CAL 20 ASSOCIATION BYLAWS
ARTICLE I - ELIGIBILITY
1. A Cal 20 is eligible to compete in one-design competition only if it has a valid Class measurement cenificate, has been properly registered, and is owned by a qualified member in good standing of the Association.
2. Skippers in one-design Class races shall be Active members of the Association. The skipper must be the helmsmen, in Class Championship qualifying regattas.
3. All members of the crew must be Corinthians.
ARTICLE II - SANCTIONED EVENTS
1. Any series for a Cal 20 Championship territorially greater than one fleet, or events for perpetual or semi perpetual trophies, must be sanctioned by the fleet in whose water the event is held.
2. The Executive Committee may "outlaw" any event for cause.
ARTICLE III - CLASS CHAMPIONSHIP
1. The Cal 20 Class Championship shall be held annually to determine the champion of the Cal 20 Class. The Cal 20 Class Champion Perpetual Trophy shall be held by the winning fleet or unattached member until the next Class Championship series, subject to the approval of the Executive Committee.
2. The Class Championship regatta is an open event until such time as the Governing Board deems it necessary to make it a restricted event. The method of determining qualifications for the right to enter the regatta shall be set by the Goveming Board.
A. The allocation for each fleet will be based on the number of Cal 20s owned by active members in the fleet. The Governing Board shall announce the allocations, if any, on or before May 1 of each year.
B. To qualify, an Active member must sail in a minimum of three Cal 20 Class events between the previous Class Championship and the Championship in question. A Cal 20 Class event is defined as a weekend regatta or an individual series held over a period of time where a minimum of three races (in that regatta or series) are completed by the skipper/helmsman. Any Cal 20 that qualifies for entry in the Championship must be sailed by the skipper who qualified in that boat. With prior approval from the Class Championship Committee, a skipper who has qualified may sail a Cal 20 other than the boat in which he or she qualified.
3. Each Cal 20 must be certified as eligible by the Measurement Committee and the Secretary of the Association prior to the first race. The Race Committee or the Measurement Committee may require a re measurement of the hull, spars or sails at any time prior to the trophy presentation.
4. Subject to the approval by the Executive Committee, the fleet or unattached member having won the event the previous year shall have the privilege of selecting the site for the Class Championship, except that:
A. The Class Championship cannot be hosted by the same fleet in two consecutive years.
B. It must be held on open water as free as possible from headlands, shoals and obstructions to navigation.
C. It must be held outside of Southern California at least once every 5 years.
5. The responsibility for arranging for and providing proper facilities, entertainment, prizes, etc. shall rest with the fleet on whose waters the series is held. In this regard the host fleet shall be guided by the Governing Board for the Class Championship Committee.
6. To qualify as a Class Championship, the series must have at least three completed races. If more than five races are completed, there shall be one "throw out."
7. Total crew for each boat in Class Championship competition is limited to a maximum of four persons and a minimum of two. Children under twelve years old are not counted as crew.
8. No Cal 20 shall be prevented from entering a re-sail of any uncompleted race for any cause arising out of an incomplete race.
9. Ties will be broken in favor of the yacht that defeated the other yacht or yachts involved the most number of times.
10. The act of deliberately and willfully sacrificing one's place in a race, thereby substantially injuring or improving the chances or place of others, is forbidden and shall be grounds for disqualification. "Covering" or "luffing," shall not be deemed team racing tactics, provided the yacht is sailed within the Racing Rules of Sailing (RRS) and in a manner consistent with maintaining or bettering its own standing in the race. In flagrant cases affecting the point scores among the leaders, the Class Championship Committee shall have the power, with or without a protest, to order the race re sailed, bar the offender from the re-sailed and remaining races, and recommend his or her suspension to the Governing Board.
11. HONOR AWARDS may be displayed on the mainsail. The award insignia shall consist of colored chevrons and the last two numbers of the year in which the award was won. The chevrons shall be vertically stacked, apex upward, not more than three inches apart. The numerals shall not be more than three inches high.
A. The number of chevrons shall be as follows:
• Three chevrons for the first place yacht.
• Two chevrons for second place.
• One chevron for third place.
B. The following chevron colors shall denote the honor awards: Class Championship - Gold District Championship - Red Fleet Championship - Black
C. Awards rank in the following order:
• Gold
• Red
• Black
One gold chevron outranks three red chevrons.
It is suggested that the skipper display only one set of chevrons representing his highest honor award. Only one set of chevrons representing a particular honor award may be displayed on the sail at a time. If the skipper has won the same award twice or more, he or she may display numerals for each year.
