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.

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.

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.
Mounting
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.)
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.

The NASA Stingray Echo Sounders come in a slimline case with an easy to read extra bright LED display on a 4 inch dial. They both have a dual audible alarms for shallow and deep water which can be set to give two ranges either 1-25 metres or 1-100 metres, and are simplicity itself to operate. They come complete with transducer and stirrup mounting bracket and only require connection to the ships 12v power supply.
Sadly, as some component parts have been increasingly difficult to source this product is no longer in production. Anyone who has one can fit any of our digital depth sounders to the same Stingray depth transducer.

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.
