Most of the marine yacht boats have diesel powered engines, but the latest concept of boat shown by Mercury Marine at the Miami International Boat Show somehow different. The hybrid boats will have lithium-ion batteries onboard the vessel to powers the boat’s two 100hp electric engines. The hybrid boats with be equipped with full SmartCraft controls such as joystick docking, the Mercury’s Hybrid Concept Vessel glided out of its slip like it was drifting in the wind, making virtually no sound, no smoke and no smell.
Yet, the driver of the boat simply used the Zeus joystick control to pivot in the channel and head out the harbour gap under electric power, even through stiff winds.
You would never know that it was a Hybrid boat from the appearance or the performance and the penalties in weight or increased cost are projected to be well within the envelope of what buyers are comfortable with.
No other boat of its size offers as much liveable space and, in many ways, she is a great alternative to a beach house. Electric boats are almost maintenance free, they are reliable, cheap to run and easy to operate. While a significant majority of water vessels are powered by diesel engines, with sail power and gasoline engines also remaining popular, boats powered by electricity have been used for over 120 years.
The first electric boat was developed by Moritz von Jacobi in 1839 in St Petersburg, Russia - a 24-foot (7.3 m) boat which carried 14 passengers at 3 mph. It took more than 30 years of battery and motor development before they began to be deployed in any numbers.
Electric boats had an early period of popularity between around 1890 and 1920, before the emergence of the internal combustion engine drove them out of most applications. Most of the electric boats of this era were small passenger boats on non-tidal waters at a time when the only power alternative was steam.
In a few situations, the use of electric boats has persisted from the early 20th century to the present day. In the US, the Electric Boat Company was founded in 1899 and built the first submarine purchased by the U.S. The use of combined fuel and electric propulsion has gradually been extended over the years to the extent that some modern liners such as the Queen Mary 2 use only electric motors, powered by diesel and gas turbine engines. The use of electricity alone to power boats stagnated apart from their outboard use as trolling motors until the Duffy Electric Boat Company of California started mass producing small electric craft in 1968. The main components of the drive system of any electrically powered boat are similar in all cases, and similar to the options available for any electric vehicle. Solar panels can be built into the boat in reasonable areas in the deck, cabin roof or as awnings. Towed generators are common on long-distance cruising yachts and can generate a lot of power when travelling under sail. If the boat has an internal combustion engine anyway, then its alternator will provide significant charge when it is running. There have been significant technical advances in battery technology in recent years, and more are to be expected in the future. Valve-regulated lead-acid (VRLA) batteries, usually known as sealed lead-acid, Gel, or AGM batteries, minimize the risk of spillage, and gases are only vented when the batteries are overcharged.
Nickel metal hydride, lithium-ion and other solid-state batteries are becoming available, but are still expensive. In conventional electric boats the size of the battery bank determines the range of the boat under electric power alone. Drive trainTraditional boats use an inboard motor powering a propeller though a propeller shaft complete with bearings and seals. There are as many types of electric boat as there are boats with any other method of propulsion, but some types are significant for various reasons. Historical and restored electric boats exist and are often important projects for those involved. Electric boats, with their limited range and performance, have tended to be used mostly on inland waterways, where their complete lack of local pollution is a significant advantage. Electric outboards and trolling motors have been available for some years at prices from about $100 (US) up to several thousand. Cruising yachts usually have an auxiliary engine, and there are two main uses for it: One is to power ahead or motor-sail at sea when the wind is light or from the wrong direction. There is a third potential use for a diesel auxiliary and that is to charge the batteries, when they suddenly start to wane far from shore in the middle of the night, or at anchor after some days of living aboard.
