Official organisations

  • The UK MYA site has the events calendar for the UK and the current national ranking positions.
  • IRSA is the radio sailing international authority for scoring systems, class rules, sailing instructions, regatta management, and so on. (*)
  • World Sailing is sailing's international organisation for the racing rules of sailing, the equipment rules, regulations concerning international class associations and the recognition of International yacht classes, and so on.
  • IOMICA is the official class association for the IOM. Its Web site gives key information about the class and its international class association, documents, and links to national class associations.
  • The AMYA publishes 'Model Yachting' quarterly, a superb publication the envy of the model yachting world.


  • Ken Binks runs K.Bits.., offering his great wealth of RC experience to go with sales of RC gear and fittings. His site has useful tips on RC gear.
  • I use RMG winches with SAILSetc sails.  The SAILSetc site has a useful FAQs page for both the newcomer and the established skipper.
  • Model fixings provides radio control modellers with a source of 'engineering parts' (UK).


  • IOMICA runs an IOM Forum as a discussion group. Why not join it if you are an IOM owner?  Hear official, semi-official, and unofficial news and opinions, and offer your own.
  • Serious technical discussion at the Boat Design forum oriented towards full-size.



  • The Vintage Model Yacht Group has a very nicely presented Web site.
  • Martin Hepperle's site is a must-browse if you are interested in aerodynamics.  And he has the definitive history of the Cox engines that I loved as a kid.
  • The WB Sails site, although aimed at dinghies and "big boats", has much to interest the model racing skipper.
  • Lots of aerodynamics links at Prof Selig's page. Follow up on Ken Blackburn's superb site for paper planes at least!
  • UK Sailmakers have some delightful software. Give it your (digital) sail photo and it reports the vital statistics: camber, position of maximum draft, relative twist. I show the software in use on my "Measuring sail photos" page.
  • Instructions for the SAILSetc gauges.


These are links that catch my attention. They'll change from time to time as I find new sites to feature and old sites to retire.

  • At Cape Town, many years ago, Angelo Lavranos very kindly sketched me a beautiful Marblehead design. I failed miserably to make a go of it because of my poor building skills, while Angelo has gone from strength to strength as a "real" yacht designer. He has a Web page.
  • The Amateur Yacht Research Society (AYRS).



(*) The International Radio Sailing Association (IRSA) says that it "represents" the Marblehead, Ten Rater and A Classes.  In fact, it acts as the Class Association for these classes.

On the run

Well, it was a good start, at least...

On a broad reach in B rig

Drifting:  you can see the large wind gradient

Yup, she's OK...
