Customer experiences

  • Very good, nice specialist in electric boating. We had our antique sloop converted from diesel to electric. Still looks like 1930s riveted metal boat but now completely silent and hopefully much more reliable! Well advised and neatly executed.

    Egbert Hendriks | Leiden

  • This company really cares about the customer and they work excellently with Green Marine (the supplier of the electro motor and accessories). Even outside my warranty time, my query was thoroughly investigated by both parties and resolved free of charge. So these people stand 100% behind their product. I recommend e-yard and Green Marine to everyone.

    Bryan Mendean | Amsterdam

  • We are very satisfied with E-Werf. They repaired our electric sloop there, after we already had several repairs done at others. This time we immediately felt: here they know what they are talking about. Boat and motor back in top condition. And, importantly, they are easy to reach and always return phone calls. Nice people too, by the way.

    Duco Zoomer | Amsterdam

  • Agreed on an optimal electric solution for my "antique" Petersson (from 1927). 7.5 Kwh Waterworld with lithium battery pack (11 Kwh) enough for a full sailing day. Terrific, committed, enthusiastic for electrifying my boat. Highly recommended. Would knock on their door again in a heartbeat.

    Hank Smits | Amsterdam

  • My boat has been beautifully converted! From smelly noisy diesel to quiet electric motor. A pleasure to sail. Conversion neatly within quotation and planning. Very nice and highly skilled people.

    Hans Frings | Arnhem

  • At E yard I had my classic motor vessel (Pettersson 10.7 metres) electrified this winter. VW Marine 4 cylinder diesel out (including the 2 diesel tanks) and a 48V electric Green Marine 18 Kw in. With 2 heavy ecolithium (26Kw) battery packs. These guys know what they are talking about. High-tech work. But above all with great respect for a classic 1928 ship. Ship sails great and silently. Transparent in costs and approach right from the start. Highly recommended.

    Huibert Jongenburger | Amsterdam

  • Top service from the manner of E-yard. As there was a place free, I could go straight away and my sloop was electric within a few days. And how!!!? What a relief!

    Huub van Zwieten | Amsterdam

  • Good reliable partner to have your boat converted to electric with. I simply cannot say more.

    Inge Voorhans | Haarlem

  • 5 stars

    Jan Willem Vaartjes

  • The best products and services come from inspired individuals and companies. E-Werf is one such inspired company with committed, inspired staff. Customer-focused, hands-on, practical and budget-fixed. In three months, from a lifeboat suspended from a Scottish freighter, to a stylish sloop that now glides silently across the Frisian waters. I really enjoyed the process with E-Werf. And I am very happy with the sloop.

    Jan-Arie Dekker | Langelille (FR)

  • Very passionate skilled people at E-Werf. Good technical know-how, first maintained and updated my sloop very well. After a while also super helped with the sale of the Sloop. If I ever have anything with an electric sloop again I will definitely go to this yard again

    Jean-Pierre Berentsen | Amsterdam

  • As we will soon only be allowed to sail with electric motors, I came to E-Werf for the renovation of my sloop. The pragmatic approach and helpfulness really appealed to me, so the electric motor was installed at short notice in late spring and I could still fully enjoy my new acquisition. E-Werf gives excellent advice on options, type of motors, battery capacity. Aftercare and maintenance is of an exceptional level. Meanwhile, the renovation has also been carried out to perfection. I am extremely satisfied.

    Ludo Menso | Amsterdam

  • Olivier and the team at E-Werf are fantastic. Not only did they help me find a suitable boat, they also gave very good advice on the most suitable battery to suit my needs and all kinds of other things I didn't know about as a new electric boat owner. Even after the sale there is easy and good contact with E-Werf.

