Technical & theoretical aspects of RC yacht racing

Updated December 2013

I'm interested in radio-controlled racing yachts, in particular the International One Metre (IOM) class and the International (now "Classic", I guess) A class.  I campaign a Pikanto IOM, a Sword "A", and now a 1997 Ten Rater "Puzzle" (chartered from SAILSetc), all designed and built by those super-professional folks at SAILSetc.  For some years I campaigned an Italiko IOM, and before than an Ikon.

My "Bakers Dozen" A Class, built by Graham Bantock in Kevlar to Roger Stollery's design from 1983 and the RA National Champion of that year, has returned to my garage after being cared for and re-painted and faired by Derek Kitchener.  She is ready once again to go to a good home, send me an e-mail if you are interested.  "lg11" at "soton.ac.uk".

This site is aimed at technical and theoretical aspects of RC yacht racing. In particular, it has a number of spreadsheets to download. Although aimed at the IOM, they should be useful for any non-rotating fractional Bermuda sloop rig.

These pages are intended for educational purposes.
My education particularly (smile), but I hope you find them useful too.
If you'd like to reprint, copy, or link to anything, go ahead,
but do please attribute my words, diagrams, photos,
 spreadsheets, and software to me so others know who to blame.

Site news & other interest

December 2013:  Graham Bantock and I have thrown our hats into the ring for the IRSA Executive Committee Elections 2014.  We'd like to hear from anyone who would be interested in joining us, and we welcome your comments, either publicly or privately.


Site content

My additions to the site content are now more episodic than regular, so I thought I'd reorganise the site into better sections to recognise that it is now much more static, and to help newcomers access its content.

The material has been classified into the three major headings of Design, Build, and Race.  Anything not fitting that scheme goes into Other Topics (except for Links and Reports which have a place on the main navigation bar).

Under Design are pages on How a yacht works, How aerofoils work, Where lift comes from, How fins and sails work, Appendage design, Hull design, Sails and rigging design, and The boat as a whole.

Under Build are pages on Hull, Fin & rudder, Bulb, Sails, Rigs & fittings, R/C, and Finishing off.

Under Race are pages on Preparation (Boat speed, Avoiding errors, Strategy), During the regatta (including topics on the racing rules), In the race (Boat speed, Avoiding errors, Tactics), and Performance improvement.

Other Topics include pages on International RC racing, Classes, Sailing venues, Event management, Event scoring, Observing, Ancilliary equipment, Bulb calculator, Plans, References & book list, and Terminology.

Commercial stuff

I've developed sticky-backed gauges that can be purchased from SAILSetc.
I publish Larry Robinson's booklet on making model yacht sails using blocks, also available from SAILSetc.

The (fourth!) counter died in early 2012.  So I've given up on a counter.

Some site statistics instead: approx 300 pages, 2400 images, 40 spreadsheets...

(The first counter logged around 86,000 hits from site inception in early 2003.  The second counter took over in August 2003, and died at around 160,000 in mid-July 2006.  The third counter died with around 170,000 hits in early February 2010, and the fourth terminated in February 2012 with 85,000 hits recorded.  So that's a total of 500,000 over 9 years...)

For some curious reason, you're all finding the site interesting!  Many thanks!