All the component parts of any boat have to be manufactured and will eventually have to be disposed of. The May 2010 edition of Classic Boat magazine carried a pro and con article entitled Electric debate. Campbell asserts that the lack of pollution from an electric boat "reeks of nimbyism" as "the discharge is all in someone else's back yard" and that the provision of re-charging points may involve digging up miles of habitat. Campbell discusses the pollution that "traditional" batteries put into the water when a boat sinks, but Desmond says that electric boats are no more liable to sinking than other types and lists the leakage of fuel, engine oil and coolant additives as inevitable when an internal-combustion-engined boat sinks. The article mentions 25% and 30% discounts being offered to electric boaters by the UK Environment Agency and the Broads Authority and that battery powered vehicles have 3⁄5 the carbon footprint of their petrol equivalents. In 2010, the Turanor PlanetSolar, a 35 metre long, 26 metre wide catamaran yacht powered by 537 square metres of solar panels, was unveiled. Japan's biggest shipping line Nippon Yusen and Nippon Oil Corporation said solar panels capable of generating 40 kilowatts of electricity would be placed on top of a 60,000 tonne car carrier ship to be used by Toyota Motor Corporation. The Monaco yacht company Wally has announced a "gigayacht" designed for billionaires torn between buying a mansion and a superyacht.
Why hasn’t the Texas senator managed to unite the Republican Party in opposition to Donald Trump? Former House Speaker John Boehner seems to be enjoying his retirement—and wouldn’t you, after what he went through in Washington? A professor of cognitive science argues that the world is nothing like the one we experience through our senses. And now Donald Trump’s many and fierce opponents in the Republican Party and the conservative movement face the hour of decision. There’s a common perception that women siphon off the wealth of their exes and go on to live in comfort. A 38-year-old woman living in Everett, Washington recently told me that nine years ago, she had a well-paying job, immaculate credit, substantial savings, and a happy marriage. Seven years later, her husband told her to leave their house, and filed for a divorce she couldn’t afford.


Tennessee is just the latest state to pass legislation claiming to protect conservatives who object to LGBT relationships and identity. The Nobel-winning economist discusses the Fed, the election, and the role of economists in fixing inequality. In 2015 alone, Stiglitz wrote two books on the topic, The Great Divide and Rewriting the Rules of the American Economy, based on years of research and expertise about the intersection of economic theory, markets, and policy.
Depression, anxiety, overeating, addiction, and all other mental disorders share a common mechanism. The Solar Boat Company is the leading supplier and installer of electric motors on narrowboats and barges on the English cs. Up for sale is a brand new 50 watts solar panel with junction box, alumnium fram, protected with tempered glass, presented by ***** This panel is pretty thin and light weight. We can make the pv technology solar panels size according to customer special requirements. They are showcasing the concept possibility of hybrid engine technology for yachts or boats.
These lithium-ion batteries can be recharged by either using on shore electricity or using an array of solar panels fitted on the deck and hardtop of the boats.
Imagine seeing yourself and your children and friends racing round in kayaks or paddle boards. It is estimated by the motor manufacturers that the only maintenance required is the renewal of the main bearing in 20 years time. Being able to open the front doors fully and motor a slow speeds in absolute silence is a surreal feeling.
Electric boats were very popular from the 1880s until the 1920s, when the internal combustion engine took dominance.
For example, an 1893 pleasure map of the Thames shows 8 "charging stations for electric launches" between Kew (Strand-on-the-Green) and Reading (Caversham).
One of the largest in Britain, and the only surviving example, is the Mary Gordon which was built on the Thames for Leeds City Council for use on the Roundhay Park Lake. The advantages include being able to run the fuel engines at an optimal speed at all times and being able to mount the electric motor in a pod which may be rotated by 360° for increased manoeuvrability. Duffy Boats has produced over 10,000 electric powered boats to date and is producing well over 300 per year today. Shore-based power stations are subject to much stricter environmental controls than the average marine diesel or outboard motor. Some solar panels, or photovoltaic arrays, can be flexible enough to fit to slightly curved surfaces and can be ordered in unusual shapes and sizes.
If an electric boat has sails as well, and will be used in deep water (deeper than about 15 m or 50 ft), then a towed generator can help build up battery charge while sailing (there is no point in trailing such a generator while under electric propulsion as the extra drag from the generator would waste more electricity than it generates).
