Class Rules for the North American Mystere 4.3 Class Association:
Spring 2002
2002 North American Mystere 4.3 Class Rules -Final Draft
- Objective
- Define configuration of Mystere 4.3 catamaran for one-design racing in North America.
- Define baseline configuration of Mystere 4.3 catamaran for Portsmouth Handicap racing in North America.
- Intent
- Promote Fair and Fun racing.
- Maintain the boat’s safety features.
- Keep boat performance equal.
- Have the boat appeal to a wide audience.
- Preserve and enhance the boat’s rigging and sailing simplicity.
- Allow customization to accommodate varying sailing styles and crews.
- Allow design evolution from the manufacturer to ensure commercial viability.
- Minimize cost of maintaining a competitive boat by preventing a technology race and permitting purchase of components from competing suppliers.
- Encourage the use of racing tactics and sailing skills.
- One-Design Class Racing
- The design and development of the Mystere 4.3 is directed toward a one-design class where the race is between sailors and sailing skill, not boats. Any alterations to the hull form, construction, equipment or spars as supplied by the builder except as is specifically authorized by these rules, are a breach of these rules and are prohibited.
- Spirit/Rationale
- The intent and objectives of these rules are sometimes contradictory. Permitting changes that allow the boat to appeal to a broad audience reduces the boats equality. For example, adding an additional cleat to hold the spinnaker sheet helps a singlehanded crew manage the boat, but that advantage translates into better performance than other boats and more cost.
- The challenge is to balance these various goals as best we can. So, the spirit of these rules can be summarized by:: If it doesn’t do anything but make the boat faster, NO. If it makes cheaper and safer and easier, YES
- In particular, these guidelines lay the foundation:
- Overall dimensions standardized.
- Changes to the underwater form Disallowed.
- Sail size (but not much else about them) standardized.
- Convenience Items Allowed.
- Changes to the existing controls Allowed.
- Addition of new controls Disallowed.
- Definitions
- The North American Mystere 4.3 Class Association shall hereafter be referred to as NAM4.3CA.
- Mystere International and any of their licensees that are in good standing with respected licensors shall hereafter be referred to as Mystere.
- International Sailing Federation shall be referred to as the ISAF.
- The International Sailing Federation Racing Rules shall be referred to as the RRS.
- Eligibility
- The NAM4.3CA has the right to declare ineligible any Mystere 4.3 which does not conform to the spirit, objective and intent, as well as the letter of these rules and official drawing and specifications held by the NAM4.3CA. In the event the drawings are not held by the NAM4.3CA, they shall be held by Mystere
- Deviations
- If you are in doubt, check with the NAM4.3CA first. Approval must be in writing by the Rules Chairman or his designee.
- Design Features and Changes
- Only Mystere 4.3s manufactured by Mystere are legal for class racing. Nothing may be changed or removed from any Mystere 4.3 that will in any way alter the structural integrity, design function, or built- in safety features of the boat. Changes that fall under the category of safety and strength shall have prior written approval. Approved changes are as follows: Stronger gudgeons, larger diameter wires , slight shimming of crossbars, and reinforcing not affecting water flow. Except as allowed in these rules, any changes or additions that in any way can be construed as speed devices are not class legal.
- Safety Equipment

The intent of this rule is to accommodate schedule conflicts of crew members, sharing of the fun, and children’s short attention spans and limited strength, while preventing picking the best crew for the weather of the moment.
- There is no class minimum or maximum crew weight.
