VAKE De-Icer System is perfect for winter storage of boats, jetties, and docks. It has no machinery or electricity underwater, which guarantees high safety and reliability. Dual pumps with a single power supply provide a doubling that doubles the safety. These powerful pumps with high reliability work carefree year after year.
One of the major advantages of VAKE De-Icer System is the lack of propellers. It allows the system to do not risk sucking in debris floating in the water or lying on the seabed. This is large important, especially for shallow water jetties.
VAKE De-Icer System use high performance pumps that creates large amounts of hot water bubbles flow for winter de-icing. And its system are also used to provide year-round benefits.

Supplement your VAKE power generator with VAKE alarms that send you a text message in the event of a power failure so you can sleep better than ever.


2 x Air Compressors Model V-12 (80W, 220-240Volt, 50 / 60Hz, less than 40dB, 7.15kg each)

2 x 20m Air hose with suspension device and connection (for max. 12-13m water line)

4 x Weights for center ramps
8 x Tampers for hanging air hose
2 x Hose clamps with quick screw
2 x Hose connection nipple with O-ring

VAKE’s air compressors are quality built for continuous operation year in and year out. The casing and frame are made of aluminum for the longest life. The pumps are IPX4 rated which means they can be used outdoors under a roof. Multi-stage silencers and internal rubber suspensions as well as external rubber pads guarantee a very quiet operation of less than 40dB.



Boat De-Icer Manual


VAKE model V-12 is suitable for holding ice-free around a max 12-13m boat (about 12m waterline)

VAKE model V-12 + is suitable for 15-16m boat (about 15m waterline)

All types of sailboats that have either S-drive, propeller shaft or outboard can advantageously be stored in water. Also all types of motor boats with propeller shaft or outboard.

However, we do not recommend winter storage of motorboats with gears. The bellows of the drive lie at the surface and are exposed to a prolonged power failure.

The size of the watch depends on the size of the boat – There will be a safety zone a few meters outside the boat’s hull.


VAKE is often used to protect jetty or other sensitive equipment. The perimeter / edge of the dock should then be max24m, and 30m for Plus, respectively.

It takes about 1-2m depth under the bridge to get a proper circulation of hot water. If the depth is less than 1m, the circulation will be a little worse regardless of whether you choose VAKE or competitor but then VAKE is also the only option since competitors with propellers suck in debris from the bottom.

Proximity to deeper water gives a better effect in prolonged cold weather.


This package is for one boat only. You should not buy a package and divide up to two boats. The hoses should be hung on each side of the boat, thus creating an upward flow of water which is then angled out to the side of the boat’s shape.

If, despite the high operational reliability, a pump would cease to function, the remaining one will maintain a reasonable wake up pending the repair of the broken pump.

Be sure to place VAKE hoses before the ice settles!


The compressors must be positioned so that the part of the hose can be pulled above the water without squeezing or strong curves. The hose may only go in the ONE up and one downhill. This is when condensation water must either flow down through the hose into the sea or back to the compressor.


Boat De-Icer Manual


Find a suitable place where you can conduct air hoses and where the compressors can stand all winter. You can advantageously place the compressors inside the boat and then take advantage of the excess energy giving a scant heat in the boat. The compressors are IPX4 rated and can therefore also be placed outdoors under roof / tarpaulin. Regardless of the choice of location, care must be taken to ensure that the air supply is not interrupted if large amounts of snow come.

NOTE !!! Hose and pumps must under no circumstances be placed below the water line inside the boat!

When placed inside a boat, air hoses can be introduced through a ventilation valve. Or make a plate with two holes where the plate can replace the glass in an openable window.

Avoid bending or squeezing the hose that obstructs the air.



Unroll the hose and wood on two stainless steel holders per hose. One holder is pulled all the way to the end of the hose and the other just past the red marking 8m from the air connection.


Suspension at the end of bubble hose.

Each hose requires four tampons. A tamp each is attached to the ring in the middle of the chain on the holder. In addition, two tampons must also be attached directly to the hose with an even distance between themselves.

Secure the placement of the stainless hanger near the red marking (see picture above) with one of the bundles provided.

Remember! The hose may only go in the EN up and downhill above water. Avoid breaks or crush on the hose. If this is done, condensation water cannot form ice plugs. Cut hoses to the right length if they are too long.

