FLINsail

The FLINsail is a modular solar system that is hoisted and guided in the mast groove like a sail. With the help of the patented FLIN mast sliders, the FLINsail can be clicked into the mast groove above the mainsail. Due to its sliding bearings it can be optimally aligned to the sun and achieves highest efficiency. With the guide lines the solar modules can be aligned synchronously. The number of solar modules of the FLINsail is adapted to the energy consumption of the sailing yacht. Due to the modular design, versions with two to six solar panels are possible.

The FLINsail offers many advantages

Due to the elevated position on the mast of the sailing yacht, the solar modules are rarely shaded. In addition, the modules are cooled by good rear ventilation, which gives them even more power.

Perfect angle - Highest efficiency

Crucial for the maximum output of a solar module is its alignment at the perfect angle. For maximum energy generation from solar radiation, the solar modules in the FLINsail can be aligned synchronously with the sun. This enables maximum energy generation even in the evening hours when the sun is at its lowest. If the FLINsail is positioned at the perfect angle, you can even achieve greater charging currents than using a standard shore power charger.

 

Try out the model to the right to see how the angle of incidence of the sun affects the efficiency of a 100 W solar panel. Drag and drop the panel or click on one of the alignment points.

Your customised solution

Thanks to its modular design, we can optimally adapt the FLINsail to your individual energy consumption. With just two solar modules, the FLINsail solar sail supplies the classic consumers of a 30-foot yacht with sufficient energy. In the current maximum version with six solar modules, the range of an e-motorised sailing yacht is more than doubled in calm conditions.

It is very simple

The time required to set up and take down the FLINsail is less than five minutes. The FLINsail is inserted directly from the FLIN bag with the mast sliders above the mainsail and hoisted like a sail. When the system is hauled in, the solar modules slide directly back into the handy FLIN bag so that the FLINsail can immediately be stowed away easily and in a space-saving manner.

Stay flexible

The FLINsail offers you the possibility to keep the free space on deck, at the same time not having to change anything on your sailing yacht and still being able to mount such a large solar surface that supplies all electrical consumers including the electric motor with sufficient energy. With the FLINsail, you don't take any space away from yourself, but on the contrary, you make unused space on your sailing yacht usable.

Be independent

With the FLINsail you can charge your batteries from sunrise to sunset. You are thus supplied with enough energy when you want to sail under mainsail or stay at anchor in the bay, far away from crowded harbours. You can choose where you want to go and where and when you want to take a break.

We pay attention to sustainability

By using high-quality and durable materials, we extend the service life of the FLINsail. The modular design also allows for the constant replacement of individual components, so that only the affected component needs to be replaced and not the entire product. To keep transport distances as short as possible, our suppliers are located and produce in Europe.

Installation of the FLINsail

To charge the on-board batteries with the FLINsail, a solar charge controller is required. We are pleased to offer you one with the FLINsail.

In order to use the FLINsail, no constructive changes have to be made to the sailing yacht. The FLINsail is a plug&play system. If it is used, the cables can be laid flying through the companionway or a hatch. Alternatively, a fixed socket can be placed at the base of the mast as a deck feed-through.

Alignment of the solar modules

To align the solar modules in the FLINsail with the sun, use the guide lines. The solar modules rotate synchronously around the horizontal axis to the desired position. Use the clamp to fix the solar modules in the desired orientation. By pivoting the main boom, the FLINsail can also be aligned around the vertical axis.

We optionally offer solar charge controllers with Bluetooth interface. The charging current of the FLINsail can be monitored via a smartphone. If this is at maximum, the solar modules are optimally aligned.

 

Resistance of the FLINsail

We use solar modules with multibusbar technology: These are extremely durable and can therefore withstand high wind loads. In the product test phase, the semi-flexible solar modules had to withstand gusts of wind of up to 38 knots without suffering any damage. Thanks to the innovative manufacturing technology, the solar modules are very fail-safe and have a long service life.

We have already experienced a lot with the FLINsail. Tell us your experiences and stories too.

On the Balena washing is done with solar energy

As "liveaboards" on a sailing ship, we naturally sail a lot. Currently we are sailing through the Norwegian fjords. But every Friday is "boat cleaning day" for us. Today it was time to do the laundry again. We have a 3kg wall-mounted washing machine from Asia, which is designed for small one-room flats, but is used a lot on sailing boats and campers. We are very happy with the machine, it washes quietly and uses little electricity and water. For a 60° wash cycle it needs 520 Wh and about 20 litres of water. Today is a sunny day, ideal for drying clothes. We are well anchored on a skerry. At noon we put up the solar sail from FLIN to generate electricity for washing. Now we have washed two drums, and also cooked pasta - but already at 4 pm we have more power in the batteries than at noon.

