HISTORY OF ELECTRIC BOATS

 

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. Electric boats were very popular from the 1880s until the 1920s, when the internal combustion engine took dominance. 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. The first practical solar boat was probably constructed in 1975 in England.

 

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 was successfully demonstrated to Emperor Nicholas I of Russia on the Neva River.

 

It took more than 30 years of battery and motor development before they began to be deployed in any numbers. In 1886 an electric boat crossed the English Channel both ways in 8 hours. 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.

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. 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).

 

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. 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. It was 52 feet (16 m) long and could take 75 passengers, and is now being restored.

 

In a few situations, the use of electric boats has persisted from the early 20th century to the present day. One of these is on the Königssee lake, near Berchtesgaden in south-eastern Germany. Here the lake is considered so environmentally sensitive that steam and motor boats have been prohibited since 1909. Instead the Bayerische Seenschifffahrt company and its predecessors have operated a fleet of electric launches to provide a public passenger service on the lake.

 

In the US, the Electric Boat Company was founded in 1899 and built the first submarine purchased by the U.S. Navy in 1900. 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. The Electric Boat Company eventually became General Dynamics Corporation in 1952.

 

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 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 maneuverability.

 

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. Duffy Boats has produced over 10,000 electric powered boats to date and is producing well over 300 per year today. It wasn't until the 1980s that the Electric Boat Association was formed and solar powered boats started to emerge.

Thought to be the world's most advanced solar powered ship, development of the Elizabeth Swan active SWASH hull platform is underway in 1/20th scale for tank and open water tests, the most important part of which is harvesting energy from nature effectively to provide speeds of 7 knots for cruising and 10+ knots for 10 hour+ dashes to specific locations. The above picture shows the model's solar wings above a supporting frame in wood (aluminium on the final models) and the jig (in white) that is used to assemble each model - three in all.

EB COMPONENTS

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.

 

 

CHARGER

Electric energy has to be obtained for the battery bank from some source.

A mains charger allows the boat to be charged from shore-side power when available. Shore-based power stations are subject to much stricter environmental controls than the average marine diesel or outboard motor. By purchasing green electricity it is possible to operate electric boats using sustainable or renewable energy.

 

Solar panels can be built into the boat in reasonable areas in the deck, cabin roof or as awnings. 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. Nonetheless, the heavier, rigid mono-crystalline types are more efficient in terms of energy output per square meter. 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.

 

Towed generators are common on long-distance cruising yachts and can generate a lot of power when travelling under sail. 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). 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 may be better locked off or feathered while the towed generator's more efficient turbine gathers energy.

 

Wind turbines are common on cruising yachts and can be very well suited to electric boats. There are safety considerations regarding the spinning blades, especially in a strong wind. 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 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. Large enough wind generators could produce a completely wind-powered electric boat. No such boats are yet known although a few mechanical wind turbine powered boats exist.

 

If the boat has an internal combustion engine anyway, then its alternator will provide significant charge when it is running. 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.
In all cases, a charge regulator is needed. This ensures that the batteries are charged at the maximum rate that they safely can stand when the power is available. It also ensures that they are not overcharged when nearing full charge and not overheated when a large charge current becomes available.

 

 

BATTERY BANK

There have been significant technical advances in battery technology in recent years, and more are to be expected in the future.

 

Lead-acid batteries may still be a viable option for cheap builds. Deep-cycle, 'traction' batteries are the obvious choice. They are heavy and bulky, but not much more so than the diesel engine, tanks and fittings that they may replace. They need to be securely mounted, low down and centrally situated in the boat. It is essential that they cannot move around under any circumstances. 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. Venting of explosive hydrogen and oxygen gases is also necessary. Typical lead-acid batteries must be kept topped-up with distilled water.

 

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. These batteries require minimal maintenance, as they cannot and usually do not need to be refilled with water.

 

Nickel metal hydride, lithium-ion and other solid-state batteries are becoming available, but are still expensive. These are the kind of batteries currently common in rechargeable hand tools like drills and screwdrivers, but they are relatively new to this environment. They require different charge controllers to those that suit lead-acid types.

 

Fuel cells or flow batteries may provide significant advantages in years to come. Today (2013) however they are still expensive and require specialist equipment and knowledge.

 

In conventional electric boats the size of the battery bank determines the range of the boat under electric power alone. The speed that the boat is motored at also affects the range - a lower speed can make a big difference to the energy required to move a hull. Other factors that affect range include sea-state, windage and any charge that can be generated while under way, for example by solar panels in full sun. A wind turbine in a good following wind will help.

 

 

SPEED CONTROL

To make the boat usable and maneuverable, a simple-to-operate forward/stop/backwards speed controller is needed. This must be efficient—i.e. it must not get hot and waste energy at any speed—and it must be able to stand the full current that could conceivably flow under any full-load condition. One of the most common types of speed controllers uses pulse-width modulation (PWM). PWM controllers send high frequency pulses of power to the motor(s). As more power is needed the pulses become longer in duration.

 

 

ELECTRIC MOTOR

A wide variety of electric motor technologies are in use. Traditional field-wound DC motors were and still are used. Today many boats use lightweight permanent magnet DC motors. The advantage of both types is that while the speed can be controlled electronically, this is not a requirement. Some boats use AC motors or permanent magnet brushless motors. 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.

