Where might we go from here.
My first thought was to simplify the measurement of an IOM, and thus to simplify the class rules. After a couple of years of trying to simplify the rules, I realised they were about as simple as they could possibly be and still achieve a "home-build one-design". [Yes, indeed! For those doubters out there, I invite you to have a go yourselves at simplifying the IOM rules and still end up with essentially the same boat. Jan always reminds me that the apparently "simple" IOM class is achieved by "complex" rules. There seems to be something of an inverse relationship between the "simplicity" of a class and "complexity" of the rules.] The idea, of course, is to maximise the appeal of the class to the club skipper, to encourage its increased adoption in countries where it has not yet achieved a significant position, and to minimise regulatory and measurement problems and overhead. I now think that the IOM class association should introduce an IOM design which is a strict one-design hard-chine hull (the Boxkite is on offer from Graham Bantock) with materials restricted to wood only in both hull and appendages. This kind of IOM would use "normal" measured IOM rigs and sails, but ball-raced goosenecks or jib swivels would not be permitted. Using an idea of Charlie Coventry, whenever this kind of design races with other IOMs, the other IOMs would have 2 points added to their score in every race of that event. We might call this kind of IOM the BOM -- the Box One Metre and provide it with its own class rules.
Following this idea, and taking it one step further, is to introduce a "manufacturer" IOM. This design would consist of a complete kit of materials and fittings, needing only radio control to go racing. Its rules would be very simple -- you can use only what is in the kit, and you have to use it the way the kit instructions say. This would be the MOM class, and it would have its own class rules.
My second thought a while ago was to improve the standard of sailing at IOM events. We now have umpiring at International events, and this I think is an excellent development. So my second thought now is to give experimenters and tinkerers a class to play in as well -- a "Marblehead" IOM, if you like. So I think the IOM class association should introduce a kind of One Metre, where there are no restrictions on materials or fittings, while keeping the "normal" IOM length, weight, and overall draught limits for a mono-hull, and the "normal" IOM dimensions for the sails. Everything else is "free". Extending Charlie's idea, every such "unlimited" One Metre would have 1 point added to its score when racing. We might call this kind of One Metre the FOM -- the Free One Metre, and again provide it with its own class rules.
While the BOM and MOM could measure as an IOM, the FOM obviously would not. The FOM's attraction is that it conforms to the IOM "core" idea -- a minimum displacement in a one metre length with standard size sails -- while allowing itchy fingers and enquiring minds to enjoy freedom... Neither the BOM, MOM, nor the FOM would be "International" classes, but who knows what time might bring us if boats were built and raced in these classes around the world? It might be worth being clear that none of these ideas actually affect the IOM class and the IOM class rules -- these continue exactly as they are. If you are interested in reviewing and commenting upon the proposed BOM, FOM, and MOM class rules, e-mail me and I can send you a document.

A welcome from the IOM ICA Executive Committee
It is my honour as one of the youngest IOMICA Executive members to address you on behalf of our newly elected Executive Committee. Like you, my passion and commitment for this brilliant global class have only strengthened with my growing participation. It is fitting having this address come from one of our youngest members, as more than 50% of our electorate is new to the Executive Board. So, to initiate this address, I would simply like to start by pausing to thank each and every one of you. Thank you for your support and participation in a radio sailing class that has origins dating back to 1958. What an accomplishment! This lengthy tradition has produced some amazing sailboat designs and memorable events year after year. The shared passion for IOM has generated a global camaraderie that unites us all. Recognizing this, we would like to acknowledge some remarkable individuals for their stalwart commitment and personal sacrifice in promoting our IOM Class and the infrastructure behind it.
We must congratulate Mr. Fred Rocha for his eight years of service as the IOM ICA Chairman and acknowledge everything he accomplished. His perpetual enthusiasm and inclusivity are traits that have greatly benefitted our class. He aspired to improve both our internal and external communication, promote the development of our class in new territories, and openly embrace new concepts and ideas. Fred was very generous with his time and support of all our organizational requirements, and worked tirelessly in this pursuit. Congratulations also need to be extended to our newly elected IOM ICA Chairman, Mr. Olivier Cohen. Additional changes in the Executive resulted in the position VC – Technical is going from Mr. Jeff Byerley to Mr. Robert Grubiša, VC – InfoComms passes from Mr. Pedro Egea to Josip Marasović, and the position of Treasurer formally transferring from Mr. David Turton to Mr. Sean Wallis. Pedro Egea deserves special recognition, as he’s tirelessly served our group with IT and “common sense” support for now eleven years — you are a genuine rockstar!! VC Measurement position is vacant, but we wanted also to congratulate Mr. Lawrie Neish, a true veteran who was helping us for around 11 years!! Gentlemen, you all deserve our heartfelt thanks for your service, and be assured we will raise a glass on your behalf.
As COVID continues to be a present challenge for all of us, I’d like to conclude this greeting with a note of enthusiasm . Always remember why the IOM Class is held in such high esteem in so many different countries, surviving the test of time! No matter how technologically advanced and exceptional IOM sailboats become in future, we will always rely on an overwhelming and continued desire to explore all facets and possibilities to improve performance and everyone’s experience in the end. We need to continue to push our limits in all sectors of this class, and convey that information in an open and democratic fashion. This voice needs to be expressed beyond just our annual vote, but vocalized at every race, regatta, start, and buoy rounding, and literally every metre moving forward. Whether you are sailing at a top international regatta or having a twilight club race with friends, you are all part of this active global IOM family . We are all facing challenges and uncertainty in our daily lives, but we do not have to question our passion and commitment to IOM. Through your individual activities and support, each of you is responsible for helping make this class what it is now and will ultimately become. Our growth and transformation evolve only when you participate , experiment , and continue to explore , so your engagement is crucial to our success in the future. We look forward to seeing you at future regattas, active in our forums and chats, social media and in photos. The year 2021 is at the very end, but we are just getting started, so let us all continue our story together .

