Tactical Wind Mast Sensor (NMEA)
A high performance system that sends NMEA wind speed and direction data 10 times a second.
In demanding conditions, where high performance is essential, the Clipper Tactical wind mast sensor is the ideal choice. With ten updates every second it responds very quickly to the changes in wind speed and direction, which occur during tricky manoeuvres. The sensor is supplied complete with a mast mounting kit, 20 metres of light weight cable and all necessary electrical connectors to complete the installation. The output data is in the NMEA 0183 format and can be used to drive any compatible display that utilises the MWV sentence. Supplied as standard to Clipper, Target and Cruiser V2 wind systems.
NOTE – This 3 wire NMEA mast unit is not compatible with earlier 5 wire analogue Clipper, Target or Cruiser wind systems. The earlier analogue mast sensor is available on the spare parts page.
- Mast transmitter supplied with 20 metres of cable
- NMEA 0183 4800 Baud data sentence MWV – update rate = 10 per second
- Wind speed 0 to 99.9 Kts
- Wind direction 0 to 360 degrees
- Supply voltage nominal 12 Volts
- Wind sensor supply current 9mA
AIS Engine 3 upgrade processor
The AIS Engine 1 and 2 can be upgraded to AIS Engine 3 specification by replacing the processor. This is a straightforward procedure where the old device is simply unplugged from its socket and replaced by the new device. AIS Engine 3 relays all AIS messages.
EASY LIGHT LED Luminaire
The NASA Marine 12 Volt Easylight luminaire contains 48 high efficiency LEDs in a slender surface mounting package.
The cool white version (CW) is recommended where maximum illumination is required and the warm white (WW) where a more natural light is preferred. Light output for the (CW) is typically 300 Lumens and typically 250 Lumens for the (WW).
The unit is designed for surface mounting directly on a ceiling or wall using the screws provided. It is not waterproof and is intended for use in a dry cabin only.
When fitting ensure that the ventilation slots are not obstructed and take care not to over tighten the screws. When in operation the space behind the unit may get warm so avoid mounting on surfaces where this could cause a problem.
The power leads can be taken through a convenient hole in the mounting panel or alternatively through one of the end vent slots. Connect to a 12 volt DC supply via a suitable switch and a 1 Amp fuse. The red wire goes to the positive supply connection and the black wire to negative. (An internal diode protects the unit against supply reversal.)
H Vector Navtex Antenna
Conventional navtex antennas respond to the electrical component associated with the navtex radio signal. They usually perform well at sea where electrical interference is low but can sometimes be overwhelmed with interference especially when in harbour and connected to shore power.
In most small craft the electrical system acts as an effective ground for the antenna but it can also be a source of interference conducted from other electrical equipment on board. Electrical interference can result in poor reception especially in a marina where the ambient level is high or at sea when poorly suppressed electrical equipment is in use.
The omnidirectional H-Vector antenna is not sensitive to electric fields but to the magnetic component of the navtex signal. As a result it is less sensitive to locally generated interference and, as it does not need a ground, it is not affected by conducted ground interference whether in harbour or at sea.
The net result is that, under adverse conditions, the H-Vector antenna can deliver a significant improvement to navtex reception. The mushroom shaped antenna is compatible with the Clipper navtex, series 2 Target navtex and with the navtex engine. It can be mounted on a cabin roof or rail mounted using an appropriate threaded antenna base.
I am delighted with our new antenna. Our Navtex , normally somnolent in the marina, has burst into life!
Someone asked me recently – why bother with Navtex? My answer was simple. Last year a gale blew up suddenly on the Turkish Aegean coast. The Navtex transmitter at Izmir issued an urgent gale warning out of ‘normal hours’ and it was the only service to do so! For example there was nothing about this gale on PredictWind on our WiFi.
Now had a full month on the boat in Turkey cruising around and am even more delighted than ever with the new antenna!
