There are a variety of shapes and sizes for boat “hulls” or boat bottoms. A hull is designed to either displace or plane through the water. Small powerboats are usually built with planing hulls. They are designed to rise up and ride on top of the water at high speeds. Sailboats on the other hand use displacement hulls which allows the larger boat to move through the water smoothly.
Hull Types come in Flat bottom, Round bottom, Deep-V hull and Multi-hull.
Flat bottom hull boats are generally designed for slow speeds and calm waters. They tend to be less stable than other hull types in rough water.
Round bottom hull boats move smoothly through the water with little effort. A canoe is an example of a round bottom hull boat. Boaters have to be more cautious when loading, entering and exiting a round bottom boat because these boats can roll very easily.
Deep-V hull boats move through rough water, at higher speeds with a mother ride than a flat bottom or round bottom boat. This the most common hull type for powerboats. These boats require a larger engine than a flat or round bottom boat.
Multi-hull boats require plenty of room to steer and turn and are the most stable of the hull types. Pontoon boats and Catamarans are boats that use the multi-hull design.
Boats not only have different hull types, they are powered by different engine types (outboard, inboard and stern drives).
Outboard engines are typically two-stroke engines which require oil to be mixed with fuel to lubricate the engine, similar to gas powered weed eaters. An outboard engine is mounted on the transom of the boat and is controlled by a hand tiller or steering wheel which moves the entire engine as steering is changed.
Inboard engines are typically four-stroke automotive engines which have been modified for use on the water. These type engines are mounted inside the hull of the boat and powers the drive shaft which is connected to the propeller. Directly behind the propeller is the rudder which controls steering.
Stern Drive engines are commonly known as inboard/outboard engines. They have features found on both inboard and outboard engines. Stern drive engines use four-stroke automotive engines, modified for use on water, like inboard engines. Similar to outboard engines, the entire engine moves when the steering is adjusted. Stern drive engines are mounted inside the boat and attached through the transom.

In the United States auto market, the highest selling luxury brand is the Lexus. The brand is a division of the Japanese car company Toyota Motor Corporation. Its popularity among luxury car buyer is evident on the increasing acceptance of the Japanese brand in the United States auto scene.
One of the most notable models from the brand is the LS 460. The model is the ultra-luxury model of the brand. It made its debut at the 2006 New York International Auto Show (NYIAS) and since then has received positive reviews and feedbacks from consumers. Recently, the vehicle is named as the 2007 Best Engineered Vehicle by the Automotive Engineering International Magazine.
The Lexus LS 460 received the distinction after it received the most votes from AEI’s subscribers. Kevin Jost, the Editor-In-Chief of the magazine, has this to say about the award: “The voters had good reason for choosing the Lexus LS 460. ‘The LS 460 brings consumers at least nine world-firsts, including safety breakthroughs such as an advanced obstacle-detection system, emergency-steering assist and rear pre-crash systems. For driving pleasure, there’s also an eight-speed automatic transmission.” Indeed, the LS 460 is packed with a variety of features never before seen in a luxury vehicle.
One of the cutting edge features employed by the Lexus LS 460, as stated by Jost, is the eight-speed automatic transmission. This technology allows the vehicle to accelerate quickly since it provides smooth gear changes in with a wide variety of gear ratios. The smooth transmission also reduces the amount of power wasted thus increasing fuel efficiency.
The pre-crash safety systems are also a first for an automobile and the LS 460 provides such. This means that the vehicle not only provides a good performance but also protects its occupants. The obstacle-detection system provides drivers with sufficient warning to avoid possible accidents. The driver-monitoring system is also a feature of the Lexus LS 460. With this technology, safety can be checked basing on the driver’s capacity to properly drive the vehicle.
Safety features also include the emergency-steering assist which checks oversteer and understeer. With the use of sensors and advanced electronic programs, this vehicle can provide valuable steering assistance to avoid or minimize the risk of accidents.
Aside from the said features, the Lexus LS 460 also employs an intelligent powertrain control system. This system adapts to the engine’s need for power and other variables to provide good performance and respectable fuel efficiency. Rear collisions are also one of the most dangerous accidents a motorist can encounter.
To reduce the risk of severe injury caused by rear end collisions, the Lexus LS 460 features a rear pre-crash safety system. Its roof climate diffusers are also one of the advanced features that the LS 460 boasts of.