Click the picture to get to the boat's page The IOM Class The International One Metre class was created by Jan Dejmo, with the support of Graham Bantock and the Permanent Committee of the ISAF-Radio Sailing Division, and adopted by ISAF-RSD in 1988. The intent was to pull together a variety of "One metre" class rules from different countries, and provide for a common, restricted, inexpensive international class of stable, easily-built designs. The result is the most popular RC racing yacht class in the world. The class has enjoyed such success because competitive IOMs can be built by an ordinary modeller at home, and due to the class restrictions competitive boats remain competitive for a number of years. IOM rules The performance of a RC yacht depends on hull lenght, beam, displacement, sail area, bulb draft, ballast ratio and rig plan. The only parameter than can be freely changed is the beam, all others are restricted by the IOM class rules. Therefore it is primarily differing beams and positions of maximum beam, which distinguish the different IOM designs. In addition to performance factors, the class rules explicitly restrict certain materials and construction methods in order to keep the class inexpensive and able to be built by an amateur builder. Radio control is restricted to two channels. Appendages and sails can be made of any material. A competitive boat can be built at home.
International One Metre
The International One Metre (IOM) is the most popular RC racing yacht in the world and is raced in over 30 countries.
The class was created in 1988 by Jan Dejmo aided by Graham Bantock and the Technical Committee of the IMYRU (predecessor of IRSA). It has continued to grow steadily since its creation.
Although carbon fibre is allowed in the construction of the fin and rudder, construction of the hull must be of either wood or glass fibre. Spars shall be of alloy or timber and the sails are to 'One Design' sizes.
The number of rigs is limited to three. This makes the class very popular for amateur builders and many designers have plans for competitive boats. Builders who can supply kits for home completion or completed boats are plentiful.
The IOM class is managed by its own International Class Association, the IOMICA. Please visit the class website at www.iomclass.org

Frank Russell Design
R/c and model yacht design, plans, boats, sails..
I have been a designer of model and radio yachts since 1968. Boats been built from my plans now number in the hundreds both from both home and production builders. Many of my designs have won State and National Championships in Australia and overseas. New designs are added periodically and occasionally I do receive requests for specific designs. I also from time to time produce free plans.
Most of my older plans Pre 2000 will eventually be available as PDF files of the original large format drawing. The plans are located here:
A more complete list of my designs is here:
Plans are normally drawn on A4 and A3 format. Sections and appendages are normally drawn full size, 1:1. Some fin and bulb drawings are drawn to be printed in two halves and joined after printing. Arrangement drawings are 1:5 and sometimes 1:4.
Make sure when printing that the “Scaling” or “Fit to Page” option is turned off in your printer setup when you print. I also have the “Print Preview” turned on as well so I can check if the page size is correct. All drawings are in either A4 or A3 size paper.
Each drawing has a 100mm scale which will allow you to see if the drawings are the correct size.
The PDF drawings are usually emailed within a few hours of receiving your order from Paypal by email. DXF and DWG formats are available for most plans. Just ask and they also will be emailed.
Printed Paper Plans are available and are printed from the same plan as the PDF. Please ask before ordering. There is usually an additional postage charge for Printed Paper Plans.
LATEST PLANS:
The Erebus -10r shape is based on the Ellipsis IOM. The design has the same LCB and waterline as the P6.1, so Phoenix 6 sail plans can be transferred over to the new hull. The hull is more rounded and has more reserve buoyancy above the waterline which will give the hull more lift over waves. The bow profile also has been lifted slightly for the same reason. Hull balance should be excellent. The deck is flat for simplicity and the plans show the same inbuilt mast ram setup I have been using successfully on both my A Class and 6 Metre designs. Any P6 sail plans used may need to be slightly altered. The Erebus sail plans are similar to the P6.1 but have been modified to suit the new deck design.
LOA 1650mm LWL 1200mm BOA 175mm 4.0kg ballast displacement 5.8kg Draught 630mm
After payment is made. I will email you the pdf file. Plan has A3, A4 sheets and a larger sheet with sections designed for laser cutting.
A printed paper plan can be supplied, postage extra.
Ellipsis M Version 2a Marblehead 2018-2024: This design is based on the successful Ellipsis IOM concept, as is the second of two sailing prototypes for the Equation M design. Of the 3 designs produced, this is favourite and was the only hull created by cutting the Ellipsis IOM in half and adding 128mm to the middle section and then re-fairing. The hull was then rescaled to the needed size and shape.
After payment is made. I will email you the pdf file.
If you require another format: DXF, or DWG, 2D or printed paper plan, postage extra.
Equation Marblehead 2019: This design is based on the successful Ellipsis IOM concept, that of correct volume distribution rather than fashionable features with the emphasis on simplicity This design is the result of two Sailing Marblehead prototypes, The Ellipsis 1c and Ellipsis 2a.
If you require another format: DXF, or DWG, 2D or printed paper plan, postage extra.
Paperclip Mk3 IOM 2024 The hard chine version of the Ellipsis and Equinox IOM’s. It is intended to be built “Tape and Glue” from 1mm plywood sheets. The PDF and DXF drawings for theses hull and deck panels are included as are the sections if you would like to build the hull over frames. The prototype built by Tony Goldsworthy seems to perform well.
The PDF Plan is on 7 A4 and 2 A3 sheets, The laser cut sheets are on 2 large sheets PDF and DXF. The Plan is also available on DXF, or DWG

