fixing both legs to the board which is shorter than a wake board.

Special use

Other than the armed forces such as the Coast Guard, the navy or the Marine Corps such as water police or the firefighting, I deploy it for rescue use in the private rescue company and group. From mobility and ease of the acquisition, pirates or a terrorism group may use it as a surprise attack for the ships as well as a garrison and a regular army.

The opportunities when even events such as a boat or the surfing were used as a rescue boat increased, and a jet ski bike was prepared for for rescue in the world boat championship that hung it for from August to September in 2,005, and was held in the Nagara River of Kaizu-shi, Gifu recently by the cooperation of the hometown shop.

I use a jet ski bike for rescue at the Ichikawa-shi firefighting station. "A jet ski bike unit" to make with the lover of the jet ski bike for the first time in the whole country at the Miyazaki-shi firefighting station on June 3, 2007 started.

The Japanese blue by unit consisting of a jet ski bike lover or life savers started in 2010.

Risk of the wet bike

The wet bike contains the few risk in other vehicles by the structure and a dynamic characteristic. The feeling of strain to be born from there is one of the charm of the wet bike, but an image "to be antisocial as for the wet bike" is opening because a lover in defiance of a manner and a rule is founded extremely a lot, and accidents are greatly taken up again in media in a season. I easily illustrate by this passage about the "risk of the wet bike".

Risk for the crew

At first a wet bike does not have the brakes unlike a motorcycle of the land (the thing with brakes is generally rarer on a ship and stops by resistance of the water when I stop). It is particularly unstable at the time of the run low-speed as a characteristic and is easy to fall down. It is stable, but invites a fall into water, the fall of the vehicle driver and the overturn of the hull to some extent when it becomes the above-mentioned speed when the balance collapses by the shocks of the wave, and a vehicle driver cannot control balance. Because view becomes bad in the rainy day in particular, I note break in the weather, and it is necessary to run at low speed safely when it is unavoidable and does steerage at the time of rainy weather.

In addition, the wearing of the life jacket is duty, but the crew is thrown out on the occasion of an accident alone, and attention is necessary for the point that temperature becomes easy to be robbed of because I am shocked and will stop it and touch the water because the wet bike gets without having box structure to protect a crew like a two-wheeled vehicle running in the land with being bare. Besides, the thing that is full of that I return by the human power by oneself to the bank, and is difficult is an element enlarging the risk if I leave it with a wet bike even if there is the risk of the drowning without consciousness when I am thrown out into the sea once, and there is consciousness, and an engine does not operate.

The high mobility to have of the wet bike can leave for the direction escalating danger. For example, it is hard to attract attention on the surface of the water because the wet bike is smaller than a ship. While I fish, a fishing boat blocks up the course of the wet bike which closes the gap, and runs, and, as for most of the collision by blocking up the course of the wet bike which a fishing boat stopping on the surface of the water goes straight to, a fishing boat ship operator occurs by overlooking having done a wet bike. Because unnecessary and sudden high speed turns according to other vehicle drivers because I enjoy a turn than I say that the wet bike enjoys a cruise, it is easy to wake up the collision because of the action that I cannot expect.

In addition, the fatal and injury accident which the water which gushed out of a water jet propulsion system is in the body from anus, and injures the internal organs is up [3].

Risk for the neighborhood

As for the wet bike, the simplicity may give local people and a tourist serious noise damage without the unripe steerage by reckless driving and the unqualified person by the low rider of morals cutting off the back. In addition, I operate a wet bike in fishing ground neighborhood and damage the fishing ground and reduce fish catches and I steer it in beach neighborhood and wake up the collision with the swimmer, and the example that a rider and a swimmer suffer the death and a serious wound in is reported. 12 wet bikes chased a dolphin in the inlet where dolphin watching of Notojima was carried out in August, 2013 for approximately three hours, and the case that the figure of the dolphin was not seen in afterwards got up [4]. The action of the manner improvement activity by the control and a maker and the lover group by the Coast Guard and the water police is done, but the place that is the problem of the morals as the human being of the vehicle driver is finally big.

In addition, I have the influence that the current to take out of the wet bike and exhaust gas give an environmental aspect pointed out, and measures are taken. An action such as navigation regulation being enforced is done so that a current does not destroy the stream bed that is the spawning ground of the fish in Kisogawa, the Nagara River. In addition, about the exhaust gas, the most of the wet bike were equipped with an engine having high extremely environmental load called 2 stroke engines conventionally, but there is the severe environment, noise regulation of the United States which is an in late years main market, and the switch to 4 stroke engines (Yamaha MJ-FX) and 2 environment-adaptive stroke engines, the equipment for 吸排気 system of the low noise type advance. As of 2006, the wet bike performed a lineup of in Japan has 20 models (Yamaha 7, Kawasaki 4, sea Doe 9), but all the mainstream runner bouts of the three-passenger of the sale are equipped with 4 stroke engines, and, as for the thing equipped with 2 conventional stroke engines, it is in 4 models (one all capacity) and minority.

2 environment-adaptive stroke engines directly jet fuel in an engine combustion chamber, and they plan becoming it, and low pollution of the exhaust gas purifies exhaust gas by (ボンバルディエ SEADOO 3D-DI) and the combination of an electronic control type fuel injection device and the catalyst device which they comprised to the exhaust pipe, and they include (Yamaha MJ-GP1300R). In Japan, an action such as the use of 2 conventional stroke engines being performed prohibition (there are measures in progress) of by "regulations (Lake Biwa rule) about the adequacy of the use of leisure of Shiga Lake Biwa" is accomplished in Lake Biwa, and it seems that the use of 2 conventional stroke engines decreases.

Wet bike accident measures in Japan

Administrative measures
As measures by the administration, it limits a steering wet bike area by the regulations and officer of each local government and small seaman method and alcohol is tinged with it and supervises the driving. In addition, I perform a class in each place to steer it safely and call for the prevention of the accident. In Shiga, I perform a safe class when I perform steerage of a wet bike by the regulations in Lake Biwa. Steerage does not come to be possible in Lake Biwa when I do not attend this.
Injury, insurance against loss
Because a small ship (including the wet bike) is not obliged to carry out participation of the insurance, a premium soars because an insurance participation rate is low, and a vicious circle that an insurance participation rate decreases more thereby has it pointed out, and a good plan for insurance participation rates is considered.
Safety measures by a magazine and the rider
In the group of riders who are the direct user of the wet bike, there is a place working on enlightenment through voluntary events. Which "I do not cause an accident" is not merely only a thing of the passiveness "not to be in an accident", and the active things such as the acquisition of the relief technology are included, for example, in such an activity.
In addition, I often place features about the safety in the wet bike magazines which assume a rider a market.

Safety measures by the maker

I push forward development with the maker of the wet bike aiming at the safe wet bike, and, in the recent main model, the measures such as the output control units which considered a device (cf. said article "structure" column) or a beginner assisting steerage in the low speed are equipped with.

Riding gear

I say the equipment to add to the verge body getting on a wet bike. I call the thing belonging to clothing "riding wear". Exclusive riding wear is commercially available. They are cut to the embarkation posture of the wet bike, and the protection nature is thought about and has a function suitable for riding. The rider and the fellow passenger were required to wear a life jacket by license revision of 2002 in Japan. When I violate it, I will receive the administrative deposition of the operation stop within six months.
