Problem Occurs

If a Problem Occurs
Boat problems and accidents that occur offshore include collision, riding, overturning, fires, and engine failure. If you do not take appropriate action promptly if such a situation occurs, you will lead to a secondary trouble.
(1) Grasp the situation (personnel) With Drabble, we will promptly confirm whether there are any people who have run-off or injuries on our personnel and grasp the situation.
(2) Confirmation problems of the status (hull, engine, drive etc.) confirm and understand the situation of the hull, engine etc.
(3) Confirmation of location information
Confirm and understand current position.
First, the above initial response will be performed, but the basic priority is human life. If there is a human being or not, or if there is a water dropper, it can be rescued on its own or it can be navigated on its own, and the master's appropriate judgment of the situation is required.
(4) After confirming the rescue request status, if you decide that you can not respond by yourself, we will immediately request the marina for rescue, and will accurately report the situation, current location, and the presence or absence of an injured person.
(5) Implementation of measures to prevent secondary problems We will handle
as much as possible before the rescue arrives.
• If there are people with bruising, give first aid.
• If you are drifting due to engine trouble, put an anchor and stop the drifting.
• If the water is deep, insert a sea anchor to make it difficult for the waves to flow.
• If there is flooding, take action such as operating the bilge pump.
• Watch the situation around you.
• Prepare for towing.
Many problems with boats can not be navigated by themselves like this, from problems such as engine troubles and damage to drives and propellers to problems caused by rudimentary mistakes such as running out of fuel and rising batteries. One of the first things to consider when doing that is to prevent secondary problems. If the boat is swept away by wind or tide, it may be launched in the shallows, or there may be a collision with the ship in the harbor. In addition, depending on the sea area, it may cause a secondary accident called a capsize in response to a transverse wave.
A: Even if the anchor does not reach, the anchor may be heard in a situation where the water depth has become shallow by being flowed with the anchor inserted.
B: If you do not have a sea anchor, tie something to the rope such as a bucket or cooler back that will resist in the water.



Overturn Prevention of Triangular Wave



Overturn Prevention of Triangular Wave
The triangular wave is not directional and the periodicity is also unpredictable. Under such circumstances it is said that the speed of the rudder is effective, but increasing the time above the triangle wave will put the ship longer under unstable conditions, so at the top of the wave as much as possible Make it pass in a short time.
The triangle wave is like supporting the hull at a point on the top of the cone. Therefore, even the direction of overturning can not be expected in many cases, and it will be delayed in its treatment after it starts to tilt. (Refer to Fig. C)
Moreover, not only the triangular wave, but the trigger to lead to the overturn is complicated because many elements are intertwined in a complex manner, so proper maneuvering technology is required. Smaller boats have the effect of lowering the center of gravity just by lowering the attitude of the passenger, and by considering the balance between the left and right centers of gravity, boat stability is enhanced. But rather than that, it is important to choose a safer course and evacuate quickly, even if you are circling, if you decide that it is getting worse.

Name and role of each part of the boat

Name and role of each part of the boat
1 bow split
Structures that project further forward than bows. In the case of a small boat, an anchor roller or the like is attached to this part, and when winding up the anchor from there, the boat is made to jump forward so as not to damage the hull. It is also used when people move from the bow at quay walls etc.
2 stem
Prow. It is a member / part that forms the tip of the boat, and it has a very robust structure because a large force is applied at the part that cuts the waves.
3 keel
It is the most rigid structure of the boat because it is the part that secures the strength in the longitudinal direction of the boat in the part that corresponds to the human spine.
4 decks
About the deck. In some cases, it refers to the flat part of the boat. The bow deck is called the bow deck, and the stern deck is called the stern deck.
5 transom
Flat surface of the stern part. The outboard motor mounting plate is also called a transom board.
6 motor well
Point to the recessed area in front of the transom board. It is also a blank space part when the outboard motor moves to the left and right.
7 Hull
Hull.
8 Gunnel
Hull and deck junction. As it receives an impact at the time of berthing, it has a strong structure.
9 Bow rail
Anti-fall fences for fishing on the prow deck and for lifting and lowering anchors.
10 Bow thruster
A propeller mounted to propel the boat laterally. There are two cases: bow only and stern and both.
Hull part name and role

