| EC-12 - One Design |
| More Information about this Class |
The EC-12M is one of the one-design classes comprising the AMYA-recognized fleet. Class specifications govern virtually every aspect of these yachts from hull and sail design to permitted remote controlled functions. Approximately 5 feet long, with a mast standing about six feet over the deck, the EC-12M weighs in at about twenty-three pounds.
Originally a towing tank model for a Charley Morgan twelve meter, the EC-12M can be transported in all but the smallest of cars, sailed in shallow waters, and in winds from mere zephyrs to light gales. The hull is shaped so as to shed dead leaves and other flotsam, an important feature when sailing on inland lakes and ponds. |

| IOM - One Design |
| More Information about this Class |
| The versatile International One Metre (IOM) is one of the most popular class in the radio sailing world, and many USA sailors enjoy regular travel for competition. Others prefer local sailing, and local fleets are the class backbone. USA's annual Nationals began in 1998. The class formed in the late 1980s, specifying three (3) one-design rigs with the hull/foils controlled by box rule. This format encourages evolution and created our highly refined fleet of today, where creative skippers continue to test new ideas. We race in the lightest breeze up to very strong winds and waves, where we need our smallest rig up to 35-40 knots. The hull weight limit allows amateur designers/builders to carefully create competitive IOMs and test their mettle against the best commercially available. Besides our plethora of purchase options, we have a recent global boom in home-built woody hulls now too. While the most skilled skippers usually win the regatta, no single design dominates our World Championships on even years.

| Marblehead, Marblehead - Developmental |
| More Information about this Class |
The M or Marblehead Class, sometimes called the "50/800", is a high-performance development
class designed by Roy L. Clough of Marblehead, MA in the 1930's as the largest model that
would conveniently fit in a standard American car of the time.
Due to the high performance aspect of the class, and the fact that developments in hull and rig design happen quickly, a number of sub-classes (eg. American Marblehead, Classic Marblehead, Limited Rig Marblehead) have evolved to keep older boats on the water and competitive with their peers.
The un-restriced and original iteration of the Marblehead is international, with competitive fleets worldwide.
M's are considered the largest "high tech" R/C model class with active designers/builders and
steadily growing numbers of participants. Think of them as the "Formula One" of radio-
controlled race boats.
It is a development class (unless specifically prohibited, "anything goes") with the main
restrictions being a hull length of 50 inches and a sail area of 800 square inches. The class has
matured over the years to produce a high-performance model that can be sailed in a wide range
of conditions by changing rigs.
The hull and rigs tend to use advanced materials and techniques. Boats are available from several
suppliers who can provide them from basic kit form to fully assembled. There is also an active
used boat market at the local level.
Many older designs can be made locally competitive with simple updates.
The M Class has a large ownership base, with over 3000 registered hulls in the US with that
many or more worldwide. It is sailed in most areas of the country. Competition is available from
local club to international level.
To get started, first register your boat with the Class Secretary.
Once you have registered your boat, a "measurement certificate" will be required if you want to
compete in organized regattas. To obtain this certificate, an official Class Measurer will perform
a detailed examination and measurement of the hull, appendages, sails, and rigs and if all are
found to comply with class rules, a certificate will be issued.
Registering an M Class
1. Become an AMYA member and obtain your AMYA membership number. No registration
number will be issued without an AMYA membership number.
2. Complete the AMYA Yacht Registration form contained in Model Yachting. Include your e-
mail address on the form. Make out a check for $10 to Bruce Andersen and mail it with the
Yacht Registration form to him. Do not make out the check to AMYA - registration funds are
used for Marblehead Class expenses and are not part of the AMYA.
3. If you are transferring ownership include the existing registration number and previous
owner's name.
4. You will be issued a new sail number if this is a new registration, or a card with the old sail
number in your name if this is a transfer of ownership of a previously registered boat. A new
number may be issued if the provenance of the hull is unknown. |

| Star 45, Star 45 - One Design |
| More Information about this Class |
| The Star 45 has a 45" long hard-chine hull; it is a semi-scale model of the full-size International Star. Weighing from 12 to 13 pounds, carrying about 1000 square inches of sail area and with a ballast to weight ratio approaching 70%, Star 45s are fast and responsive. When properly trimmed, the boat will sail hands off to windward. A Star 45 is fun to build, and like the full-sized Star boat, it was designed to race. It has a rubber bumper on the bow to avoid damaging other boats.
A Star 45 can be homebuilt from wood or fiberglass with plans available from the American Model Yachting Association. Laser-cut frames based on those plans can be purchased, or major hull components in fiberglass can be obtained from Class suppliers. One can also commission a new Star 45 from a professional builder to any stage of completion. The Star 45 is a one-design class, but some tolerance is allowed with the underwater appendages, rig construction and sails.
You can register or transfer a boat online via the link on this page, or if you prefer the paper form, you can find either method on the Star 45 Class website at star45class.com |