D. Honor awards are presented to the skipper, not to the boat. They shall be retained by the skipper for use on any Cal 20 that he or she may sail while a member of the association.
ARTICLE IV - SPECIFICATIONS
1. The official number allocated to each Cal 20, shall be permanently molded or stenciled in legible numbers in a visible place on an interior surface of the hull.
2. HULL: Construction of all hulls shall be of molded fiberglass in or over an approved mold manufactured by Jensen-Wenke or its successors. Hull shape or hull stiffening modifications are not allowed except as necessary for repairs. In those cases, proof of return to a pre-repair condition shall be certified and approved by the local fleet measurer.
A. Because of the assumed impact on boat speed, any strengthening or stiffening below the waterline shall be disallowed except where absolutely necessary to preserve integrity. Limited strengthening above the waterline which does not affect boat speed (such as mast support members or hatchway corners) may be approved by the local measurer if it's deemed necessary to preserve the integrity of the boat.
B. A single fore and aft stringer may be installed on each side of the bow to reducing bow deflection (oil canning). The stringers must be located inside the hull, horizontally, halfway between the forepeak berth and the deck. The stringer must terminate before the mast step deck beam or the bulkhead. It may be wood, foam or PVC material and must be bonded to the hull. The maximum profile dimension of the stringer cannot exceed two inches.
C. A single cockpit support connecting the cockpit floor to the cabin sole pan may be installed to prevent cockpit corner cracking.
D. The use of carbon fiber and similar "hi-tech" materials to provide equal or increased stiffness with a decrease in weight is strictly prohibited.
E. Strengthening the upper andJor lower gudgeon fastenings with a backing plate, or a backing block mounted on the interior side of the transom, shall not be construed as a stiffening modification, and need not be approved by the local Fleet Measurer.
. MOTOR WELL: Cockpit drainage through the motor ~vell, is required for all boats. Taping-over, glassing-in or sealing the motor well in any form is prohibited. The motor well must be self draining and the well plug removable from the cockpit. The thickness of the plug is limited to 3 inches. Any attempt to fill the well with foam is illegal. Boats not equipped with a motor well by the builder shall carry 20 pounds of ballast weight in the location of the missing motor well. Adequate cockpit drainage is required.
4. The RUDDER profile shape must be maintained as delivered from the boat's builder. Rudders must weigh at least 25 pounds with gudgeons, and have a maximum thickness of no more than 2.25 inches.
. KEEL:
A. The leading and trailing edges of the mounting flange may be faired into the hull. A .25 inch fillet is allowed between the sides of the flange and the hull.
B. The vertical fin may not be altered from the original factory profile. It may be faired, but the maximum thickness shall not exceed 1.5 inches. Maximum profile cord lengths:
• 6 inches down from flange - 49.75 inches
• 12 inches down from flange - 47.75 inches
• 18 inches down from flange - 45.625 inches
C. The bulb may be faired but not altered in shape.
6. When original materials, replacement parts or their equivalents are not available for timely refurbishment or repair, a member may petition the Chief Measurer for permission to use substitute parts or materials.
7. The cockpit lazarette hatch must be hinged and functional.
8. HATCHES: All hatches must be carried on board while racing. The main hatch slider and crib board must be constructed of wood, fiberglass or plastic. The main hatch slider must be carried in place and there may not be any fastened obstruction that limits the horizontal opening to less than sixteen inches.
ARTICLE V - INTERPRETATATION OF SPECIFICATIONS
1. Specifications, however complete, cannot anticipate every situation that may arise. If a point is not covered, or governed by the dictates of common sense, a ruling must be obtained from the Measurement Committee. In interpreting any point not covered, or words of obscure meaning, the Measurement Committee will consider the intended meaning rather than any technical misconstruction which may be derived from the wording. Rulings shall be based on the principle to maintain the Cal 20 as designed by C. William Lapworth, built by Jensen Marine or its successors, and configured as allowed by the Association Bylaws.
2. Questions regarding the interpretation of Bylaws restrictions, specifications, or the legality of anything about the boat, rigging, sails or equipment, shall be referred to the Chief Measurer. The Measurement Committee shall make a prompt decision which shall be published in the following issue of the Association newsletter. Rulings or decisions too late for such publication prior to a Class Championship regatta, shall apply only if published in the Notice of Race at least ten days prior to the event.
