Class Rules

Ammended  3/24/2011      


Section 1: Scope
These rules will apply to all competition in which the RAIDER sailboats are used as a "one-design" class sailboat in club, US Sailing or other sanctioning bodies in North America. These rules will only pertain to the design, equipment attached to and carried on or used by the skippers and crews of the subject boats. They will not govern the operation of the vessel nor the rules that are used by the organizing body in the competition itself.

Builders and/or owners shall not attempt to violate the spirit or the letter of the rules by modifying existing yachts or producing new yachts with the intention that they be basically faster. The use of any design variation not specified in these rules which could have an effect on the speed or performance of the RAIDER is prohibited.

Builders and owners shall consult with the RAIDER Class Association for a written ruling before attempting new forms of construction, modification and/or repair, which might affect the RAIDER's basic speed or performance.

Improvements. As a class grows, improvements in boat speed and boat handling are discovered. It is the responsibility of the class association and its directors to recommend and approve changes that will affect boat speed or performance. Changes in hull form that will obsolete previously manufactured boats will NOT be allowed
At this time, the hull form of the Raider II (all Models) shall  for competition purposes be considered equal to the standard Raider (Raider Sport and Raider 16) providing the rig and sailplan of each is equal or equivalent. Ie: the Raider Sport w/o spinnaker may compete equally with the Raider II. The Raider II Sport and the Raider II Turbo will compete in separate classifications. The Raider II Sport and the Turbo model may compete equally against each other  if the Raider II Turbo does not carry a spinakker. A Raider Sport that has been upgraded to Raider II Sport  rig and rigging specifications will compete equally. A Raider Sport that has been upgraded to Raider II Turbo  Rig and Rigging specifications will compete equally.

The Class Association may sanction races in both a novice (blue) and racing (gold) division. The following restrictions shall apply, except as noted, to all boats participating in races sanctioned by the Class Association, as provided in the by-laws.

Both spinnaker and non spinnaker boats may race in the same regattas as specified by the race organizers. It is up to the race organizers to determine as to the use of spinnakers prior to the regatta start. Any boats carrying spinnakers at the beginning of a regatta  or series will be considered as spinnaker boats. Classes may be split as to spin / non-spin.

Class sanctioned Regattas
The individual identified as Skipper on the entry form shall be a Full Member in good standing of the RAIDER Sailboat Association and shall be on board for all Class sanctioned regattas unless a substitution is authorized in writing by the Race Committee.

Any member of the crew may take the helm at any stage of the race or event.

A helmsman who has raced in the blue division may change divisions during a particular season and participate in races held for the gold racing division. However, a helmsman in the gold division may not in the same season helm in the blue racing division. The intent of this rule is not to restrict a helmsman's opportunity to race, but rather to prevent an experienced helmsperson from dominating an event designed primarily to introduce less experienced sailors to the enjoyable aspects of sailing competition.
