Electromagnetic Log – speed through water – with no moving parts!
The EML-2 electromagnetic speed log measures the boat speed through the water with no moving parts.
Robust and accurate, the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water.
With excellent linearity and a resolution of 0.1 Knot, over the range 0.2 to 40 Knots, the control box converts the sensor signal to boat speed, trip and total distance and sends it to any compatible NMEA-0183 display.
For a complete solution the EML-2 electromagnetic transducer and controller can be supplied together with either a
or a
or to a
NMEA 2000 backbone via our converter
EML -3 is a pulse output version of the Electromagnetic Log to suit any previous NASA Marine paddlewheel log including all Target, Clipper Logs and Duet. Also works with Raymarine ST60 Log display.

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.
Liquified petroleum gas (LPG) is an invaluable source of energy on many sailing vessels. It should, however, be used with great care. In its gaseous form it is heavier than air and will always collect at the lowest level in a vessel. Any leak of gas, any spillage of liquid could sink to the bilge and, unable to escape, build up to explosive proportions.
The NASA Marine gas detector system warns if the level of LPG rises above 10% of the lowest explosive limit (LEL) giving adequate warning of the need to ventilate the area before a dangerous situation occurs. The system consists of a cabin mounted monitor and a remote sensor. The monitor gives visual and audible warning if gas levels at the sensor rise above 10% LEL and will warn of fault conditions such as damaged cables etc.
The splash proof sensor is supplied with a 5 metre cable and has a test button to check the system right through to the gas sense element. The sense element is user replaceable in the event of contamination. Supplied with power cable.
The Target electromagnetic speed log measures the boat speed through the water with no moving parts.
Robust and accurate, the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water. It is designed for installation into most types of GRP hulls.
With excellent linearity and a resolution of 0.1 Knot, over the range 0.2 to 40 Knots, the log sensor sends signals to a control box which then converts the sensor signal to boat speed, trip and total distance. This data is transmitted in NMEA 0183 format to a new Target EM Log display unit.

Electromagnetic Log – speed through water – with no moving parts! It will replace most conventional paddle wheels from all manufacturers!
The EML-3 electromagnetic speed log measures the boat speed through the water with no moving parts.
Robust and accurate, the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water. This signal is converted to a pulse stream to replace any existing paddle wheel sensor.
With excellent linearity and a resolution of 0.1 Knot, over the range 0.2 to 40 Knots, the control box converts the sensor signal to a pulse output to connect to any NASA Marine paddle wheel log display (Clipper Duet, Clipper Log, Target Log, Stingray Log)
Technical Info
Pulsed output to replace exsiting paddle wheel unit
Pulses per nautical mile adjustable from 15000 to 25000 PPM
Output levels – High 5V P to P
Low 0.5V P to P
(note – the transducer is a low profile unit, the 50mm OD skin fitting included
will need to be fitted in place of your current fitting)
For a complete solution the EML-3 electromagnetic transducer and controller can be supplied together with a Clipper Duet

A large display, mast mounted, multifunction repeater is now being produced at our factory. The weatherproof repeater with its 60mm high numerals, is supplied complete with cables, data-box with six NMEA-0183 inputs ( With up to six sentences per input.), wireless remote control, stainless steel mounting brackets and weather cover. There are nine levels of red back lighting which permit easy night viewing of red characters on a black background. The overall case size is 211mm wide x 140mm high.
Currently programmed in are the screens shown below though we do welcome customer feedback as we will add to this list by popular demand.
TARGET HF3/P & HF3/W
The Target HF3 is a masterpiece of R. F. engineering covering the entire spectrum between 30Khz to 30Mhz. For those new to single side band reception the unit comes complete with everything needed to ‘get on the air’ including a comprehensive instruction manual which includes a list of useful marine frequencies.
Controls on the front of the receiver change reception mode, from a narrow filter for SSB reception to a wide filter which enables high quality audio signals to be heard from broadcast stations around the world. They also control ten memory channels to store your favourite frequencies.
The large, clear liquid crystal display shows the precise frequency tuned to and there is no need for constant ‘correcting’ with the tuning knob so often associated with SSB signals as the receiver
is fully synthesised.
TARGET HF3/P
The Target HF3/P has a fixed level audio output to connect to third party weatherfax software. The receiver is supplied complete with a basic long wire antenna, 12 volt power cable and instruction book.
TARGET HF3/W
The HF3/W is complete with CD software and interface cable for connection to a PC sound card. The software enables reception of weatherfax pictures, Radiotelex weather forecasts and Navtex. Simply install the software, plug in the supplied cable to the receiver output and PC sound card to receive weatherfax pictures and forecasts from around the world.
Requires PC Windows XP to 10.
All instruments in the Target Range come complete with sensors or transducers as appropriate and all necessary fittings. They are designed to run on 12v supply, but due to the very low power consumption there is no reason why they cannot run off dry batteries. They provides accurate readings for owners of sailing craft and powerboats alike. Following the NASA design philosophy, the Target Log is simple and reliable showing speed in knots, trip distance to 999 nautical miles and total distance run up to 999 nautical miles.
The Target Log is supplied with a through hull paddle wheel unit designed for installation on most GRP type hulls.
The Clipper electromagnetic speed log measures the boat speed through the water with no moving parts.
Robust and accurate, the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water. It is designed for installation into most types of GRP hulls.
With excellent linearity and a resolution of 0.1 Knot, over the range 0.2 to 40 Knots, the log sensor sends signals to a control box which then converts the sensor signal to boat speed, trip and total distance. This data is transmitted in NMEA 0183 format to a Clipper EM Log display unit.