    Maaike van der Windt | Amsterdam

  • In autumn 2021, I asked E yard to fit an electric drive system in my still relatively young Waterdream 740. We quickly came to an outline agreement and then a detailed estimate of costs, materials, and time schedule was drawn up. Olivier and Jaap are very knowledgeable about the technology and the final assembly went quickly, efficiently and without many problems. All estimates of time and costs were realised exactly. I have now been sailing electric in Amsterdam for a few months without any problems. If I have any questions, I can always contact Olivier and Jaap immediately; so far, the few issues could be solved immediately online. All in all, I have experienced E-werf as very knowledgeable, 100% reliable, and extremely pleasant to deal with! Paul Kenninck

    Paul Kenninck | Amsterdam

  • Great service and perfectly delivered

    Rene Louis

  • Asloop 650 converted from diesel to electric this summer and had some other minor work done. The team has good knowledge of different systems, love for the job and it was pleasant working together

    Sander van Riel | Amsterdam

  • Very knowledgeable and helped quickly with a replacement of my battery pack. Switched to lithium batteries from e-yard. Very satisfied. Noiseless and worry-free sailing. Excellent and quick communication with the staff of e-yard. I enjoy coming there. I have been sailing electric for over 15 years, with e-yard the best experience so far.

    Simon B | Amsterdam

  • How does electric boat conversion work

    Converting your boat is a project we would like to involve you in

    01.

    Introduction

    First of all, we will make a full analysis of your boat and then give you full advice on the desirable and possible activities, possibly in a multi-phase plan. After we have drawn up a plan together with you, you will receive a quotation from us detailing exactly what we will do. All according to the latest safety and quality standards.

    02.

    Planning and start of the project

    Here, the boat is delivered to us and a further inspection in connection with the agreed activities follows. Any "surprises" are discussed with you even before significant costs are incurred; if necessary, this can lead to adjustment of the agreement.

    03.

    Old out

    This involves removing the engine, and any drive components such as e.g. propeller and propeller shaft (we pay attention to reuse and residual value) as well as control electronics and possibly parts of the interior.

    04.

    New in

    This involves assembling the new driveline on site. Any support is remanufactured, in-house. Adjustment on the propeller shaft is realised. Control electronics (largely supplied with the engine will be reinstalled.

    05.

    Test & transfer

    After the intended final stage has been reached, an extensive testing phase takes place after which our team may recommend additional work. However, we try to avoid the latter as much as possible to offer you the best possible transparency. Once the test procedure has been successfully completed, the boat is ready for delivery and you can go electric. For us, this was a revelation; we are sure you will feel the same way!

    06.

    Sailing and service

    After a few weeks, you won't want anything else and you'll be completely used to the gentle lapping of the waves against your boat. We would then like to give the boat a final check and tighten everything up where necessary. If you have any other points of concern, we can also look at these straight away.

    • E-WERF is bringing the Helios Omega 7.2 to the Netherlands

      E-WERF is bringing the Helios Omega 7.2 to the Netherlands

      We are proud to announce that E-WERF has become the official importer and dealer for Helios Marine in the Netherlands. This marks a further expansion of our activities. In addition to electrifying existing boats, we can now also offer our customers a completely new vessel, designed from the drawing board as an electric boat. The first Helios Omega 7.2 has now been ordered and will make its Dutch debut at the upcoming HISWA te Water. Visitors will not only have the opportunity to view the boat in detail, but also to take it for a test sail themselves. The Helios Omega 7.2 is a 7.2-metre day cruiser developed entirely as an electric vessel. Unlike many electric boats, which are derived from an existing fuel-powered model, the Omega has been designed from the ground up as an electric vessel. This is evident in every aspect: the hull shape, the weight distribution, the efficiency and the integration of all systems. The Omega is available with various battery capacities and power outputs, features integrated solar panels and is equipped with Helios Marine Link. This smart platform allows real-time monitoring of, amongst other things, battery status, energy consumption, charging status and various on-board systems, both on board and remotely. For E-WERF, Helios Marine aligns seamlessly with our vision. We believe that electric boating goes beyond just an electric motor. The combination of an efficient hull, high-quality battery technology, smart software and a fully integrated design ensures a boating experience that stands out in terms of comfort, performance and ease of use. At HISWA te Water, we’d be delighted to tell you all about the Helios Omega 7.2. Would you like to experience for yourself how this electric day cruiser handles? Then you’re very welcome to come along for a test sail.

