Now, as the old saying goes, you pay your money and make your choice. Which of course can be as critical as doing something else, depending on the situation. In fact, even if I don't think it's specified in the instructions of the boat devices which are being discussed, that's exactly how they also work.īottom line, if you are reversing into your berth, there is ALWAYS the possibility - unlikely as it can be - that in the very moment when you want to engage the fwd gear to stop the boat, due to some interferences, the receiver doesn't get a clean signal and therefore does nothing at all. In other words, it can happen that a crane receiver does not get a clean signal due to some interferences, and the only logical behaviour that the engineers can program in these devices for handling this occurrence is that the crane does nothing at all and remains in the same status. But, there are no ways known to mankind to be always 100% sure that the received DOES understand the signal sent by the transmitter, and acts accordingly. This is the good news, and the reason why there are wireless devices rated for critical industrial applications: accidents due to the fact that a heavy crane operator sent a "lift" command with the transmitter, and the crane actually lowered its load instead, are unheard of. There are very safe ways to avoid the receiver doing something different from what the person with the transmitter meant to do - at least with a well designed device built with quality components and embedded redundancies, as the YC is. Click to expand.Just take this FWIW, but it's something I learnt from an engineer involved in the development of these devices for industrial applications - hence arguably even more critical than for pleasure boating.
