The most important hand signals and radio rules for sailors in Istria

Communication is often a challenge on the water. Wind noise, waves and distances make it difficult to communicate. In Istria, as in other sailing regions, it is therefore crucial that you know the common hand signals and radio rules. They will help you to avoid misunderstandings and navigate safely. In this article, you will learn everything you need to know about these means of communication in order to sail safely and efficiently.

The meaning of hand signals on the water

Hand signals are indispensable, especially in marinas, when mooring and casting off, and in situations where direct communication is not possible. Especially in Istria, where the harbours are often busy in the summer months, it is important that you communicate clearly with the crew or other boats. Here are the most important hand signals you should know:

  1. Stop
    Point upwards with the flat of your hand, fingers closed. This is the universal sign to stop all manoeuvres. It is often used when mooring or in narrow passages.
  2. Slow
    If you want to signal that you are slowing down, hold out the flat of your hand and move it slowly up and down. This signal is particularly important when you are close to swimmers or other boats.
  3. Get closer
    Raise both arms in an arc and pull them towards your chest. This sign indicates to the other person that they should come closer – for example, when you’re lying down or when help is needed.
  4. Keep distance
    To indicate that a boat should keep its distance, stretch both arms out to the side. This gesture clearly shows that you need more room to manoeuvre.
  5. Rotate
    If you want to signal someone to turn the boat round, stretch one arm out straight and make a circular motion with your hand. This is particularly useful in narrow harbours or if you want to turn the sailboat around.

The radio rules for sailors in Istria

In addition to hand signals, radio plays a central role in communication at sea. Istria has a well-developed radio infrastructure that you can use for emergency calls, enquiries or coordination with harbours. Here are the most important rules and tips for radio communication:

  1. Channel 16 – The emergency call channel
    Channel 16 is the international emergency and call channel and is also strictly adhered to in Istria. Always keep this channel free for emergencies or important announcements. If you use it for other purposes, you may risk a fine.
  2. Short and clear announcements
    Bei der Funkkommunikation gilt: Weniger ist mehr. Sprich in kurzen Sätzen, wiederhole wichtige Informationen und vermeide unnötige Details. Verwende auch international anerkannte Begriffe wie „Roger“ für „verstanden“ oder „Over“ für „Ende der Übertragung“.
  3. Radiotelephony procedures
    Start each radio transmission with the name of the receiver, followed by your own boat name. For example: ‘Marina Pula, Marina Pula, this is sailboat Bella Vita, over.’ This ensures that the receiver immediately knows who is addressing them
  4. Security messages
    In Istria, safety messages are also issued by radio. These often concern the weather situation, nautical warnings or special instructions for sailors in certain areas. Make sure you listen to the relevant channels regularly, especially in changeable weather conditions.
  5. Making emergency calls correctly
    If you find yourself in an emergency situation, make the distress call on channel 16. Start with the word ‘Mayday’ (repeat three times), followed by the name of your boat, the position and a brief description of the emergency. For example: ‘Mayday, mayday, mayday, this is sailboat Bella Vita, position 44°48’ N, 13°50‘ E, we have a water ingress, over.’

Combination of hand signals and radio

There are situations in which you can use both hand signals and the radio. For example, when entering a harbour, when you contact the marina by radio and at the same time communicate with the crew on board using hand signals. This ensures that all processes run smoothly.

Our summary

Hand signals and radio rules are indispensable tools for every sailor, especially in such a lively sailing region as Istria. Mastering them will not only help you communicate better with your crew, but also ensure that you react correctly to unforeseen situations. Take the time to practise them – your next sailing trip will be much more relaxed and safer.
