Interpretations of the Rules Committee will automatically become integrated into the Class Rules at the Annual Meeting, unless overruled by a majority of the owners present at the meeting.

 

PART 2: RULES AND SPECIFICATIONS

 

1. INTERPRETATION: Specifications, however complete, cannot anticipate every possible situation that may arise. If a point is not covered herein, a ruling should be obtained from the Rules Committee. In interpreting these rules and specifications, the Committee shall consider the intent rather than any technical construction that might be derived from the wording and shall bear in mind at all times the basic principle of the specifications, which is to maintain the S2 7.9 Meter Class as a one design class.

"Nothing is optional in these rules and specifications unless so stated."

In the absence of the specific rules to the contrary, the rules of the United States Sailing Association (U.S.S.A.) shall apply.(As an example, the spinnaker pole is to be attached at the single fixed ring on the mast, use of a second ring or sliding track is not an allowed option.)

 2. STANDARDS: The original plans and specifications on file with S2 Yachts Incorporated, or a certified copy of these plans acquired by the Association, shall be considered as setting forth the official standards with respect to hull, spars, and rigging.

 

3. ELIGIBILITY OF BOATS: It shall be the responsibility of the individual fleets to ensure that their

member boats abide by the Association rules and specifications for local competition. The Rules Committee will rule on any matter submitted to it by a local fleet. The measurement and certification of S2 7.9 meter boats to be sailed in the International or Regional Class Championships shall be performed by the sponsoring club or it's appointees, under the guidance and control of the class Governing committee.

An S2 7.9 Meter may be challenged by means of a protest in writing stating the grounds thereof, submitted to the president, who shall refer it to the Rules Committee for a decision. Any such protest shall be accompanied by a check for $25, which shall be returned if the protest is sustained and otherwise paid into the Association treasury. The Rules Committee and the Governing Committee jointly shall have the responsibility to declare a boat ineligible if necessary. This gives the committees the authority, without a formal protest, to declare a boat ineligible for a class-sanctioned event.

7. SAILING WEIGHT: The sailing weight of the 7.9 meter shall be as follows:

 7.1. Weight - Class Sanctioned Regatta's have a minimum weight requirement of 4400 pounds for the Inboard version and 4600 pounds for the Outboard version. (i.e. if a boat is light, add the weight required to meet the minimum). The Regatta Committee may require each boat to be weighed at the regatta (must provide time and means). When weighing the Boats, the only equipment allowed on board that is not permanently affixed and allowed under the class rules shall be:

  7.1.1. factory cushions

7.1.2. one battery

7.1.3. standard blocks

7.1.4. hatch covers

7.1.5. mast

7.1.6. boom with main sheet with sheet tackle

7.1.7. rudder

7.1.8. standing rigging

7.1.9. outboard motor

7.1.10. required safety equipment

 7.2. No fuel, water, waste or anything else shall be aboard when weighing. Ballast is to be added to bring the boat to the correct minimum weight. Such ballast shall be non-functional materials and located in the engine compartment. The scale used for weighing must be certified accurate within +/- 25 Ibs. The weighing process shall be done under the auspices of the Class Association. Each fleet shall appoint a fleet measurer to supervise and document each certificate. Copies of the certificates shall be sent to the National Class Association. The certificates must contain the scale type and serial number, date and place of weighing, list of all movable items on board while weighing, and the weight of each item. Also, list all permanently attached items not standard such as the factory cabinet over sink or the stereo. Removal of any of these items will invalidate the certificate. These certificates must be signed by the fleet measurer, president and owner of the boat and sent to the class association. Any inboard yacht which has removed the prop, prop shaft, strut or engine will be considered an outboard, and will be required to meet the weight requirements for an outboard yacht.

7.3. Any boat weighed which exceeds the minimum required weight may remove the two center cushions for the purposes of reducing the total weight, provided their removal does not bring the yacht's overall weight below the class minimum. Bow and stem cushions shall not be removed at any time.

7.4. Alternate Procedure - For non sanctioned events or when authorized by the Governing Committee: For boats that have been previously weighed at an International Championship the average weight from all Internationals sailed will be used as the weight of the boat. Sufficient weight will then be added to bring it up to class minimum. These weights are to be obtained from the Rules Committee, which will keep all weights on file for reference. Outboard models, which have not been previously weighed, will carry 200 Ibs. of additional ballast to equalize it's performance with the inboard model. The weight of the outboard engine itself (not fuel tank or fuel) may be applied to this requirement. The remainder should consist of sand bags, a metal block, or some other material that has a fixed weight. This ballast should be placed in the storage compartment that would normally house the inboard engine. Any inboard yacht which has removed the prop, prop shaft, strut or engine shall be considered an outboard, and will be required to carry the 200 Ibs of additional ballast. Outboard yachts may (not shall) carry their outboard on the transom while racing. (The weight of the outboard would still count toward the 200 Ibs.)

