Technical & theoretical aspects of RC yacht racing Updated March 2025 I'm interested in radio-controlled racing yachts. I campaign a fine wooden hulled
Ravenna in the UK 6M class, shortly to be joined by an equally fine Romanza,
both Bantock designs. I have acquired a 36R Raptor and sail it
approximately annually. For some while I sailed in the International
One Metre (IOM) class, most recently with a Pikanto,
and hope to return 'real soon now'. Previously I campaigned an Italiko
IOM, and before that an Ikon,
highlights being various mid-fleet placings at European and World championships.
In other classes, I have sailed a Marblehead Quark, a 10R Puzzle, and
vane-sailed an A Class and a 36R. For some years I also campaigned a Sword
A Class, my highlight was 9th place in the
World Champs at Gosport in 2005. 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 gone to a good
home in Norway, courtesy of
Øyvin 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.
Site news & other interestMarch 2025: Some pages in Other Topics illustrating the construction and use of a flotation tank and dry measurement jig for 6M boats with 3D printed equipment where possible, starting with 6M tank and jig construction, establishing 6M Waterline endings in the tank, 6M boat in dry jig preliminary measurements, Stern station measurements, and Bow and girth station measurements. March 2025: Some sailing events seem to have increasingly bad-tempered bickering over incidents on the water. I thought a short 2-minute welcome from the Chair of the Protest Committee might help to lower the temperature. Site contentThe material is 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). Other Topics include pages on International RC racing, Measuring, Classes, Sailing venues, Event management, Event scoring, Observing, Ancillary equipment, Bulb calculator, Plans, References & book list, and non-sailing-related pages on Alphard camper-van picnic units, Photography, Duplo train track layouts, Statistical analysis of data using analysis of variance, and biographical recollections. Scans of some International Radio Controlled Model Yacht Championship programmes and results are in Gosport 1975 (plus an article on Radio sailing history by Norman Hatfield), Durban 1978, Ottawa 1980, Dunkerque 1982, Ullnasjon 1983, Gothenburg 1987, and Berlin 1988. Articles originally published in the American Model Yachting Association's (AMYA) excellent "Model Yachting" magazine are now reproduced on the site by permission of the Editor.
