RS Electric Boats, the brand-new sister company to RS Sailing, this week launches the Pulse 58 - its electric RIB. Unveiled at Boot Dusseldorf, the Pulse58 is the product of two years of development and is ground-breaking as the first-ever production RIB with a fully integrated electric drive.

The marine industry trails behind car manufacturers in terms of engine emissions and a defined future for alternative energy. Evolving environmental attitudes and imminent changes to law around the world are driving demand for a different approach to boating that removes the negative impact of a fossil fuel burning motor.

With 25 years of design and build experience in zero emissions boating, RS’ Pulse58 will blend proven automotive electronic technology and an extremely efficient electric drive optimised hull form, with the highest level of sustainable construction of any boat in its sector.

Project managed by the award-winning RS development team alongside key industry experts, Pulse58 uses marinized electronic components already well proven in automotive use. A 57Kwh battery bank stored in a purpose designed underfloor structural case delivers up to 104v to the ground-breaking RAD drive propulsion unit. RAD drive is a unique and integral retractable drive unit that belt feeds power from the twin motors to a hub-less drive unit. The electronic management system controls all aspects of the drive, motor control and battery conditioning and also controls the electric drive tilt mechanism that lifts the RAD drive into the transom in shallow water.

Pulse58’s hull design has been purposely designed for its electric drive. The tunnel hull form and long waterline length give decreased low speed drag that suits the instant torque of electric power, while providing a stable and maneuverable platform at speed. The battery bank deep in the hull lowers the centre of gravity increasing comfort. Hypalon tubes and an integral cockpit non-slip floor combine to give a high quality and long-lasting finish. The acclaimed Raymarine Axiom 7” touch screen display is standard fit on the console. Alongside all the advanced plotting and navigation features, Axiom also displays the power reserve, instant range and battery data delivered by the RADLink transmitter. RADLink then broadcasts by Bluetooth and 4G to its mobile app to give remote charge data along with revolutionary geofencing capabilities to control security and safe use.

Pulse58’s sustainable construction comprises of Bio-based infused epoxy resin, recycled PET core material and naturally sourced basalt and flax fibres. These fibres are incredibly strong and energy absorbing. Experience gained in the sustainable construction of the successful RS Aero and RS21 sailboats has enabled RS to bring to market the most sustainable laminate of any RIB in the sector. This innovative laminate is lightweight and long lasting in even the most extreme environments.

Pulse58 debuts at Boot Dusseldorf on Saturday 18 January - 16:30 (CET) - Hall 15 – Stand E24.

About Electric outboard engines

The direct-drive component in electric outboard engines means that the electric motors are incredibly efficient compared to conventional marine combustion motors, operating with considerably higher torque whilst using less power.

Without any need for gears, cooling systems and moving parts the motors are maintenance free, highly efficient and economic to run.

As a result, electric boat engines are becoming more popular on Irish waters as the world transitions from fossil fuels to green energy.

To date, popular electric engine sizes have been trolling engines typically used by fishermen on lakes.

These marine engines are available in models that can be used in fresh water and sea water, for your boat or kayak.

Electric motors are Ideal for fishermen because they are quiet and create little in the way of disturbance 

Popular electric trolling models range from 30lb thrust to 55lb thrust in a range of shaft lengths.

But use is becoming broader now in 2021 and electric outboard engines are being used on small runabouts and RIBS where electric outboard engine sizes are getting bigger.

Outboard electric engines are economical and environmentally friendly. Battery technology is also improving at a rapid rate meaning they are becoming smaller and lighter and run for longer.

Built in hydro-generation provides alternative recharging options whilst under sail are also options meaning the electric outboard now has a home on the stern on small yachts and dayboats too.

As far back as 2014, Torqeedo owner Jack O'Keefe from Cork Harbour told Afloat readers of his sailing adventures in a Drascombe Coaster dinghy and how after swapping from a petrol version the rewards from his new electric outboard engine are less noise, no smells, more stowage, better sailing performance and a motor that can be started by a small child. But it's still not silent, there's a whine he says here 

Popular brands in Ireland are Torqeedo, ePropulsion, Pulsar and Minn Kota but there are more arriving all the time as the technology advances
