FOR THOSE LOOKING FOR A MORE ECO-FRIENDLY TENDER, PETER MINDER REMINDS US THAT THERE IS NOW NO NEED TO COMPROMISE

For a long time, electric boats have had the aftertaste of slow, sluggish, complicated and impractical. But today, modern boats that have been consistently developed and designed with electric propulsion in mind have a performance comparable to that of combustion engines. The great and continuing progress in battery technology has also resulted in ranges that are sufficient for most of the usual applications.

And with regard to safety, the batteries, which are now specialised for marine applications, convince with all kinds of safety features.

Many years ago, ‘designboats switzerland ltd’ took a pioneering role in the development of modern, ultra-light sports boats and tenders. These boats, known under the label ‘tender by designboats’ and awarded with various design awards, have quickly found a large and loyal following and are in use on many inland and coastal areas. In the recent past, an ever-increasing proportion of the electric versions available for almost all types of boats has been ordered.

In addition to the models of the ‘tender by designboats’ (www.designboats.ch), their sister company ‘compositeworx’ (www.compositeworx.ch) has been offering custom-made boats based on their many years of experience and comprehensive know-how for some time now.

The focus is mainly on custom-made individual products as exclusive dayboats or as tender for a luxury yacht. These boats are developed and manufactured according to the individual specifications of the yacht owner or his designer. The infrastructure is ideal for boats up to 12m in length - but projects up to 15m in length have also been realised. Whether diesel propulsion or electric drive is solely the decision of the customer - the company compositeworx masters both tasks and knows exactly what is important for which drive variant.

Especially in the megayacht sector, the use of an electric drive is predestined for the tenders. In most cases, these tenders only have to cover short distances. In between the missions they are stored on board the mother yacht - where an appropriate charging infrastructure is available. On the other hand, the almost silent and above all exhaust-free and vibration-free drives spoil the guests with a driving experience in a class of its own.

Electric megayacht tenders are thus suitable for everyday use and comfortable. As the electric boats are also almost completely maintenance-free, they are also convincing in terms of maintenance and operating costs.

With the usual warranty periods for the batteries (up to ten years) and the extremely low maintenance and operating costs of an electric boat, the additional one-time extra costs can be recouped after only a short period of use.

However, experience has shown that for an efficient and smoothly functioning electric boat/tender, this boat must be designed from the ground up to meet the special requirements of a battery-powered electric boat. The mere conversion of an existing boat concept into an electric version will most likely not achieve the desired result and thus not be able to give the customer unlimited pleasure.

DESIGNBOATS SWITZERLAND & COMPOSITEWORX

Designboats Switzerland and compositeworx have many years of know-how in the development and construction of high-quality sports boats and yacht tenders. Together with the modern composite production infrastructure and the experience gained from many custom-made projects, this ensures that the boats made by designboats.ch and the custom-made one-offs developed and built by compositeworx.ch deliver the agreed result and that clients know that their project is in experienced and reliable hands. It is therefore not surprising that an exclusive and luxury ‘Owner's Tender’ for a mega yacht is currently being built in the production halls of compositeworx. After thorough evaluation, yacht owner and the project team appointed by him decided in favour of the renowned Swiss shipyard situated on Lake Constance just next to the German border.

Q-Yachts

Leave nothing behind with the Q30 zero emissions electric day cruiser from Q-Yachts. The future of the electric superyacht tender is here

Mr. Janne Kjellman, the founder of Q-Yachts and a keen sailor, set out over a decade ago to develop a silent and sustainable propulsion system for boats. The Q-Yachts project was developed with the clear vision of designing a motorboat which can offer the same experience of speed, relaxed voyage and silence, that you will experience when sailing a performance day cruiser sailing yacht.

At the heart of the Q-Yachts concept is the silence. Thanks to the innovative electrical propulsion technology and the hydrodynamically optimized hull, the boat produces minimal noise, wake and zero emissions. This means that you can actually speak with a normal voice while driving. Hence, with the Q-Yachts Q30 electric day cruiser, the journey truly becomes the destination!

Having worked in stealth mode with the project for several years, Q-Yachts launched the first model, the Q30, to the world market in 2018. The Q30 fully electric day cruiser is a unique concept, where design meets state of the art technology and environmental sustainability to give a revolutionary boating experience.

The goal has also been to develop a boat which is easy to use and own, and which puts the focus on enjoying the ride with minimal hassle. The Q30 boasts the following features such as:

  • Easy charging with 110V/20A or 220V/10A
  • Minimal maintenance
  • 5 hour drive time at 9 knts
  • Easy to use custom App installed in the iPad supplied with the boat for monitoring the boat’s systems
  • The boat fits onto a trailer or into a 40’ container (for longer shipment)

In addition to the unique, silent and relaxed boating experience offered with the Q30, one key challenge addressed in the Q-Yachts project was the charging requirements of the batteries. The efficient battery banks (only 30kWh), allow charging to be done pretty much anywhere with 220V/10A (or 110V/20A) and using a standard plug. This opens up the possibility to use the boat much more widely than most other electric motorboats currently on the market. Charging time is still only approx. 12h from 5% to 95%, so you can “Drive by day -Charge by night!”

The challenge for any electric motorboat is the issue of range. Thanks to the extremely energy efficient electric propulsion system, the light composite sandwich construction and the hydrodynamically optimized hull, the Q30 is very energy efficient and offers a respectable range of 10 hours continuous driving (or 60NM) at a comfortable and completely silent speed of 6 kts.

Even at a speed of 9 kts (still with next to no noise from the propulsion) the Q30 offers a driving time of 5 hours or approximately 43NM. Hence you can really drive all day without the need to recharge.

However, should you need to feel some speed, the boat still offers a top speed of 15 kts with 1.5 hours of continuous driving. More than enough for your average superyacht tender.

Q-YACHTS TODAY AND INTO THE FUTURE
Based in Helsinki and with production located in Finland, the production of the Q30 is already up and running. Several boats have already been delivered to their customers around the world, and more boats are currently in production awaiting delivery to their owners. To ensure the highest of quality, the boats are built by experienced Finnish craftsmen.

Since the launch of the Q30 to the market, the unique concept has been met with great enthusiasm and praise with
enquiries on the Q30 coming from all around the world. Further developing the Q-Yachts concept, the next step is to create a technology assisted driving experience with the ultimate goal of an autonomous driving option in the coming years.

In addition, Q-Yachts is currently developing a version of the Q30 aimed for commercial use as a water limousine, with an option for hydrogen/fuel cell power. This Q30 eLimo is scheduled to be out on the market very soon within 2020.

With the unique concept and the innovative technological developments, Q-Yachts has its sights firmly set on becoming the global market leader in the electric motorboat market – the Tesla of the Seas!