    • Venice Boat Show

      Venice Boat Show

      E-WERF visits the Venice Boat Show The whole E-WERF team travelled to Venice for an inspiring visit to the Salone Nautico. It was a special trip, partly because we collaborate with a boat builder from this region. We designed the complete electric propulsion system for this shipyard and supplied it as a plug-and-play solution. During the exhibition, we test-sailed a large number of electric boats and propulsion systems. What immediately struck us was how rapidly developments are currently unfolding. Electric boating is no longer limited to calm inland waters. Increasingly mature, reliable and practical solutions are also becoming available for coastal waters, high-speed applications and high-voltage systems. It was also clear that sustainability is playing an ever-greater role within the water sports sector. The proportion of electric and hybrid boats at the exhibition is growing every year. This year, too, there were more electric boats moored at the jetties than at the previous edition, and a special exhibition area had been set up for electric and sustainable boating. The absolute highlight of our visit was the e-regatta. Together with all the electric boats at the show, we sailed in a parade along the Grand Canal, right through the heart of Venice. This attracted a lot of attention along the quays, and it was remarkable to see how much interest there is in emission-free boating. For us, it was a unique experience and a wonderful showcase for the future of sustainable boating. For E-WERF, the visit to Venice was not only educational and inspiring, but also a confirmation that electric boating is gaining momentum internationally. The technology is improving, the applications are broadening and acceptance is growing. It is encouraging to see that the developments we work on every day are now becoming visible on the water worldwide.

      E-WERF Amsterdam | your partner for electrical marine installations in commercial shipping

      Electric marine installations in commercial shipping

      E-WERF is a shipyard on Amsterdam's Nieuwe Meer lake, specialising in electric and hybrid drives. Since our start in 2016, we have electrified over four hundred boats in the private segment. We have also been active in commercial shipping for some time now, where we have also been carrying out projects according to ES-TRIN guidelines for about two years.

      Our work includes:

      • maintenance and servicing of electrical installations;
      • troubleshooting;
      • Conversion from diesel to electric, including guidance from design to implementation;
      • completion of airframes;
      • development and construction of new ships.

      Maintenance and servicing of electrical installations

      Proper maintenance prevents breakdowns. At E-WERF, we carry out thorough servicing of electric and hybrid installations for commercial vessels. We check systems for wear and tear, replace components where necessary and keep installations in top condition. Through regular inspection, we extend the life of your installation and prevent costly downtime. Everything is done quickly, professionally and to the highest quality standards. We can also carry out painting and carpentry work on your vessel.

      Troubleshooting, on site or at our yard

      A breakdown can happen unexpectedly. We make sure you can sail again quickly. In the Amsterdam region, we always try to solve a breakdown on-site as quickly as possible. Thanks to remote monitoring, we can even identify and supervise some breakdowns remotely. Our goal: minimum downtime, maximum reliability.

      Conversion from diesel to electric (according to ES-TRIN)

      E-WERF specialises in making commercial vessels fully electric. We take care of the entire process: from technical design to installation, testing and certification. Each installation is custom-designed, tailored to the vessel's usage profile and always according to ES-TRIN standards. You will receive expert guidance and clear communication at every stage of the project. We deliver proven quality, with short lead times and full project control.

      New construction and completion of airframes

      Whether it is the finishing of a hull or the construction of a new electric ship, we deliver customised work with an eye for detail. We build ships completely in-house, from installation work to carpentry finishing. For new construction projects, we integrate electrical systems from the design phase, tailored to your requirements and sailing goals. We ensure that everything, from power supply to on-board equipment, works seamlessly together. Executed efficiently, without compromising on craftsmanship or reliability.

      At our yard on Nieuwe Meer, we can hoist ships of up to six tonnes and ramp them up to 3.5 metres wide. The maximum length at this location is 14 metres. For larger ships, we have fall-back locations in the area and can also work on site at other shipyards. We notice that many shipowners already know us from the private market, but do not yet know that we also work for commercial shipping. We therefore like to make ourselves known to you. You are more than welcome to visit us at the shipyard, but if you wish, we are also happy to visit you to introduce ourselves.