Thanks to the FLINsail, we are truly independent and can live wherever we want.

Olga and the power-guzzling fridge

Who doesn't know it? The yachting cliché par excellence: you're sitting on deck and it's 30 degrees in the sun - now a nice cold beer. But the boat owner comes out from under the deck with a warm beer: "I'm sorry, but at anchor I always have to turn off the fridge. I can only run the power guzzler on shore power."

We knew that too, but thanks to the FLINsail, this problem is a thing of the past. We have already mounted a solar panel on the deck, but it is not really efficient. Especially in the evening hours, the charging of the battery fails almost completely, because the sun's rays simply don't hit the module at the right angle. You often think that the solar power stagnates a lot in the evening because you start to freeze, but with the FLINsail you can still expect enormous charging currents of up to 10 amps even shortly before sunset. We have even developed a certain ambition, as you can look via an app to see how much energy the FLINsail is delivering. So we always find the perfect alignment to the sun. All in all, a very successful product that especially facilitates anchoring and thus ensures the enjoyment of cool drinks, among other things.

Mina travels electrically from Marstal to Kiel

Going sailing in summer in the northern climes doesn't always mean good weather. But we remember the perfect summer in 2019 with lots of sun, little wind and visibility into the water that reached up to eight metres deep.

At the same time, for sailors with electric motors like us, this means constantly being afraid of not getting far enough - But thanks to the FLINsail, this was gone that summer. At times, we were able to motor for eight hours in one day without our battery showing below 50%. This year we also had some advantages in the harbour compared to non-FLIN owners. The electricity in Marstal, which was supposed to come from the blue boxes, did not work. We still remember how an angry sailor next to our boat shouted at the harbour master and asked us if we had electricity.

Another man watching the spectacle pointed at our FLINsail and laughed: "Yes, I think THEY have electricity". So we could sit back while the others didn't know how to feed their consumers.

The eight-hour tour back from Marstal to Kiel also went smoothly for us, despite the calm. The e-motor whirred quietly while we enjoyed the sun. Thanks to the FLINsail, we were able to cover the 35 nautical miles without any problems at sea. An all-round successful holiday without the so-called range anxiety.

FAQ

Can I use the FLINsail while sailing?

During sailing, the FLINsail is stowed in the FLIN bag and stored in a suitable place, e.g. below deck. In a calm or at an anchorage, the FLINsail is set above the furled mainsail.

Do the mast sliders of the mainsail have to be unthreaded to set the FLINsail?

No. The FLIN mast sliders can be inserted into the mast groove above the mainsail. If your mast is equipped with a T-rail, we supply matching mast sliders to put on. See mast systems.

How many FLINsail variants are there?

The FLINsail is available in the following six variants:

2M-FLINsail 174 W light

2M-FLINsail 174 W tough

3M-FLINsail 261 W

4M-FLINsail 348 W

5M-FLINsail 435 W

6M-FLINsail 522 W

What is the difference between the 2M-FLINsail light and tough?

In the light version, there is no reinforcement with plates behind the module. It is therefore somewhat cheaper and also very light. If the FLINsail is to be used in strong winds, we recommend the 2M-FLINsail tough. 

In the FLINsails with three or more modules, the upper and lower solar modules are stiffened.

How do I store the FLINsail?

The FLINsail is stored protected in the handy FLIN bag. The bag has been designed not only to facilitate assembly and disassembly, but also to protect the solar system from light external influences through padding and reinforcement.

The FLINsail can be stored in the FLIN bag below deck or in a back box.

Do I need a charge controller to use the FLINsail?

Yes, a charge controller and a suitable connector to the FLINsail are required. If you have a suitable charge controller and interface, you can connect your FLINsail

We will be happy to advise you and offer a charge controller and a plug-in connector for your FLINsail.

What can a deck implementation look like?

The FLINsail is a plug & play system. Therefore, in order to use the FLINsail, no constructive changes have to be made to the sailing yacht. If it is used, the cables can be laid flying through the companionway or a hatch. Alternatively, a fixed socket at the base of the mast can be used as a deck grommet.

Can I use the FLINsail on mast systems with furling mainsail?

Most mast profiles that are designed for a furling mainsail have a second mast groove in which the FLINsail can be placed.