There are safety considerations regarding the spinning blades, especially in a strong wind. Two schemes are in use: the combustion engine and the electric motor are both coupled to the drive, or the combustion engine drives a separate generator only, for charging the storage batteries.
This ensures that the batteries are charged at the maximum rate that they safely can stand when the power is available.
These batteries require minimal maintenance, as they cannot and usually do not need to be refilled with water. These are the kind of batteries currently common in rechargeable hand tools like drills and screwdrivers, but they are relatively new to this environment.
Often a gear reduction is incorporated in order to be able to use a larger more efficient propeller. Electric drives are also available as auxiliary propulsion for sailing yachts on inland waters. These require external batteries in the bottom of the boat, but are otherwise practical one-piece items. The other is to provide the last 10 minutes or so of propulsion when the boat is in port and needs to be manoeuvred into a tight berth in a crowded and confined marina or harbour. In this case, where this kind of use is to be expected, perhaps on a larger cruising yacht, then a combined diesel-electric solution may be designed from the start.
The available sunlight is almost always converted to electricity by solar cells, temporarily stored in accumulator batteries, and used to drive a propeller through an electric motor. Some pollution and use of other energy sources are inevitable during these stages of the boat's life and electric boats are no exception. Jamie Campbell argued against electric boating on four main counts, which were rebuffed by Kevin Desmond and Ian Rutter of the Electric Boat Association.
Desmond responds that while there is no doubt that rechargeable batteries derive their energy from power stations (when not charged on board by solar and wind generation), noisier internal-combustion-engined boats obtain their fuel from even further away and that, once installed a power cable is less environmentally disruptive than a petrol station.
While Campbell refers to heavy batteries requiring a "load-bearing hull" and "cranky, even unseaworthy vessels", Desmond points out that electric boaters tend to prefer efficient, low-wash hull forms that are more friendly to river banks. Rutter points to the "very nasty cocktail of pollutants" that come out of a diesel wet exhaust in normal use. On May 4, 2012 it completed a 60,023 kilometres (37,297 mi) circumnavigation of the Earth in Monaco after 585 days and visiting 28 different countries, without using any fossil fuel.
The Why 58 x 38 is designed to have an autonomous cruising range of 12,000 miles at 12 knots by means of 900m2 of solar panels which generate 150 kW to assist the diesel-electric motors and optional Skysails.
When her first daughter was born, she and her husband decided that she would quit her job in publishing to stay home with the baby.
Her acclaim was so unanimous that in 2014 SNL aired a sketch about the Beygency, a shadowy group that punishes anyone who dared criticize her. The legislation was promoted by the Family Action Council of Tennessee, a conservative organization whose president once decried the American Psychiatry Association’s decision to remove homosexuality from its list of mental disorders.

Being capable to run on just electric, just diesel, or a combination of diesel and electric power, the captain can choose the best mode for the conditions. Since the energy crises of the 1970s, interest in this quiet and potentially renewable marine energy source has been increasing steadily again, especially as solar cells became available, for the first time making possible motorboats with an infinite range like sailboats. By 1889 the first 6 electric charter boats were working on the Thames and in the 1893 Chicago World Fair 55 carried more than a million passengers. Here the lake is considered so environmentally sensitive that steam and motor boats have been prohibited since 1909. Since then, electric power has been used almost exclusively for powering submarines underwater, although diesel was used for powering them on the surface until the development of diesel-electric transmission by the US Navy in 1928. By purchasing green electricity it is possible to operate electric boats using sustainable or renewable energy. Nonetheless, the heavier, rigid mono-crystalline types are more efficient in terms of energy output per square meter. Some electric power systems use the free-wheeling drive propeller to generate charge through the drive motor when sailing, but this system, including the design of the propeller and any gearing, cannot be optimised for both functions. It is important that the boat is big enough that the turbine can be mounted out of the way of all passengers and crew under all circumstances, including when alongside and when coming alongside a dock, a bank or a pier. It also ensures that they are not overcharged when nearing full charge and not overheated when a large charge current becomes available. They are heavy and bulky, but not much more so than the diesel engine, tanks and fittings that they may replace. This can be a traditional gear box, coaxial planetary gears or a transmission with belts or chains. Most available electric outboards are not as efficient as custom drives, but are optimised for their intended use, e.g. Electric propulsion is not suitable for prolonged cruising at full power although the power required to motor slowly in light airs and calm seas is small. The diesel engine is installed with the prime purpose of charging the battery banks, and the electric motor with that of propulsion.
