SAILING YACHTS

Propulsion

Electric Engines

  • Electric Propulsion systems is the optimal green eco choice.
  • You have no fume, fuel, vibration and no disturbing background noise.
  • The carbon footprint of these yachts is minimal while operated.
  • They are highly reliable as they only have a few parts to maintain, compared to combustion engines with around 2000 parts. 
Propulsion

Hybrid Engines

  • The Hybrid Propulsion systems have solid performance Atlantic range. 
  • The components are chosen due to what needs the yacht and owners would have and gets fully integrated into the management and propulsion systems.
  • The sailing yachts can be equipped with advanced electric propulsion allowing power to be generated from the propeller rotation while the yacht is navigating under sail.
  •  This energy can be used to power the propulsion battery bank as well as the electronics on board. 
  • We would recommend solar panels and generators as backup. 

The first luxury electric catamaran: 

a Sunreef 50

Real data shows that we use 2-300 litres per week in charter.

Luxury boats with similar size in the same charter fleet doing the same routes, uses 8-900 litres per week.

Sunreef Tirilyacht

Tiril is generator and noise free at night, even with full air-conditioning and all house loads on!

The aim is to run the generator only 2-3 h per day in comparison to 24/7 on similar luxury boats.

The catamarans can be equipped with advanced electric propulsion allowing power to be generated from the propeller rotation while the yacht is navigating under sail. This energy can be used to power the propulsion battery bank as well as the electronics on board.

  • 2 x 35 kW IPM engines
  • 77kW lithium NCM batteries
  • 25kW DC generator (real)
  • 17kW AC generator (real this is max 13kW)
  • 9 kts top speed
  • 8 kts on 50 kW, 75 min on batteries or 3.5 h with generator
  • 7 kts on 30 kW, 2h on batteries or as long as there is diesel
  • 6 kts on 22 kW, 3h on batteries
  • 5 kts on 12 kW, 5h on batteries
Monohull

From the practical sailing yachts to the sporty performance yachts.

We offer integrated Electric and Hybrid systems on monohulls.

The instant feedback you get while sailing a monohull compared to a catamaran is for many an important reason for making the choice buying a monohull.

Bear in mind that in order to generate power from the propeller, hydrogeneration, the boat has to sail above 6 kn.

Inboarder

Many decides to go electric just to lower the noise level, others for environmental purposes. As we all know, oil doesn’t mix very well with water.

We can provide you an inboard engine that fits your purpose, from a power range of 10 kW up to 400 kW, liquid cooled or air cooled.

The video below was taken on one of our test drives, just to give you an idea on how the result could look like.

  • It’s a very affordable motor to use, it’s plug and play.
  • No fumes, no noise, no emissions
  • On-line software up-dates
  • The range depends on speed, weight, boat type and the conditions at sea
  • It’s the future of boating, the cutting-edge technology of electric boating

EPTechnologies can guide you through the process

EPT-Drive Control System for smaller boats

EPTechnologies has developed an intelligent HMI (Human Machine Interface) where we emphasise simple design and ease of use.
Of course, there is a lot going on behind the screen that is automated and only pops up when needed.

Tourist / Canal Boats

TOURIST / CANAL BOATS

A project we did turning a canal boat into a reliable electric canal boat.

With a wonderfully quiet motor you can cruise the canal and being environmentally friendly.