Unroll the hoses along the sides of the boat.

If it is dark water, you can start by hanging the hose a few inches below the surface to make it easier to check that the hose runs straight.

The hose should be hung 11⁄2 m below the surface. A little deeper at the connection to the air hose and a little shallower at the end of the hose. It is an advantage if the hose hangs towards the center of the boat under the boat. Therefore, hang the front and aft tampers near the center of the boat (in front and aft one can often advantageously cross the tampers and place the lifting point on the other side of the boat). The awake gets bigger when the bubbles hit the hull before they reach the surface. The hull then angles out the stream with warm water, out of the boat.

Boat De-Icer Manual

If the hull has strong guide rails (motor boat) that stop this current, it is more advantageous to hang the hose outside the hull.

It is important that end tampons pull in the longitudinal direction of the hose to extend the hose. Therefore, attach these as far back and forward as possible. An angle of up to 45 degrees can be advantageous.

Suspension. Angle of tamp illustrates how it should hang underwater. This is to stretch the hose.

If you want to use the entire length of the hose on a boat shorter than 12-13m boat, it is advisable to make a temporary point of a plank or the like that keeps the tamp from the boat longitudinally. And attach one end to the jetty or similar.


Shorter boat than 12-13m, then adjust the length of the hose. Surplus hose is strangled by cable ties.

If the boat is shorter than 12-13 meters and it is difficult to get to the desired angle of the end stamps, you should move the last holder a bit into the hose. This is to get a good angle on the tamp. The remaining hose stump is “switched off” with a cable tie.

Keep in mind that the warmer bottom water is heavier than the surface water, which means that if you stop the torque in the current, the hot water will immediately turn down again. This can be eg happen if you have a boat neighbor nearby. Admittedly harmless, but that explains why your watch can never extend beyond the nearest boat neighbor or dock.


Note that the hose above water may only go in the EN up and down the downhill as condensation water must either run down the hose in the sea or back to the compressor.

To keep ice-free around a jetty, hoses are placed 1.5 m below the water surface along the outer edge of the jetty. In order to ensure proper circulation of warm bottom water, the supply must not be hindered. In a shallow bay, the supply of warmer water can become worse during longer periods of cold.

Unroll the hose on the dock and make sure it is not spun. Attach the tampons to the appropriate places. Then slowly release the hose into the water.

You may want to start by placing the hose shallow to visually check that it hangs horizontally. Then drop it down to the correct depth with the tampers.

It is important that the tampers at each end pull in the direction of the hose and are preferably angled 45 degrees (see pictures under section 3. (boat)). If the hose is longer than the bridge, you can move in and shut off part of the hose using cable ties (see picture on previous page).


Screw the hose bracket (brass) into the air compressor by hand so that the rubber bushing seals. Normally, a key is not used when the rubber bushing is crushed. It is enough with hand power! Connect the hose and tighten the supplied hose clamp. During test driving, it should not breathe air.


The hose should hang as horizontally and straight as possible for an even distribution of the air bubbles.

The hose should hang as horizontally and straight as possible for an even distribution of the air bubbles.


When running in calm weather, you should be able to see how the bubbles cause water to flow up and reflected outward by the boat hull, which allows water to flow out of the boat hull (clearly visible as the air bubbles settle on the surface and travel with the current). It is this stream of warmer bottom water that keeps the ice away when it gets cold.


If VAKE is used for a dock, it is usually not possible to achieve the above mentioned angulation of the current. Focus on verifying that there is a steady stream of bubbles throughout the length of the tubing.

If there is a different amount of bubble along a hose, it may have screwed or not hung horizontally. Lift up the tampers and try to get this right. A certain bump in the amount of bubble is harmless. If some of the hose hangs deeper it may result in smaller bubbles at this point. Take action by lifting the correct tamp and observe the amount of bubbles.


When the above steps are completed, you can turn off the power to VAKE and wait for the ice. When the ice is in danger of collapsing, you can start up VAKE current generators and enjoy a carefree winter without ice. At a first start, it may take a few minutes for the water to blow out of the hose and a smooth bubble flow has been achieved.


