Technical & theoretical aspects of RC yacht racing

Updated August 2015

I'm interested in radio-controlled racing yachts, in particular the International One Metre (IOM) class, where I campaign a Pikanto.  I've taken up vane sailing as crew for Anthony and assist with his A Class and his 36R.  For some years I campaigned an Italiko IOM, and before that an Ikon.  Until recently I also campaigned a Sword A Class.

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.

Site news & other interest

August 2015:  After many years of prototyping and development, I've made a Limited Edition batch of a variable "V" spreader to suit the IOM.

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.
I've manufactured a Limited Edition adjustable spreader that, until stock runs out, can be purchased from SAILSetc.