We live in the digital age where technology makes our lives easier each day. Advance medical equipments are created to help doctors treat patients, kitchen tools are innovated to make it easier for home makers, and
cars are made smarter to make driving easier for humans.
Automotive electronics paved the way for helpful features like anti-lock braking systems (ABS) and automatic weather adjustments which makes driving safer and more comfortable.
Car manufacturers spend about two thousand dollars in automotive electronics for every car that comes out of the assembly line. These automotive electronics transform the car into a vehicle with better performing engine, more adaptive entertainment systems, and safety features that are far more superior than its predecessors.
Automotive Electronics of the Modern Car
Control Area Network or CAN – There are several computers that run a modern car. The CAN is a network of computers that play vital roles in the different functions of the engine and its peripherals. The CAN serves as the bridge for the different computers so they can communicate with one another so everything are well coordinated. CAN controls the functions like cruise control, engine management, and the ABS.
Fuel Efficiency- automotive electronics can save a car owner hundreds of dollars in fuel consumption. This is done thru the EFI or Electronic Fuel Injection technology which ensures that the engine’s fuel consumption is at its optimal. In hybrid cars, a driver can easily switch from using gas and electronic power supply to run the vehicle.
Safety Devices- Most safety system is controlled by automotive electronics. Devices like the Acceleration Slip Regulation, Traction Control, Electronic Stability and Dynamic Steering wheel ensure the safety of the driver and the passengers. The simple but complicated timing of airbags during a road collision is also controlled by advanced automotive systems.
Added Features- Some cars today can even park themselves without any assistance from the driver. All the calculations are done by a computer making sure the car will not hit anything by making references to other cars and different objects in its surrounding.
One cannot imagine the evolution that took place with automotive electronics. The Apollo 11 which landed on the moon ran on a memory which is 150 kilobytes only. The sound systems of our cars today are running on 500 kilobytes of memory to ensuring our entertainment pleasure. Automotive electronics have gone far beyond entertainment and enhanced modern day vehicles in terms of safety, efficiency, and convenience.
The automotive industry projects billions of investments and sales in developing cars that are smarter, more fuel efficient and more environment-friendly in the future. Modern cars can be the answer to alleviate the adverse condition of the environment and the rising price of fuel all over the globe.
Cars are being developed to scan the traffic, the road, and all hazards so it can drive itself while the driver can do anything that he wants while in motion. The future cars can think for themselves with the aid of advanced automotive electronics. In that way, driving will be more than getting from one place to another.

Creating a replacement for the phenomenally successful; Model T Ford will always be recognized as one of the toughest tasks in all the entire history of the automobile industry. Later successes in an established industry are always easier – the groundwork has been done. It is early on in the marketing cycle of a
car , an industry or a sales territory is where the greatest efforts are usually required and the results success or failure are more dramatic. Mr. Henry Ford was confident and eccentric enough to want the Tin Lizzie to remain in production forever. Announced in 1908, the machine that put the world on wheels was destined to notch up just over 15 million sales before Mr. Ford accepted the fact a new model was vital and essential.”Sixty-four today and the biggest job of my life is ahead” Ford exclaimed as work began on the Model A, which was given the designation as the first car ever produced by his company , back in 1903. Believe it or not Ford Model T production ended nearly six months before the first of the newcomers was delivered : the hiatus appearing all the more extraordinary when you appreciate was then a one model
automotive car company. In terms of
cars for sale; the immense River Rouge plant built nothing for the almost a half of 1928.
Although far more complex than its predecessor , the parts count was 40 % higher, and most of these automotive components were new – the Model A is a miracle of simplicity by today’s modern standards – mechanical and of course electronic. Today’s vintage classic car fans appreciate the fact the Model A was designed to be fixed by blacksmiths of what was then the outback wilds of North Dakota. Key features of the Model A vehicle included a traditional frame-type suspension, transverse leaf springs, front and rear hydraulic dampers, a conventional ignition system, a safety-glass windshield, and a brake for each wheel. Like the Tin Lizzie, the newcomer was offered with an assortment of two door and door bodies, from a roadster and phaeton to sedan and taxi. Prices started at $ 460 in 1928.
It has been said about driving a Ford Model T that the driver should forget almost everything that they know about and are familiar with driving. For a driver sitting at the wheel of a Model T it is as if he is a driving novice. The only thing rather conventional about the setup for driving a Model T is the steering wheel. Not so with a Ford Model A. Anyone who can handle a standard manual transmission with proficiency need have no qualms about driving the Model A. The 3.3 liter engine’s four cylinders provide strong torque at very low engine revs, so there is no need to work up on down the three speed transmission. When one does, the shift’s silent simplicity will make you wonder why a vintage Bentley’s “cogs” can be so difficult to master.
The Ford Model A can maintain a cruising speed of 50 miles and hour with top bursts to a maximum of 65 miles per hour. This is all the more amazing when one considers that the engine is a 40 horsepower 4 cylinder engine running at 2200 revolutions per minute (rpm).
The Model A was remarkable in that it set a new standard with high quality that provided a rugged , more than reliable and characterful motoring , in an economical fashion all in return for more than a sensible amount for purchase price of an automotive product of its time from the market leader of its day – The Ford Motor Company.