8. CREWS: The number of persons required or permitted to be carried as crew shall be decided by the local fleets, and in the absence of any local rules shall total four of five including the skipper. In Regional or North American Championship races, the crew will total four or five including the skipper. All crew, except the Helmsman, must position their torsos inside the lifeline(s) in accordance with U.S.S.A. Rule 49.2. (i.e. no "butt hiking" is allowed)

9. REQUIRED ITEMS: Required items will include:

  9.1. operable fire extinguisher

9.2. manual bilge pump

9.3. anchor (minimum 8-s)

9.4. anchor line (minimum 3J8' x 150' length)

9.5. life jackets for each of the crew

9.6. horseshoe buoy (or man overboard module

9.7. one compass

9.8. fog horn, running lights

9.9. battery

9.10. an operable engine (minimum 4.5 hp.)

9.11. a flare kit.

10. DROP KEEL: The drop keel may be retracted partially or fully while racing. Small improvements in speed may be achieved.

11. GENERAL SAIL REQUIREMENTS: In an effort to clarify and monitor sailcloth requirements, effective Nov. 1, 1986, the following procedure will be implemented

11.1. All class sails shall be stamped, dated and signed by the Sail makers as to the type and weight of the material used. (i.e. Dimension 2600, Nov. 3,1986, XYZ Sails)

11.2. All class sails must be made from woven (base) polyester or nylon materials (see Appendix I for recommended materials).

 11.3. Composite sail construction (i.e. lighter weight cloth in low stress areas) is allowed. Composite sails will be allowed if all materials used are equal to or greater than the minimum weight cloth specified. If you have a question as to a technique or process, please ask the Rules Committee for a review.

 11.4. Approval of materials and composite construction is the responsibility of the Rules and Specification Committee. Sail makers are encouraged to submit samples, sketches, with comments for approval. Once approved, they will be added to the approved list, which will be available on request.

 11.5. Beginning January 1994, all competitors will be allowed to replace only two of the following three sails per year: Mainsail, Class Genoa (155%), or class spinnaker. (Not to include the storm jib or working jib). For this requirement, year is defined from the last day of the International Championship to the last day of the following year s international Championship.

 12. SAIL DEFINITIONS AND MEASUREMENTS

12.1. Head. The head shall be taken as the straight line intersection of the luff and the leech ignoring any round or hollow of either, except for the main which shall be taken as the highest point of the sail projected perpendicular to the luff or its extension. A jib luff tape will be extended for this purpose.

12.2. Clew: The clew shall be taken as the straight line intersection of the leech and foot ignoring any round or hollow of either.

12.3 Tack: The tack shall be taken as the straight line intersection of the luff and the foot ignoring any round or hollow of either. A jib luff tape will be extended for this purpose.

12.4. Jib and Genoa: To be rated as a jib or genoa, at any distance from the head, the ratio of girth to foot length shall be no greater than the girth’s proportionate distance from the head, i.e., midgirlh no greater than 50% of foot length, upper quarter girth at 25% from the head no greater than 25% of foot length, etc.

 

12.5. Spinnaker: The spinnaker shall be symmetrical about its centerline in both shape and construction. Luff and leech shall be of equal length. The mid-girth shall not be less than 75% of the foot length

12.6. P - Mainsail Hoist: P = 29.5’. Shall be the vertical dimension measured along the aft side of the mast, from the horizontal plane depicted by the top of the boom to the lower edge of the upper band.

 

12.7. E - Boom Length: E = 12.25.’ Shall be the horizontal dimension taken from the aft side of the mast to the forward point of the band at the aft end of the boom.

 

12.8. When any band is not present, the dimension shall be taken to the maximum point to which the sail may be extended. When banded, mechanical stops (pins, chocks, bolts, etc.) shall be permanently installed to insure that the sail cannot be stretched outside the limits defined by the bands. Most S2 7.9’s have a 1/4 x 20 tapped hole at the boom band. To meet the 12.25’ "E" dimension, a screw and ¾" OD washer is normally needed as a stopper.

 

12.9. Mainsail Girth: The cross measurement shall be the distance from the leech measurement points to the perpendicular (nearest) point on the luff (outside edge of the sail and/or luff rope). The points on the leech from which the cross measurement is taken shall be determined by folding the aft upper comer of the headboard to the clew intersection and make a mark at the fold in the center of the leech. Then fold the headboard to the mark in the center and make a mark at the fold in the upper quarter of the leech. Then unfold the sail and measure between the two marks and the luff.

