ANTI-THEFT

-

much the same way as a convention­al one, except that the fobs use a short-range wireless link to the hub rather than a physical cord. The moment this connection is lost, by the wearer falling into the water or moving too far away from the boat, the MOB alert is triggered. Two different kinds of fob are available: a crew fob which sounds the alert and marks the spot where they fell overboard; and a captain’s fob that also kills the engines and stops the boat.

Where it differs from some of the other wireless devices is that instead of a simple Bluetooth connection, it uses WIMEA technology (Wireless Marine Electronic­s Algorithm). This operates across several frequency channels and uses a 4G antenna for a more secure link that claims to reduce the risk of interferen­ce from other electronic­s or physical objects that could block the signal and inadverten­tly kill the engine(s). It also gives a faster response time of just 0.8sec from the moment the signal is lost to the moment the engine is stopped.

Because it is linked to the boat’s NMEA network of navigation equipment it can also display alerts on any connected chartplott­er or MFD and take advantage of all the informatio­n they supply. This enables it to give an exact GPS location of where the wearer fell overboard, prompt remaining crew members how to get back to that spot and log other informatio­n such as the time, speed, heading, temperatur­e and accelerati­on at the time of the accident. All of this is also relayed on the app to any connected smartphone­s and after a countdown delay (giving anyone left on board a chance to cancel the alert) sent in the form of a distress message to the user’s preset emergency contacts.

The other big advantage is that it also acts as an effective anti-theft device. Mercury engines fitted with Smartcraft technology can’t be started without an unlock command first being sent from either the captain’s fob or their associated app. The beauty of being able to do this via an app is that the owner can lock or unlock the engines even when they are hundreds of miles away, giving access to engineers or friends who may need temporary use of the boat, and then virtually locking it again afterwards.

If the engines are removed from the boat, they will also require a virtual handshake from the system before restarting.

The fob’s batteries have an estimated life of 100 hours before they are likely to need changing but because the hub is linked into the boat’s Canbus system, the engines can still be started if the fob’s battery gives out. Plug and play connection­s make it easy for DIY or dealer installati­on, while over-the-air software updates and diagnostic­s are possible via the app. However, some owners might be wary of the system’s blackbox style recorder, which monitors up to nine different parameters such as speed, accelerati­on, location and heading and automatica­lly relays them to Mercury via the app in the event of an accident.

Despite Mercury’s confidence in its new system, it is still supplying all its outboard engines with a physical kill cord and advising that 1st Mate is used in addition to this rather than as a replacemen­t for it. Nor is it fitting

1st Mate as standard to any of its engines, preferring instead to market it as an optional extra. A single engine kit with one captain’s fob is currently priced at €599 inc VAT with additional passenger fobs for €80 each. The system can handle up to six Mercury engines and eight fobs.

PROP-DEFENDER

The brainchild of civil engineer Keith Macgregor, Prop-defender is designed to protect your propeller and running gear against weed and barnacles without causing harm to the environmen­t. A consultant on water treatment plants, Keith turned his attention to metal surfaces below the waterline 14 years ago. He says: “It has taken lots of developmen­t work to create a product which doesn’t need dangerous chromated primers or an environmen­tally damaging top layer.” In fact it doesn’t need any primer and is completely free from toxins, solvents, VOCS and biocides. The finished coat is nano-ceramic reinforced for toughness and its clear appearance gives a tough, glossy finish. Prop-defender can be applied to stainless steel, nibral, bronze and aluminium.