 

Traditional boats use an inboard motor powering a propeller though a propeller shaft complete with bearings and seals. Often a gear reduction is incorporated in order to be able to use a larger more efficient propeller. This can be a traditional gear box, coaxial planetary gears or a transmission with belts or chains. Because of the inevitable loss associated with gearing, many drives eliminate it by using slow high-torque motors. 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).

 

 

TYPES of ELECTRIC BOAT

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. See the Mary Gordon Electric Boat for example.

 

 

CANAL, RIVER and LAKE BOATING 

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 drives are also available as auxiliary propulsion for sailing yachts on inland waters.

Electric outboards and trolling motors have been available for some years at prices from about $100 (US) up to several thousand. These require external batteries in the bottom of the boat, but are otherwise practical one-piece items. Most available electric outboards are not as efficient as custom drives, but are optimised for their intended use, e.g. for inland waterway fishermen. 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. Combined with modern waterproof battery packs, electric outboards are also ideal for yacht tenders and other inshore pleasure boats.

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. 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. 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. 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.

 

 

DIESEL-ELECTRIC HYBRID 

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. 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 diesel engine is installed with the prime purpose of charging the battery banks, and the electric motor with that of propulsion. 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. There is the flexibility of being able to start the diesel as a pure generator whenever required. 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.

 

 

 

 

SOLAR POWER

A boat propelled by direct solar energy is a marine solar vehicle. 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. Power levels are usually on the order of a few hundred watts to a few kilowatts. Solar powered boats started to become known around 1985 and in 1995 the first commercial solar passenger boats appeared. Solar powered boats have been used successfully at sea. The first crossing of the Atlantic Ocean was achieved in the winter of 2006/2007 by the solar catamaran Sun21.

 

 

POLLUTION and EMBODIED ENERGY

EMBODIED ENERGY

All the component parts of any boat have to be manufactured and will eventually have to be disposed of. Some pollution and use of other energy sources are inevitable during these stages of the boat's life and electric boats are no exception. 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. These benefits are also most directly felt in the sensitive and very beautiful environments in which such a boat is used.

The May 2010 edition of Classic Boat magazine carried a pro and con article entitled Electric debate. Jamie Campbell argued against electric boating on four main counts, which were rebuffed by Kevin Desmond and Ian Rutter of the Electric Boat Association. 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".

Electricity production

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. 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. Rutter notes that electric boats tend to recharge overnight, using 'base load'.

Efficiency

While there are losses in the charge/discharge cycle and in the conversion of electricity to motive power, Rutter points out that most electric boats need only about 1.5 kW or 2 hp to cruise at 5 mph, a common maximum river speed and that a 30 hp petrol or diesel engine producing only 2 hp is considerably more inefficient. 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.

 

Pollution

 

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. Rutter points to the "very nasty cocktail of pollutants" that come out of a diesel wet exhaust in normal use.

 

 

BATTERY MANUFACTURE

Campbell mentions "all manner of noxious chemicals ... involved in battery manufacture", but Rutter describes them as being "lead and sulphuric acid with a few extra trace metals in a modest plastic box" with a potential lifetime of 10–12 years. 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.

 

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. It is claimed that a typical recharge after a day's cruising costs £1.50, without the use of solar or wind power.


SOLAR SHIPS

In 2010, the Tûranor PlanetSolar, a 35 metre long, 26 metre wide catamaran yacht powered by 537 square metres of solar panels, was unveiled. 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. It is so far the largest solar-powered boat ever built.

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. 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.

THE WORLD RECORD TO BEAT

 

Truly an amazing achievement. The Tûranor PlanetSolar ([TPS] from Tolkien) pictured below was launched in March 2010 in Kiel, Germany. The electric circumnavigation took roughly 585 days to complete at an average speed of around 2.63 knots, to set the world's first solar powered record on the 4th of May 2012. For a pioneering first that is quite spectacular running and all of us at Max Energy offer our most heartfelt congratulations to Raphael Domjan and Immo Stroeher. The TPS has proved solar power is viable for blue water transport. The route that this magnificent boat has plied is virtually the same route proposed by the designer of the first Solar Navigator, when he exhibited his SWATH world record contender in December of 1995 at the Earls Court boat show. 

 

So what's next? Well, believe it or not, an autonomous circumnavigation is a looming possibility. Yes, that's right - not a crew member in sight (except as observers) at the helm, the Elizabeth Swan will be able to steer herself around the world in all weathers. The Cleaner Ocean Foundation are insisting on qualified crew in any event, since unmanned boats are a relatively recent development, meaning that it is even more important that the crew know what the vessel is capable of when it comes to writing a Road Test Report.

 

Solar boats tick a number of boxes for the United Nations in terms of climate change and marine conservation, where the elimination of conventional bunker fuels would be a major step forward in fighting acid oceans. These are known as Sustainability Development Goals or SDGs.

FUTURE WORLD CONTENDERS

 

Electric boats have been plying waterways in Europe since around 1890.  In 1905 the 'Victory' was launched on the River Thames, at that time the largest electric boat in the world.  She was 93 feet long and wood built.  The Victory could carry 350 passengers.  Before the internal combustion engine became popular electric boating rivaled steam and horse drawn barges.  Battery powered pleasure-boats were charged-up by steam powered generators and overhead cables.  In England canals provided a comprehensive network for working narrow-boats carrying cargo. After 1905 the internal combustion engine became popular, ironically, due the the invention of the electric starter motor.
