About Our Technology

The Furyan F35 is the first 35ft sea going Eco Hybrid marine sports cruiser
with a serial electric hybrid propulsion system and integrated range extending generator.

97% reduction in CO2

The Furyan Cascade System with sterndrive features two electric motors run in series and a variable Hybrid power generator. The combined duty cycle of this system will have a 68% saving on fuel and CO2 (simulated sea conditions) and 100% clean CO2 when running on all electric.

The hull is manufactured using a natural lightweight fibre that can be recycled and has a low CO2 manufacturing ratio. 60% lower embodied energy than injection moulded GRP at the same stiffness and 40% lower weight. This material choice has a 77% reduction of CO2 over glass fibre construction, 90% cleaner than aluminium construction and is 97% cleaner than carbon fibre construction.

The stepped hull with wave piercing bow and deep V planning shows a 28% reduction in drag and a 4% gain in forward thrust compared to a conventional hull design (simulation data).
Electronic control systems minimise propellor slippage by up to 30% to maximise performance and extend the battery life of the hybrid boat.

    Frequently Asked Questions

    What are the main advantages of electric over diesel?

    According to market analysts the adoption of EV technology is for four main reasons, although in most articles the focus is generally on the environment and improving air quality.

    The main advantages of electric over diesel are

    1. Financial: an analysis of boat companies converted to hybrid show a 70% saving on diesel fuel costs and reduced maintenance costs giving a two year return on investment;
    2. Performance: hybrid/electric enable full power from stationery position and quieter running;
    3. Regulations: compliance with the increasing regulatory environment; and
    4. Environmental: boats converted to hybrid showed a 60% reduction on emissions reducing the harmful NOx, SOx and CO/CO2 gases.

    The harmful and polluting gases from the emissions of combustion engines include:

    Nitrogen oxide (NO) – harmful to humans and the planet, in high concentrations they are responsible for acid rain;

    Sulphur dioxide (from SOx) – a toxic gas directly harmful to human health;

    Carbon monoxide (CO) – is a gas poisonous to humans, CO2 is harmful in high doses;

    Hydrocarbon (HC) – pollute our water sources, stunt the growth of crops, endanger forests, and cause cancer in both humans and animals; and

    Particulate matter (PM) – high levels of PM are responsible for 7 million deaths globally and tens of thousands of deaths in the UK.

    So understandably switching away from fossil fuel powered combustion engines makes sense for us and the planet. 

    How far might I expect to travel in an electric hybrid boat?

    How far you can travel will depend on a number of factors, including the weather and the tide, but for example in eco mode of the Furyan F35 you can travel for over 12 hours at a speed of 12 knots (approximately 150 nautical miles) before needing to top up the batteries or use the range extender.

    How will I recharge my electric or hybrid boat?

    At Furyan we can offer three methods of recharging:

    The first is fast charging at the fuelling station of a marina.  For the Furyan F35 recharging could be done from fully discharged to fully charged in under one hour;

    The second is pontoon berth charging using a DC wall box and recharging from fully discharged to fully charged could be done overnight, in approximately 10 hours; and

    The third option is portable charging that can connect to almost any electrical supply and can provide a top-up charge of up to 22kW or a trickle charge over 24 hours depending on the electrical supply.

    If you're not in a marina with an electric supply, how do you recharge your boats electric batteries?

    The Furyan F35 design features a range extending generator which can be used to top up the batteries whilst at sea or away from an electrical power source.

    The range extending generator can directly drive the boat back to port at a speed of up to 12 knots.

    What happens when the battery pack is fully discharged or fails?

    Getting stranded at sea is a potential problem for battery powered boats if the batteries are fully discharged or the battery fails. 

    The design of Furyan F35 overcomes this challenge by having four battery packs each independent of each other so that if one fails the other battery packs can still drive the two motors. 

    In the unlikely event that one motor fails, the other motor will still be able to drive the sterndrive. 

    In a disaster scenario, where all four batteries fail and the two motors fail, then the range extending generator can directly drive the boat back to port at a speed of up to 12 knots.

    What is the cost of a Furyan Eco Hybrid electric boat compared with a fossil fuelled alternative?

    Hybrid technology does not come cheap as everyone will know from the automotive market, where battery powered cars carry a significant premium. 
    At Furyan we are adopting design and production principles from the leading and most efficient automotive manufacturers and applying them to the marine sector.  This is helping us reduce the cost of the Furyan F35 so that we are able to offer it for sale at a guide price similar to fossil fuelled powered equivalents.

    How does the running costs of an electric boat compare to diesel or petrol powered boats of similar size and spec?

    A study by analysts reviewed data of boat companies converted to hybrid that showed a 70% saving on diesel fuel costs and reduced maintenance costs giving a two year return on investment.

    What makes the Furyan F35 an environmentally friendly alternative when compared with other boats?

    There are four main areas where the Furyan F35 technology makes it a more environmentally friendly alternative when compared to other boats:

    (1) the choice of material and production process of the hull: the material used in the Furyan hull has 77% lower CO2 compared with glass fibre and 97% CO2 lower than carbon fibre.  The production process uses 85% less water and 70% less energy than carbon fibre.

    (2) the design of the hull with 28% less drag makes it more efficient: Furyan have used world leading consultants in computational fluid dynamics (CFD), hydrodynamic consultants and finite element analysis (FEA) to optimise the design of the hull.

    (3) the cascade propulsion system: the motors run as separate motors or linked as the power is required to match the propeller load curve to the linear power line of the electric motor. The motor link is through a seamless dog-clutch engagement system, so each motor runs at maximum efficiency. 

    (4) the electronic controls minimising propellor slippage: the electronic control and display system with intelligent software and touch screen minimises waste by matching the power output to that required, minimising propeller slippage which can account for up to a 30% loss of energy.

    What is the difference between a Furyan hull and a glass reinforced polymer or carbon fibre alternative ?

    The Furyan hull will be manufactured using a natural lightweight fibre that can be recycled and has a low CO2 manufacturing ratio.  In its production it uses 85% less water and 70% less energy than carbon fibre.  This material choice has a 77% reduction of CO2 over glass fibre construction, 90% cleaner than aluminium and 97% cleaner than carbon fibre construction.
    This natural material is CO2 neutral over its life cycle and has 60% lower embodied energy than injection moulded Polypropylene at the same stiffness and is 40% lighter in weight.

    Can the Furyan Cascade propulsion system be used in other boats?

    The Furyan cascade propulsion system is a hybrid system and this hybrid system can be configured for other vessels including other motor cruisers, passenger or freight ferries and even in-shore fishing fleets. 

    The Furyan cascade propulsion system can also be configured to be a pure electric system in applications that do not require a range extender as a backup.
