We're looking for an investor! 🚀 We're creating a revolution in active water recreation!

Do you know that feeling when your only options for a fun day on the lake are a kayak, a SUP, or a small, uncomfortable two-person pedal boat? It's time to change that!

As a design studio, we decided to redefine active recreation on the water. We're not interested in cosmetic changes; we're focused on new niches and real human needs!

Our work resulted in the Serenity 550 - a versatile, safe, floating platform that's ready for production!

What makes the Serenity 550 stand out?

✅ It's not just a boat! It's a platform you can build different versions on - from a relaxing electric one to a workboat, and our favorite: the Fitness version!
✅ The Fitness version is a gym on the water! By pedaling with your hands or feet, or rowing, you can work out your entire body, all while spending time with loved ones on board. Say goodbye to boredom on the water!
✅ Unprecedented stability and safety: 4 adults on one side won't cause any panic, and each float is divided into 4 watertight compartments.
✅ Exceptional maneuverability: Thanks to an innovative propulsion column designed and built for us by MDPengineering, our platform can turn almost in place!

This isn't just a theory!

To prove our project makes sense, we built three prototypes. All solutions, from the floats to the propulsion system, have been tested in real-world conditions.

We are looking for an investor and a production partner!

We are a design studio, not a manufacturer. We have a ready, tested project and are now looking for a partner to help us commercialize it. Production requires two facilities: one specializing in laminates and another in machinery and equipment.

If you're looking for a ready-to-go business idea in the marine industry and want to tap into a market gap, get in touch! This is a clear path to success!

The floats were cleaned and painted with antifouling to a height of 40 cm.
At the same time, the locker flaps were renovated.
The catamaran was parked for the winter in the parking lot of the CycloSport bike shop in Chwaszczyno near Gdynia.
We thank the shop team for their help.

The floats after two months in harbour water without antifouling coat.
Really foulded.
Our mistake. It will be a lot of work to clean and polish the floats.
We will coat with antifouling paint for a next season.
2024 summer season is finished for Serenity 550 Fitness.
thanks a lot for a kind cooperation. 👍🙂

And that's a very good concept. 👍

Yesterday, we had a great trip with five friends.
Five adult men 40+.
An hour was enough for the entire team to complete cardio training. 🌞

ATTENTION
Serenity 550 Fitness
moors at the Galar Gdanski’s pier
Dokowa 1G st., Gdansk
https://www.galar.org/

If you would like to do a cardio training on water of the Motlava or Martwa Wisla river, we invite you.

FOR FREE

A trip there and back along the Motlawa river takes about 60 minutes with an average effort of 2 people (it is best to have 3-4 people – electric support is only 350W)

1. You need to go to the Galar’s bar/ticket office counter.
2. The battery is mounted on the back of the helmsman’s seat (the Galar staff must be reminded about it).
3. Before boating, familiarize yourself with the operation of the steering wheel connected to the rotating drive column (active rudder, the catamaran can rotate in place). There is a propeller position indicator above the steering wheel (the wings show which direction the thrust force is acting, and the tip of the pointer shows which direction the stern of the catamaran is being pushed).
4. It is good to know traffic regulations in port canals.

Hello everyone,
Serenity 550 Fitness will be moored in Gdansk very soon.
The most probably it will be possible to rent.
In the next post we will provide the address of the marina.

What a nice surprise. After two more weeks in water the weight didn't increase.

08/03/2023

New measurment shows that 0.02g of water was absorbed.

02/03/2023

And surprise. 0.03g of water more inside the propeller. Water has found some free cells for fill up. OK then, observation is ongoing.

22/02/2023

It's the day of weight measurement again.
So, from the beginning we have got 0.09g + 0.03g + 0.01g +0.01g = 0.14g of water inside the propeller material. This is abt. 1.7% of dry mass. What influence could has on resin properties this amount of water? We need to find out.
