CLASS RULE INTERPRETATIONS

June 3, 2002

CRITERIA for Rule Interpretations

1. An interpretation must be consistent with the letter and/or intent of the class rules.

2. An interpretation must not offer the potential of improved performance.

3. An interpretation that improves boat reliability without improving performance may be considered for approval.

1. Boat Battery Legal Size and Type - Ref. CR 914 NEWS Jan.-Feb.-March 2002

Interpretation of Rule 12.4

a. Boat battery cells shall have a minimum diameter of 9/16 inch (AA size) and a maximum diameter of 11/16 inch (A size).

b. Cell length shall be 2 inches maximum (AA length) and 1 11/16 inch minimum (4/5AA length) .

c. Battery packs are limited to four or five cells in a flat or square arrangement.

d. Cell chemistry is limited to non-rechargeable (such as alkaline), NiCd or NiMH.

2. Boom Fittings - Ref. CR 914 NEWS March-April 1998

The design and location of boom fittings are not controlled by the rules. Rule 9.2 reads, “All mast fittings ….”, and therefore does not apply to boom fittings.

3. Correction Weights – Rule 14.3

Correction weights shall be attached to the underside of the deck as specified in Rule 14.3.

4. Cosmetic Deck Fittings (Rule 4.6) - Ref. CR 914 NEWS May-June 2000

Cosmetic Deck Fittings (Rule 4.6) will no longer be waived at sanctioned regattas as in the past. Read the rule to ensure your boat conforms.

5. Drum Type Sail Servos – Ref. CR 914 NEWS Sept.-Oct. 2000

Only arm type sail servos are permitted in Regional and National regattas.

6. Halyards - Advisory Committee, Feb. 2002.

Halyards or other rigging controls cannot be routed internal to mast or booms.

7. Jib Sheet Routing - Ref. CR 914 NEWS May-June 1997

The jib sheet shall pass through the deck mounted jib sheet fairlead as shown on the kit drawings.

8. Keel Fillet and Non-removable Keels - Ref. CR 914 NEWS July-August 2001

Interpretation

The CR 914 is designed to have an easily removable keel. If the keel cannot be removed there can be no additional changes that result in differences from a boat with a removable keel.

1. Intersection of the keel fin with the outside bottom of the hull. There shall clearly be a gap between the fin and the sides of the keel fin recess molded into the hull bottom. This gap would be present for a removable keel. Obviously, there can be no streamline fillet at this point between the hull and keel fin.

2. Internal Structure All the original keel/hull structure required for a removable keel shall remain in place. The steel keel-rod must extend to the deck and have a nut on it as if the keel were removable. The brass tube, or pipe, that normally houses the keel rod shall be properly installed.

3. Internal Reinforcing of keel molding The keel molding on the inside of the hull may be reinforced to prevent cracks and leaks. One way to do this is described in the “CR 914 Kit Assembly Instructions” found in the kit (or the “CR 914 Upgrade Instructions” for kits purchased prior to 2002).

9. Keel Installation – Ref. CR 914 NEWS May-June 1997

The keel fin must be fully inserted into the hull until it bottoms against the hull and the keel rod nut is tight.

10. Mast Material – Advisory Committee April 2002

Only the mast and boom material supplied in the kit are legal. There was a request to permit stronger material.

11. Mast Joiner - Ref. CR 914 NEWS May-June 2000

Steel Mast Joiner is required by class rule 2.1. It cannot be replaced by another design. A magnet may be used check.

12. Mast Fittings - Ref. CR 914 NEWS March-April 1998

In Rule 9.2, “All mast fittings…” means mast fittings, not fittings on the booms.

13. Rudder Linkage – Ref. CR 914 NEWS May-June 2000

Pull-pull rudder linkage systems, using two wires to connect the servo to the rudder, is not legal. Only the Push-Pull single rod system is legal.

14. Reefing and Storm Sails – Ref. CR 914 NEWS Sept.-Oct. 2000

An owner may choose to reduce sail area as permitted by Class Rule 13. The class rules permit reducing the area of the stock sails for heavy winds. However, that smaller area shall be used for the entire regatta or series of races. Additionally, if a sail is reefed, the same limitation is in effect. The reef shall be used for the entire regatta.

15. Sail Modifications - Ref. CR 914 NEWS March-April 1998

Any alteration to the sails risks making them illegal, such as removing the luff tapes that are installed on the stock sails.

16. Sail Number Location – Ref. CR 914 NEWS May-June 1997

Location of Sail Numbers and Emblems will be liberally interpreted. The location doesn’t effect boat speed.

17. Standing Rigging - Ref. CR 914 NEWS March-April 1998

The forestay and jib halyard cannot be routed directly to the masthead. They both shall be routed upward through the hole in the forward side of the mast ring portion of the jumper strut assembly and then to the masthead.

18. Standing Rigging - Ref. CR 914 NEWS Sept.-Oct. 1998

Standing rigging must be installed as shown in the kit instructions. For example, the intermediate shrouds must run through the hole in the end of the intermediate spreader.

19. Standing Rigging- Ref. CR 914 NEWS Sept.-Oct. 2000

Shrouds (meaning the lower, middle and upper shrouds) may be connected to any of the three holes in the chain plates. (Chain plates are identified as “Eyelet plate, part 8” in the AG Assembly Instructions.)