A history of Yamaha Spirit of Challenge


A history of Yamaha Spirit of Challenge
Introducing the 50-year history of Yamaha outboard motors (1960-2010)
In 2010, fifty years have passed since the birth of the first Yamaha outboard motor. Now Yamaha Motor has established itself as the world's outboard motor brand and in March of 2010 the company's total outboard production reached the momentous 9 million mark. But, the history of this half century of Yamaha outboard motors has not always been a smooth sailing, there have been rough waters along the way. In this long history of trying to build outboards that will bring true joy and satisfaction to the world's users, there were many difficulties and obstacles to overcome. But, through it all, the Yamaha people involved in engineering, manufacturing, marketing and service, kept the "Spirit of Challenge" that is at the heart of Yamaha Motor's corporate culture and overcame every obstacle. They continued to open up new horizons by taking on new challenges.
Challenge: An outboard development project started from scratch
The development project for the first Yamaha outboard motor began back in 1958 with a project staff of just two engineers. At the time, everything was new to them as they started from scratch to build the company's first marine engine. Soon after the project's start the staff grew in number and preparations began to move into production. At the time, however, there were no set standards for testing and the development process involved simply running the prototypes 24 hours a day and investigating how to improve the parts that broke down. The project had started from zero and its final result after overcoming many obstacles and hardships was Yamaha's first outboard motor model, the "P-7" that was marketed in Japan in 1960. In fact, however, it was still far from being a perfect outboard motor. For example, as one of the engineers from that time recalls, it was particularly loud and had a high level of vibration. This led to jokes from fishermen such as, “You can tell it is an outboard built by a musical instrument maker - it puts out quite a sound"

Yamaha 4-stroke Outboard Development

Yamaha 4-stroke outboard development, a history of technological innovation and environmental measures
Born in 1984 - the first Yamaha 4-stroke outboard motor
After winning a strong reputation as a builder of reliable 2-stroke outboard motors, Yamaha outboards began to win recognition as one of the world's leading brands thanks to the quality of its technological innovations to make engine performance eco-friendlier. During the 1990s, developed nations led the way in introducing regulations to limit the environmental impact of products, as exemplified by the emissions regulations adopted in the USA. This forced the outboard motor makers to direct their development efforts toward more eco-friendly engine technologies.
Prior to this trend, Yamaha had already developed and marketed its first 4-stroke outboard motor, the F9.9A, in Europe in 1984. With subsequent development, the F9.9 became the first outboard to clear the strict environmental regulations implemented in 1992 for boat engines used on Bodensee, the lake on the borders of Germany, Austria and Switzerland.
Another big advancement came in 1998 with the release of the 4-stroke model F100A powered by a DOHC 16-valve, in-line 4-cylinder engine that gave it the highest power output and best environmental performance in its class. Coming in a number of variations for specs like transom length and propeller type, this model made it possible to outfit a wide variety of different boat types around the world with 4-stroke engines. This F100A model opened the way to the development of increasingly larger horsepower 4-strokes and eventually the F350 that now tops the line-up as the flagship of Yamaha's 4-stroke outboard motors.
Surprising the world with Yamaha's big horsepower 4-stroke outboard technology
Amid the development of increasingly large 4-stroke outboards, the epoch-making model that completely changed the image of what a big-horsepower 4-stroke outboard could be was the F225A, which at its release had the largest horsepower of any production 4-stroke outboard in the world.
In the outboard motor industry at that time, it was generally accepted knowledge that it would be very difficult to build a viable 4-stroke outboard motor of over 200 horsepower. Yamaha engineers refused to accept that assumption, however. At the time of its release, the F225A featured a number of innovative technologies and revolutionary designs, including an exclusive combustion chamber design that enabled higher power output with a smaller displacement, a 60-degree V angle and internal injectors, plus a new engine layout with what came to be called the "In-bank Exhaust System" that positioned the exhaust system inside the V bank of the cylinders for greater compactness.
With this, Yamaha became the first 4-stroke outboard motor maker to try an engine layout that ran the exhaust pipes through the V bank and moved the intake system outside the block. Furthermore, by reducing the size and weight of many parts, changing the layout and using innovative new ideas and technologies throughout the engine, Yamaha succeeded in creating a 4-stroke outboard motor with higher output in a smaller package than anyone had thought possible before.
With ongoing efforts to apply new technologies in innovative designs, Yamaha succeeded in building a line-up of 4-stroke outboard motors ranging in size from 2.5 to 350 horsepower.
Then, in the autumn of 2010, Yamaha introduced its new V6/4.2 liter series. Once again, these models achieved extraordinary levels of weight reduction with new features like sleeveless cylinders made through new plasma fusion technology, all of which allowed Yamaha to build 4-stroke outboards with comparable weight to 2-strokes.