The benefits to the global environment that are achieved by the use of electric propulsion are manifested during the working life of the boat, which can be many years. Jamie Campbell asserted that electric propulsion can no more be justified afloat than a Seagull outboard motor, proposing wooden sailing boats and rowing dinghies as "by far the most environmentally sensitive and renewable options for recreational boating". Desmond says that the US has a 98% recycling rate for lead acid batteries and that the battery and lead-smelting industries observe some of the tightest pollution control standards in the world. In the name of protecting the sincerely held beliefs of religious Americans, conservative lawmakers and lobbyists have introduced a spate of controversial religious-freedom legislation in recent months.
Electric Heavy duty outboard electric motors, electric marine motors, electric boat motors. It uses a working prototype to Solarboat Australia's leading electric boat specialist from 2001 to 2011.
But no info if the hybrid mode boats will be equipped with the Mercury Marine’s eco-screen or not.
Watch the beautiful natural world go by, listen to birdsong and the gentle lapping of water. Instead the Bayerische Seenschifffahrt company and its predecessors have operated a fleet of electric launches to provide a public passenger service on the lake. The efficiency of solar panels rapidly decreases when they are not pointed directly at the sun, so some way of tilting the arrays while under way is very advantageous.
It may be better locked off or feathered while the towed generator's more efficient turbine gathers energy. It is also important that the boat is big enough and stable enough that the top hamper created by the turbine on its pole or mast does not compromise its stability in a strong wind or gale. The advantage of both types is that while the speed can be controlled electronically, this is not a requirement. Because of the inevitable loss associated with gearing, many drives eliminate it by using slow high-torque motors. Regarding the second case, electric drives are ideally suited as they can be finely controlled and can provide substantial power for short periods of time. There is some reduction in efficiency if motoring for long distances as the diesel's power is converted first to electricity and then to motion, but there is a balancing saving every time the wind-, sail- and solar-charged batteries are used for manoeuvring and for short journeys without starting the diesel.
Solar powered boats started to become known around 1985 and in 1995 the first commercial solar passenger boats appeared. These benefits are also most directly felt in the sensitive and very beautiful environments in which such a boat is used. The answer: 47 percent of respondents said that either they would cover the expense by borrowing or selling something, or they would not be able to come up with the $400 at all.
But apparently Melissa McCarthy and Kristen Wiig aren’t the only ones fighting ghosts in 2016. The electric motor can be encapsulated into a pod with the propeller and fixed outside the hull (saildrive) or on an outboard fixture (outboard motor). They are quiet and they do not pollute the water or the air, so they do not scare away or harm fish, birds and other wildlife. There is the flexibility of being able to start the diesel as a pure generator whenever required. Care must be taken that there is no risk of the strong acid being spilled in the event of a capsize as this could be very dangerous. The advantages of these are the lack of commutators which can wear out or fail and the often lower currents allowing thinner cables; the disadvantages are the total reliance on the required electronic controllers and the usually high voltages which require a high standard of insulation.
Combined with modern waterproof battery packs, electric outboards are also ideal for yacht tenders and other inshore pleasure boats. The main losses are in weight and installation cost, but on the bigger cruising boats that may sit at anchor running large diesels for hours every day, these are not too big an issue, compared to the savings that can be made at other times. But with all that fresh air and exercise it’s not long before everyone is ready for a deep and refreshing sleep in one of the Mothership’s 4 cabins.
