Executive Committee
The IRSA Executive Committee was elected by the General Assembly, May 2016 under the terms of Articles 7.
IRSA A Class
Boats in IRSA A Class are not limited in length, but are controlled by a formula which balances waterline length, displacement, and sail area. Using this formula, sail area reduces as displacement reduces and as waterline length increases. The formula was devised in 1922 by Major Malden Heckstall-Smith, then editor of the Yachting Monthly, for testing an alternative to the International Linear rule. A similar rating rule is still in use today in the 5.5 Metre class rule which also uses elements of the Linear rule. Although A Class boats are of a heavy ‘type’ there is flexibility to create lighter hull forms which excel in brisker conditions. 
Nevertheless they are big boats compared with other rc classes and a fleet of A Class boats is an impressive sight. A modern A Class will usually be made using carbon fibre – hull, foils and spars.
The class was given Classic Class status in 2004. For full information concerning what this means please see the IRSA Regulations.

IRSA Ten Rater Class
Boats in the IRSA Ten Rater (10R) class are not limited in length by the class rules and usually have overhangs extending beyond their waterline endings. They are generally light, narrow, stable, seaworthy and fast. This IRSA international rule is based on the 1887 “length and sail area rating rule” which allows shorter waterline length boats to have higher sail areas, while longer LWL boats have smaller sails. It is an ‘open’ rule with great freedom to develop design and construction, particularly in rigs and sail plans. Many different hull forms can be found in the 10R class. 
A modern 10R will usually be made almost entirely of carbon fibre – hull, foils, spars and fittings.
The Ten Rater class is managed by its own International Class Association, the ITCA. Please visit the class website at www.tenrater.org

International One Metre Class
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