      We hope to speak to you soon. Olivier Venema | E-WERF Amsterdam

      Electric boating in Amsterdam

      Electric boating in Amsterdam: obligation, costs and charging options

      In Amsterdam, interest in electric boating is growing rapidly. The city is investing heavily in a cleaner and quieter living environment and is therefore making clear choices for the future. Many water sports enthusiasts are wondering what this means in concrete terms: from when will electric boating become compulsory, in which zones will the rules apply, what will a conversion to electric cost and where will you be able to recharge? In this article, we clearly list the main points and help you on your way to emission-free boating.

      When will electric boating become mandatory in Amsterdam?

      Amsterdam will introduce an emission-free zone for pleasure boats in the city centre from 1 April 2025. This means that boats running on combustion engines will then no longer be welcome within the designated area. Only boats that are fully electric, use hydrogen or run on muscle power will then be allowed to enter the city centre. Most of the city centre, including the waters within the Singelgracht, is expected to fall within this zone.

      For owners who still have an older vignette, there is a limited transition period. However, that too will expire soon. Those who want to continue sailing in the centre of Amsterdam would be wise to take timely action. Moreover, around 2030, the emission-free obligation will extend to the entire Amsterdam metropolitan area. This will make electric boating the standard for all types of vessels, from small sloops and sailing yachts to larger motorboats and tour boats.

      For many boat owners, this means that opting for electric boating is not only sustainable and comfortable, but also necessary to maintain access to Amsterdam's waters in the future.

      What does converting your boat to electric cost?

      The cost of a conversion varies greatly depending on the type of boat, the desired range and the configuration of engine and battery. A smaller sloop of six to eight metres can in many cases be converted for sums starting at around ten to eighteen thousand euros. Larger sloops of eight to ten metres often fall into the fifteen to twenty-five thousand euro category.

      Sailing yachts between six and 12 metres usually have a wider range, often between 12 and 30 thousand euros, depending on the space available and the desired motoring time. For motor boats of ten to twelve metres, the investment is higher; amounts between twenty-five and forty-five thousand euros are common. Larger vessels, such as canal boats, require heavier drivelines and larger battery packs. For these, costs often start at around forty thousand euros and can rise well above one hundred thousand euros.

      The final price is mainly determined by the size of the battery pack, the engine needed, the existing condition of the vessel and any work on the technology on board. Customisation plays a major role here. Consider adjusting the propeller shaft, integrating a new 48V system or replacing a lead-acid household bank with lithium. Although an electric conversion is an investment, you benefit from much lower running costs, silence on board and a future-proof installation.

      Those who want to know what is possible for their boat can have a technical assessment carried out. An inspection gives quick insight into costs, parts needed and the most suitable configuration. Rather convert it yourself? Take a look at Boatbuilding.co.uk for the options.

      You can also our configurator use to estimate the cost of a conversion to an electric drive.

      Where can you charge electrically in Amsterdam?

      Amsterdam is working hard to expand its charging infrastructure for electric boating. Currently, charging points are available in marinas and at several locations along the water, and this number is growing rapidly. In the coming years, hundreds of new charging points will be installed, ranging from standard shore power to special charging columns for maritime use.

      See the municipality's website for an up-to-date overview.

      Many marinas already have reliable shore power facilities. For many boat owners with removable batteries, it is even possible to charge at home with a suitable charger on a regular socket. This is especially true for smaller sloops and sailboats sailing with a relatively compact battery pack.

      Larger systems require heavier charging points. These are increasingly becoming available at ports responding to the demand for electric boating. New charging facilities are also being developed at strategic locations along canals and shipping routes. As a result, you can increasingly count on a stable network of charging points in the city.

      Those wishing to go electric would do well to check what options are available at their own port or berth. Many ports are currently expanding their facilities, often in cooperation with marine installers. Electric charging is expected to become as natural as charging an electric car.

      Ready to make the switch to electric boating in Amsterdam?

      Electric boating is fast becoming the new norm in Amsterdam. The combination of regulations, better technology, lower maintenance costs and more charging options makes the switch increasingly attractive. For those who want to keep an existing boat, conversion offers a sustainable and future-proof solution. A first step is always good technical advice and a clear quotation, so you know exactly what to expect.

      Electric boating means quiet trips through the city, no emissions, less maintenance and the certainty of continued access to Amsterdam's waters. Those who start orientating early will benefit from the best side of electric boating.
