Radar is mainly used for collision-avoidance and thus contributes towards safety at sea. However, it only brings benefits to skippers who are familiar with the principles, functions and its limitations.

This one-day course is ideal:

  • As an introduction, for those just wanting to know what Radar is all about
  • For sailors thinking of buying a Radar, but needing support in their decision-making
  • For yachtsmen who already have Radar onboard, but are not familiar with all the functions.
  • A course notebook is included.
    Our Instructor has combined his many years at sea in the British and South African merchant navy, together with 25 years in the radar industry, to present a realistic and easily understood radar course.

    If any of the course dates or venues are unsuitable for you, then please contact us.

    We take pride in being a very flexible training centre, so can offer you the following:

    • A course in your vicinity, on a date that suits you
    • A course in your sailing club
    • A one-to-one Radar training session, either in your vicinity or here in our training centre, where you can choose the agenda.
    • A course either in English or German

    Our Radar courses in Geneva are held in English. The courses at all other venues are held in German.

    Our Radar courses are supported by:

    Raymarine, Deutschland
    Werner Ober, Österreich
    Yachtech, Schweiz

    A video-beamer and laptop is used to present the following subjects of the theoretical part of the course:

  • Basic principles: Principles of function; typical terms; wave propagation
  • Components of a radar set: Main components and their functions; practical safety
  • Resolution: Features that influence the picture (e.g. horizontal beamwidth, pulse-length, pixel)
  • Targets: Target-characteristics; reflectors; RACONs; RTE (Radar Target Enhancer).
  • Display modes: Head-up; North-up; Course-up; Off-centre; True motion.
  • Navigation: Various methods of plotting your position using radar, e.g. bearing, range, etc.
  • Collision Avoidance: calculating CPA, TCPA, course and speed of a target; MARPA;
  • The Radar-relevant IRPCS rules.

  • During the practical part of the course, numerous Raymarine E120 display units (see picture) will be available, where participants can practice the following:

  • Switching on: The main controls; picture-interpretation; other useful controls; optimising the picture.
  • Navigation: Various methods of position plotting, e.g. bearing, range, etc.
  • Collision avoidance: MARPA; Calculating the CPA, TCPA, course and speed of a vessel; AIS; practical use of the Coll-Regs (IRPCS)
  • Additional Radar functions: Cursor; Auto Gain/Tuning; Wake; Guard Zones; Evaluating Data Boxes; timed transmit; etc.
  • Additional displays: Plotter, AIS, GPS, Echo-sounder, Radar-Overlay, etc.


    And finally - would you know the answers to the following:



    You are in dense fog. There is another vessel in your vicinity that you can only see on your radar screen. Who has right of way now, (according to the Coll-Regs?).
    Could the radar picture (on the right) be optimised? 
On the radar course you can try it yourself.
    How would you know if the blob on the screen is a buoy or a ship?
    Can you make your yacht more visible for other vessels?
    How do you calculate CPA, TCPA and speed of another vessel?
Can MARPA do this automatically?
    Which controls must be treated with extreme caution?
    Which IRPCS rules are radar-relevant?
    All these subjects – and many more, are dealt with during the course.
