Recreational craft manager since 2013 and diving coach Valters Preimanis, Any water transport that sails and uses propeller propulsion, such as cutters and yachts, may wind cords, ropes, ends or nets on the propeller. Nets that are set and in the water for fishing purposes are most often wound. It is often necessary to go into the water to remove the entangled foreign matter from the propeller. It is necessary to undergo professional diving training to perform diving in a safe manner.
If necessary, we call a diver, a diving specialist will come and remove the nets, call 220-77-202

What are the signs of twisting the rope
- If the craft is powered by a motor, there is a rapid loss of power
- The engine stalls and cannot be started

Action in case the propeller on the ship or yacht is wrapped
- To make sure that it is wrapped, we take the croissant and pull it up, closer to the surface of the water
- Twine, cordage, rope or netting is seen
- We can cut everything and get up on the boat so that it does not disturb others
- Do not dive in nets, it is a big risk for divers
- Assess water temperature, waves, current
Cutting the rope from the propeller
- The captain means the person in charge, the captain stays on the boat
- The event usually takes at least one hour
- Need a sharp, neat knife, it needs to be tied around the palm
- There may be snails on the propeller and hull, gloves should be worn

- We are wearing clothes, or better yet a 5mm wetsuit, which helps in the conditions of the Baltic Sea
Diving equipment on the boat
- It is necessary to undergo diving training to perform safe diving
- Diving without training can be deadly
- Maintain a full set of diving equipment if possible
What to check after removing the rope
- If there is a propeller with a valve, it's all ok
- If there is a Saildrive propeller, there is an oil seal behind it
- Check the condition of the oil as it looks, if the oil is white as milk, it is an emulsion, there is water in the gearbox, the bearings on the gears are endangered
If it is dark at night and it is difficult to remove the rope from the propeller
- Call a friend, call helpers from the port

How to avoid network entanglement
- Use cutting blades that can be attached to the propeller
- The cutter can cut the ends of the rope and the wire of 5mm steel
- Cutters cannot cut ropes and metal cables thicker than 5 mm
Why there are networks in the Daugava
From the Vanšu bridge to the sea is the territory of the port of Riga. The law stipulates that nets may not be located closer than 100 meters from the fairway, fairway, but it has been proven in life that there are many nets in the Daugava and the Gulf of Riga. If sailing on the Daugava, it may be necessary to know that VHF channel 9 is being used for traffic management.
