ships - electric boats - electric catamaran - other objects

Fully electric boat or unique, fitness version?

Small catamaran Serenity 550 is absolutely right choice.

Have you ever seen such a small catamaran where you can safely walk through its entire length?
Rowing, hands pedalling and legs pedalling in one boat or just a fully electric boat?
You decide about the final deck arrangement.


You won’t hear from us „it’s impossible” at the start.

First we have to collect assumptions and expectations. Then it is possible to consider whether they are consistent and feasible.

Sometimes they need to be modified for various reasons.


Designing can be done in a conservative way like copying and changing solutions already known on the market. There is another way so the new ideas can be developed regardless of current trends.

It depends on why and for who. We definitely prefer the second approach.


We know that corporate governance and justified bureaucracy reduce the risk of failure of each project.

We are able to  adapt in various organizations respects to the client’s needs and capabilities.


This element is necessary to keep commitments and bring projects to completion.

Responsibility forces us to implement each stage of the project with full commitment.

This is how our approach to work and co-operation can be briefly described.

Small catamaran Serenity 550

as universal floating platform

Using Serenity 550, we can build boats with various functions, e.g. a floating kiosk, a warehouse, a mini houseboat, or connect several pieces using flexible connectors to create a water train.

Length 5.5m, breadth 2.5m

Based on this platform, you can build boats with various functions.

The deck is a sandwich structure with a thickness of approx. 30 mm.

The floats are divided by bulkheads into four watertight compartments. Each of them is equipped with an inspection hatch with a diameter of 20cm.

The float is designed without a sharp end of the waterline at the stem. In this way its entire length can be safely use without excessive trim by head.

The whole platform weights abt. 360 kg.

Few other arangements of catamaran Serenity 550

We like to spend time on water. It is nice to use SUP, kayak or water bike in peace and quiet.

It is also good to stay sporty with ride a bike and workout in the gym with friends.
So, why can’t we do it all at once?

And the simple answer is because it is difficult to imagine a suitable floating equipment for this.

That is why we have designed this unique big water bike with electric support drive.

Now we can!

Serenity 550 Fitness.

The big water bike.

Available in few versions.

In fact this is an open project.
It means that a client can decide about final arrangement.

How many  drive stations and seats, sunroofs or maybe fixed roof with PV panels and walls.

For example someone would need only helmsman drive station and five seats for passengers on double or single seats.
No problem. You decide.

And here is a small, fully electric catamaran for those who do not like any water bikes.

In general we prefer a silent and zero emission drives.

The proposal of a very interesting electric catamaran.

For people who do not associate relaxation with movement. It is enough for them to stay on water with their family or friends.

Non-standard appearance, easy, comfortable and safe operation.

You decide about the final arrangement of the deck.

Serenity 700

fully electric, recreational boat

Small tourist boat ensuring lots of fun on water.

They are not disturbing peace and quiet of other people enjoying their rest in the vicinity.

Available in various colours, outfitting and arrangements.


Our first choice is electric motor because it is much higher efficient than diesel or petrol engine.
Additionally electric motor is simple, quiet and clean.

The motor is powered by LiFePO4 battery kit of total capacity amounting to 300Ah. This is enough for the boat to carry passengers for ca. 6 hrs. with the speed of 5.5kn.

The battery is charged from regular power socket for up to 6 hrs.

This kind of propulsion requires no maintenance on the user’s part. Except for connecting the power cable to wall socket.

Of course the batteries require special care in order to maintain their longevity with full capacity. However this is commonly known from using batteries in laptops or smartphones.

This electric boat is proposed in three different versions:


Even if you are not a supporter of eco drives or simply need a boat for a longer cruise. If you do not want to use your boat with necessity for charging you may still use the Serenity boat.

We have provided solutions for such situation.

First of all we suggest a hybrid drive in such situation. A small an quiet diesel generator will be installed on board to charge Li-ion battery.

Another and very simple solution is a small outboard engine. Transom and stern are ready for such situation.

Like a camper on water - eco boat as a houseboat.
