Additional Information
International Regulations for Prevention of Collision at Sea require that you keep watch by means of radar if it is fitted on the vessel and operational.
Radar can be the most useful navigation instrument on the boat, but if you are not sufficiently familiar with operation of the controls and interpretation of the radar picture, it can mislead you into potentially dangerous decisions.
A major benefit of radar is it is completely self-contained. You are not dependent on marine authorities maintaining buoys, or other vessels operating AIS identification systems.
All controls function just like real equipment
You operate radar controls & navigate your vessel
You can edit or create new scenarios at will
There are no fixed displays or pre-recorded video (except in the helpful tutorials)
Radar Controls
Power : Switches the radar set on or off
Standby / Transmit : Toggles the transmitter electronics on or off
Range Selection : Select distance represented by the radius of the screen
Rings On / Off : Hides or shows the Range Rings
Heading Mark Suppress : Temporarily hides the Ship’s Head Mark
Head Up / North Up : By default, the top of the screen is aligned with the ship’s bow. North Up rotates the display to put North at the top.
Electronic Bearing Line : A line from centre of screen to the edge, which can be rotated to read off or indicate a particular bearing.
Variable Range Marker : A circle of variable diameter around the centre of screen, to set or measure a particular range from your vessel
Wakes : Turns the Wakes function on or off, displaying a ghost indication of previous positions of all contacts
Interference Rejection : Switches in a circuit to prevent a distinctive spiral pattern resulting from interference from another vessel radar
Target Enhance : Slightly enlarges the image of all contacts, to make small contacts easier to see
MARPA : Mini Automatic Radar Plotting Aid which can calculate and display the direction, speed and other data of selected contacts
Cursor Position Control : A rocker pad or joystick to move the cursor around the screen and display range and bearing of selected contacts
Brilliance : Adjusts the overall lighting of the whole screen
Gain : Varies the amplification of returning echoes. Adjust to minimise noise speckle while retaining weaker contacts
Tuning : Adjust to match receiver frequency to exactly that of the transmitter
Sea Clutter : Adjust to minimise reflections from waves, while retaining weaker contacts
Rain Clutter : Adjust to minimise reflections from clouds and precipitation
Controls listed are for Green-screen set. LCD set has more functions but fewer physical controls
Radar Displays
Plan Position Indicator : The main display of contacts, including coastline, around your vessel
Own Ship Heading and Speed : Shows your current heading and speed through water
EBL and VRM : Angle of Electronic Bearing Line and Distance of Variable Range Marker
Cursor Bearing and Range : Bearing and Range from own ship to cursor position
Tuning : A bar-graph indicator to assist setting correct tuning
Range : The distance represented from centre to edge of the display
Rings : The distance represented by spacing of range rings
Head Up / North Up : Current orientation of the display

What They’re Saying
Customer Testimonials
I will be taking a Coastal Skipper practical course next month. I was concerned that I had never used radar before, but the LightMaster Radar Simulator has given me confidence that I will be able to demonstrate competence with the radar during my course.
We have used a LightMaster Radar Simulator as a central plank in our RYA Radar Course for several years. During lockdown it enabled us to run courses over Zoom, with each student having their own Simulator to run at home.
Wow! I’ve had such enjoyment getting into navigation with the radar software. My new cruiser will have a full electronic nav system, but I would not have been able to use it to the full without this great program.
