The Class Rules

The International Contender Class Rules are regularly reviewed in order to prohibit the
use of exotic materials or expensive equipment. This prevents the escalating cost of sailing
"the Ultimate Singlehander".

In recent year the costs of spars from aluminium have been rising while availability
is decreasing, the cost of carbon fibre spars has been decreasing, therefore the class
has approved the use of carbon fibre masts and booms. Loose footed sails are now permitted.

Class members have repeatedly refused to reduce the bare hull weight because members
wish to preserve the market value of older hulls. Change the rig, protect the hull

The rules permit licensed and amateur builders to construct this boat. Hulls are
built successfully in all wood, composite glassfibre hull/ wood deck and all glassfibre.

The International Contender has proven to be suitable for a wide variety of sailors,
both male and female. The weight of successful sailors range from 55kg to 95kg (120lbs to 210lbs) and
heights from 165cm to 200cm (5ft 4 to 6ft 4). Contender champions' ages vary from 20 to 50 years.
The developments of the boat have enabled the boat to be raced even in rough open
sea conditions.