Ellipsis 36 2023 is a 36 inch restricted class designs based on the Ellipsis IOM design. The 36r design was a request from a UK skipper for a lighter version of the 2017 design for both Radio and vane sailing. This design shuld be more suitable for lighter wind smooth water venues than the 2017.
LOA: 938mm LWL: 915mm BOA: 189mm Disp: 4.4kg
Goth 36 2017 is an 36 inch restricted class design based on the Goth IOM design. The original request came from John Fisher in 2013 who wanted a very light 36r for vane sailing. This design is the third design in the series, which has progressively become heavier and more successful.
New Equinox IOM Plan : The Equinox is a variant of the Ellipsis… IOM. The basic design was produced initially as a 3D printed project that never eventuated for various reasons. Two prototypes were built including a 3D printed boat which was built by John Taylor in the UK. The design incorporates several features of some of the newer IOM shapes including a fuller higher bow profile and wider stern. The design is well balanced and well behaved like the Ellipsis and should be as easy to plank from wood.
Hulls an components for this design are now available. See IOM COMPONENTS Page.
Please ask If you require another format: DXF, or DWG, 2D or 3D or printed paper plan, Postage extra.
Phoenix 4 2020 10r Every new design presents a designer with options to consider and directions to go. After a ten year gap from the P3, all 10r’s had adopted the deep keel, light weight approach and although it did seem to work I after the P5 I though that the Phoenix 4 design although fast went in the wrong direction. I always have thought about what I should have done. So this is P4- 2020, with 2020 hindsight is the result.
LOA 1550mm LWL 1250mm BOA 200mm BWL 180mm, 4.2kg ballast on 600mm Draught and P1 to P3, Marblehead style sail plans on a flat deck.

After payment is made. I will email you the pdf file. Plan has A3, A4 sheets and a larger sheet with sections deasigned for laser cutting.
Goth 36 is an 36 inch restricted class design based on the Goth IOM design. The original request came from John Fisher in 2013 who wanted a very light 36r for vane sailing. this design is the second in the series, heavier and more successful. There is also a later 2017 version which will be published soon.

Phoenix 8 – 10r: The Phoenix MK 8 is a larger more powerful boat than the last three Phoenix Mks. The P8 is a return to the simple design, No chines, no raised fore deck and Marblehead rig profiles as used from P1 to P3. This allows simpler light weight construction and fully open soft decks and shared rigs if you have a Marblehead.
LOA: 1650 mm LWL: 1240mm, BOA: 170mm, Draught: 630 – 680mm, Disp 5.7kg, SA: 1.00 m2

Epsilon RG65 – 65 2019: This design is based on the successful Ellipsis IOM concept, that of correct volume distribution rather than fashionable features with the emphasis on simplicity and efficiency.
Plans are PDF format or printed paper plan only. 3D hull and 2D bow and stern sections in DXF or DWG format are available on request.
Cerberus – 6m Something more of a challenge from a designers and builder’s point of view. A class I have always admired. This is Cerberus, my first published Six Metre design. This is the result of several requests for a design in the class and also a desire on my part build a six Metre for fun sailing locally. There are a couple of boats that will be built in the UK to join the fleet there. This design is intended to excel in moderate winds and will outperform anything of similar size drought and displacement in Australian conditions. Plans are $30 pdf plans from my PLANS page with other formats available. This design may also be available for 3D printing at a later date.