 

12.10. Jib/Genoa Girth: The cross measurement shall be the distance from the leech and luff measurement points. The points at which the cross width measurements are taken shall be determined by folding the head (as projected) to the clew and the tack intersections and making a mark at the fold in the center of the leech and luff (mid-girth). Repeat, folding the head to the midgirth measuring points and make a mark at the fold at the upper quarter of the leech and luff (upper quartergirth). Then untold the sail and measure between the corresponding marks.

 12.11. Foretriangle Height: I = 30.5’. I is from the base of the foretriangle to the apex. It is not easily measured on the 7.9. The manufacture of the mast and boat actually determine this dimension.

 12.12. Foretriangle Base: J = 9.5’. The horizontal dimension between the vertical plane described by the forward most point on the forward side of the mast to the vertical plane described by the intersection of the centerline of the forestay (or extension), and deck (or extension).

 12.12. LP: Shall be the dimension measured on the perpendicular from the luff (outside edge of the sail and/or luff rope) to the clew.

 12.13. Measurement of Jibs/Genoas: Shall be measured with such tension as will remove all wrinkles across the body of the sail between points of measurement. If, when the sail is laid flat, the leech is entirely inside a straight line from the head to the clew, it will be considered to meet girth requirements. If it does not, girth stations, as above, shall be measured.

 12.14. SMW - Maximum Girth: shall be the spinnaker maximum width, whether at the foot or across the body of the sail between points of the luff and leech, equidistant from the head.

 12.15. SL - Maximum Luff: shall be the greatest length of spinnaker luff or leech measured along the edge of the sail from the head to the clew. Measurement of the Spinnaker shall be measured with such tension as will remove all wrinkles across the line of measurement. When measuring the luff and leech, approximately 7 pounds of tension should be used

 12.16. Spinnaker pole: To be measured with pole perpendicular to the mast and at right angles to the fore-aft centerline of the boat: shall be <= 9.5’ from center of the mast ring to the outboard end of the pole.

PART 3B – S2 7.9 METER CLASS ASSOCIATION REGIONAL CHAMPIONSHIP AND CLASS SANCTIONED EVENT RULES Adopted by general membership vote 7/97

 

These rules and regulations are to be used for Class sanctioned regional, NOOD, any one-design regatta that is promoted as a "championship" or similar (other than fleet championships), or where participants from more than one fleet are invited or permitted entry. Variances must be approved in advance by a majority of the Class officers (governing board). Event organizers and fleets are encouraged to use these rules as applicable for all such events.

 

1. GENERAL

All S2 7.9 National Class rules, requirements and specifications regulations, (including sailing weight and sail limitations) are in effect, except as modified below. Boat inspections and sail measurements may or may not be carried out; however, any boat may be challenged by protest per the provisions of the Class rules. In any case, the honor system is relied upon for compliance with the letter and spirit of the Class one-design rules.

 

2. WEIGHT

Boats may or may not be weighed. If boats are not weighed, any that have had a previous "official" weight recorded at a previous International Championship regatta may use their most recent official weighing, and are expected to use the corresponding ballast, if necessary, to comply with the class minimum weight.

Boats that have not been officially weighed, or have been modified since weighing, will either use the Class specified additional ballast or, if provided, can arrange for an unofficial weighing to be used for the particular event or series. Expense of such a weighing will be born by the requesting member. A local fleet captain, representative, or event organizer must be present at the weighing. A complete weight checklist (see appendix) should be kept in the local fleet file, and a copy forwarded to the Class rules chairman. Availability of an unofficial weighing is not guaranteed.

 

3. SAILS

Spare sails may be carried, but may not be used except to replace a sail damaged beyond repair (i.e. cannot be temporarily repaired using sail repair tape or hand sewing) while racing. A replacement sail may not be a new sail (built since January 1st of the same year, or the most recent International Championship regatta, whichever was earlier. Race results will not be "official" until the damaged and replacement sails have been examined by a member of the governing board, rules committee, local fleet representative and/or the event organizers.

 

4. CREW

The boat will be sailed with no more than five, nor less than four crew, including the skipper. (Exceptions would be club races, JAM classes, single and doublehanded races, etc.). Boats may have a different number of crew on different days. Crew substitutions are allowed.

 

5. CLASS MEMBERSHIP

The owner(s), (if on board for any race), and the person whose name is on the regatta entry form (if different from the owner(s)) must be a current regular or associate member in good standing of the S2 7.9 Class Association prior to the scheduled start of the first race of any regatta or series.

Furthermore, for every race, at least one member of the crew must be a current regular or associate member in good standing of the S2 7.9 Class Association.

Membership in good standing requires that a properly completed membership application and dues ($15.00 US) have been received by the S2 7.9 Class treasurer. It is the regatta entrant’s responsibility to confirm his/her membership status.

Boats not meeting this requirement are subject to protest and will not be scored in any race in which the requirements are not met.