Check the air filter and clean if necessary when the season is over. Find the small lip and use a flat screwdriver to loosen the plastic cap on the pump’s “roof”. Vacuum the filter and reassemble.

Every 5-6 season the membrane should be changed.


A modern fiberglass boat (plastic) can theoretically be stored completely frozen in still ice. However, a watch is required to protect when the ice screws on due to waves and wind. This is far from the most serious threat. The absolute greatest danger is that hull penetrations freeze. A current generator works by lifting up warmer water. This to some extent warms the interior of the boat as well. Water in wells can freeze despite it if it is very cold in the air.

Winter preservation of hull penetrations in any way is a must for winter storage in water and should never be neglected.

There are different schools when it comes to protecting themselves from freezing implementations. You should check with your insurance company what they have for directions.

Some prefer to leave ball valves open to secure them against freezing.

Others recommend closing the faucet on the hull bushing and then filling with environmentally friendly antifreeze in the hose.

Whichever method you choose, we recommend that you wrap insulation around the base of all ducts and the bottom of the connected hose. It is advantageous to use hose insulation in foam from the nearest construction company. With insulation in this way, the ducts are heated from below by the warmer water.

Never pour toxic glycol into the wild! Glycol is very toxic. A cup is enough to kill an adult. Pets are a major risk group as glycol tastes sweet. Also called “environment” – glycol is a petrochemical product with much debated danger.

For a carefree winter preservation, we recommend VAKE organic antifreeze that is completely non-toxic!

Remember, some insurance companies require you to report extended time in the water for year-round storage in the water.


Tänk på att anoder slits i onödan om du kopplar in landström till laddare och båtens system. Det finns olika metoder att minska detta problem. Men den effektivaste är att helt enkelt inte koppla in båten och att istället dra skarvsladdar direkt till VAKE utan att koppla in båten på landström.

Har du blybatterier i båten är de vinterkonserverade om är fulladdade inför kylan. För underhållsladdning rekommenderar vi solpaneler som fungerar bra genom en transparent presenning. Vi rekommenderar självklart SUNBEAMsystem solpaneler som har en mängd fördelar jämfört med andra på marknaden.

Litiumbatterier kräver ingen underhållsladdning


Never allow any part of the mooring to hang near water as it can get stuck in the ice.


A common prejudice is that winter storage in the water makes the indoor environment more humid compared to land storage. This is not true!

The humidest season in a boat is September- October. Then the majority of us all have our boats still in the water. During this time, surprisingly many people are tired of their otherwise well-cared boat and leave it without proper dehumidification. This period lays the foundation for molding, “boat odor”, oxide on cables and electronics. A dehumidifier is therefore recommended for ALL boat owners. An electric dehumidifier designed for cold spaces is superior. Many use old dehumidified salt dehumidifiers, instead we recommend GOBI DRY Brick which is a more modern, cleaner and 100% reusable alternative.

From November onwards the water is warmer than the surroundings and therefore heats the boat from below.

During the winter this effect becomes even more evident. With VAKE switched on, your boat is heated compared to ambient air temperature.



Another moisture problem is the water that forms in a diesel tank and comes from the humidity of the air. The water in combination with Diesel causes bacteria to thrive and a dangerous mourning is formed.

This is a problem year-round and regardless of the type of winter storage. But it is a good habit to leave the tank completely filled with long-term storage to help counteract the condensation water. There is a solution that completely stops the condensation water and it is GOBI DRY Tank that we highly recommend.

Generally, many are surprised how little it grows on the bottom when it is colder in the water. Many of us have summer as a reference. The vegetation stops gradually during the fall and then goes down to a minimum. Already at the beginning of March, the observant may notice that mucus is beginning to thrive in the spring light. However, this is surprisingly easy to brush away with a suitable device. Sea tulips usually settle for just one week in the summer, which varies with locality. You can subscribe to SMS alert for this to more easily focus the cleaning of the boat bottom.



A fiberglass boat normally attracts water, which means that after maybe 20-30 years, bubbles can develop. When stored ashore, the plastic is dried, which slows down this process. By epoxy-treating the boat, you prevent water penetration, which is always a good idea. Since a boat that is stored in water in winter is twice as long as land storage, you should consider an epoxy treatment of the boat.
