Loud shouting during a mooring manoeuvre is not a sign of confident ship management. Other crews in the harbour quickly suspect, usually rightly, that the planned manoeuvre is going wrong. The mooring manoeuvre may not have been discussed sufficiently in advance or the situation in the harbour may have prompted the helmsman to spontaneously change his plans. Communication can then be impaired even on small boats by wind noise or loud outboard motors. On large yachts, the distance between the helm and the foredeck simply makes it difficult to understand commands clearly.
If casting off is usually still problem-free, situations can arise, especially when mooring in unfamiliar harbours, which then make it necessary to coordinate with the crew again. Radios or Bluetooth headsets can help here.
However, as with FM radio systems, they work in a simplex manner, with only one channel available. Speaking at the same time does not work; if you want to say something, you have to press the PTT button (Push to Talk). This requires a certain degree of radio discipline. Anyone who tries to interrupt the other person will not be heard. If you monologue for too long, the channel is blocked and there is no answer.
Many models have a so-called VOX mode so that one hand is not constantly tied to the radio. The device recognises when someone is speaking and switches the channel to open. However, this automatic function did not work flawlessly in the test.
Four PMR radios were tested: the Motorola T92H2O, the Retevis RT647 and the WT-320 and WT-330 from Simvalley. A headset for the Simvalley devices also took part. In addition to the different functionality, the prices also vary greatly between 40 and 123 euros.
The walkie-talkies all did their job well. Switch on, select the same channel, press the button and speak - no problem. Operation in VOX mode proved to be more difficult. Theoretically, the device then recognises speech, opens the channel automatically and releases it again as soon as there is no more speech. The other person can then answer. In practice, however, wind noises (there was only a very slight breeze) or rustling clothes are enough to open the channel. However, this means that the channel is busy for the other device.
The sensitivity of the noise detection can be adjusted, but that hardly helped. If it still worked, the radio usually swallowed the beginning of the sentence, as it first has to identify the noise and open the channel, and that takes some time. That's why it can be useful to start every sentence with a long "erm". That way, no information is lost. However, a normal exchange does not take place. Even with the Simvalley headset, this fundamental problem did not change.
According to the instructions, the Retevis radios can also be switched to VOX mode, but this is probably only possible with a connected PC and not via a key combination.
Significantly smoother communication is therefore possible with headsets, among other things, which we also offer. have recently tested. However, these are dependent on the mobile phone network in connection with the smartphone (via call). PMR radios are generally cheaper and independent of the mobile phone network. They are also suitable for keeping in touch with children who are on a dinghy trip. With the walkie-talkie models from Motorola and Retevis, there is also no need to worry about possible contact with water. The devices are well protected and very robust. Operation is super simple. What's more, any number of additional devices can take part in the communication if you have a large crew.
PMR radios from Simvalley are inexpensive, with a set of two walkie-talkies starting at just 40 euros. However, the radio systems from Motorola and Retevis impress with better protection against the elements, the former even floats. That is why we have awarded five stars here. For just over 100 euros, the models offer good value for money.
There is no doubt that the robust and proven radio technology of walkie-talkies can be helpful. The short reach for the PTT button does not always have to be a hindrance.
Tests were carried out under realistic conditions, on board during harbour and anchor manoeuvres.
The name says it all: H2O indicates that Motorola's PMR radios are made for water sports enthusiasts. They are waterproof to IP67 standard, float and have an emergency light that activates on contact with water. This increases the chances of finding a walkie-talkie that has gone overboard, even in the dark. The VOX mode does not work reliably, but otherwise it's great!
The PMR walkie-talkies from Retevis come in a very robust and minimalist design, so there is no display. Selected channels are communicated by voice output. This makes operation somewhat less intuitive, but still works well. Technical data The devices are waterproof in accordance with the IP67 standard. A headset with proprietary connection is available, as is a VOX mode. Practical: charging station with USB.
Attractive price, but also a few disadvantages: Simvalley's walkie-talkies are not waterproof and are not rechargeable. Each device is powered by three AAA batteries. The WT-320 worked well in the test. They offer an LED light, a connection for headsets and a VOX mode. However, ambient noise activates the channel unintentionally. A hand on the button is therefore necessary.
Slightly higher price than the almost identical WT-320 devices, but also some added value: The Simvalley WT-330 has rechargeable batteries and can be charged in a station on shore power. Otherwise, there is no difference in functionality. Both Simvalley models are very handy compared to the other test devices. They can be attached to clothing using a clip on the back.