3. All rulings and decisions made by the Measurement Committee during the current season are subject to ratification by a two-thirds majority of the votes at the annual meeting of the season in which the rulings were made. If ratified, these rulings shall be added to the Bylaws. If rejected, such rulings are null and void effective immediately after the Class Championship series of that year. A report of the rulings that were ratified or rejected shall be published in the newsletter.
ARTICLE VI - REPAIRS
Major repairs above or below the waterline should not exceed the original strength or stiffness of the boat. Such repairs are to be made with similar materials when possible, i.e. resin for resin, wood for wood of similar density, weight, strength and stiffness. Polyester resin may be substituted for epoxy resin. Major repairs shall restore up to the original stiffness of the boat without lightening the boat from its pre-repair condition.
ARTICLE VII MEASUREMENTS AND CERTIFICATES
1. A Cal 20 must have a valid measurement certificate that is no more than two years old to compete any sanctioned one-design event.
2. When a boat is weighed and issued a certificate at an annual Class Championship, that certificate supersedes any previous certificate.
3. Fleet Measurers shall be elected by their respective fleets and shall derive their authority from the Chief Measurer. Measurers shall not measure their own boats.
4. A new measurement certificate may be required if alterations or repairs affect more than half of the hull, or are extensive enough to warrant a re-measurement in the opinion of the Measurement Committee.
5. WAIVERS: A boat which does not measure within stated specifications due to factory tolerances may petition for a waiver. Only "as-built" variations that are not correctable in a reasonable and practical manner are eligible. The measurer may use any means to verify the need for a waiver, including disassembly or drilling, with any cost borne by the petitioner. Such waivers shall relieve only the subject tolerance and shall not permit broader modification. Waivers shall be requested by the appropriate Fleet Measurer, approved by a majority of Fleet Captains, and issued by the Association Measurer. Waivers may be subject to yearly review when so requested by any three Fleet Captains.
6. Reasonable grounds must be shown before a Cal 20 with a valid measurement certificate can be subject to a measurement or a protest of measurements. Each measurement protest of a certified Cal 20 must include a $15.00 filing fee, which is returnable if the protest is sustained. A Cal 20 is always subject to re-measurement by order of the Governing Board, Measurement Committee, or the Class Championship Committee, in which case the filing fee does not apply.
ARTICLE VIII MINIMUM WEIGHT AND BALLAST
1. All boats shall weigh a minimum of 2040 pounds with only the required equipment on board. For the purposes of this article, a Cal 20 consists of a hull and deck, cast iron keel, standing rigging, running rigging, rudder, tiller and spars.
2. The minimum weight must also include:
A. Safety equipment listed in Article XIV 1.
B. Main hatch slider and crib boards.
C. Berth drop boards (3/8" plywood).
D. Head or head ballast. (If a working ceramic head with through hull fittings is absent, 31 pounds of head ballast must be carried in a fixed position 18" forward of the mast step beam. A portable head, filled with liquid, weighing at least 31 pounds, placed in the original head position is acceptable.)
3. BALLAST: Any boat weighing less than 2040 pounds in measurement trim shall add ballast to bring the boat up to the minimum weight. Up to the first 65 pounds of that ballast may be carried anywhere in the boat, and all or part of that total may be comprised of an engine and if additional weight is required, half of it placed a minimum of 18 inches forward of the mast support beam, with the remainder positioned 72 inches aftof the mast support beam. Ballast is defined as material serving no useful purpose aboard a Cal 20 other than dead weight. However, a battery, not including cable ties or supports, may also be used. Required ballast weight, if any, shall be listed on each measurement certificate. Ballast shall not be moved while racing, and its removal shall void the certificate.
ARTICLE IX - SPARS
The mast and boom shall both be made of one piece IOI1OW extruded marine grade aluminum as designed by C. William Lapworth. The wall thickness must be uniform for the full length of the extrusion. Redistributing or reducing weight is not allowed.
Only boats that came from the builder with a tapered mast as original equipment are allowed to have a tapered mast (hull numbers 1-124). If the original mast is replaced for any reason, it shall be replaced with a non tapered mast in accordance with class rules.
l. The minimum oval mast shape is 2.5 inches by 3.875 inches. Approved mast sections are:

ARTICLE X- STANDING RIGGING
1. Standing rigging shall be essentially as shown on the plans. No changes to the standing rigging are permitted except:
A. An adjustable backstay is allowed.
B. Forward lower shrouds are optional.
C. Turnbuckles may be added above the spreaders to adjust the jumper shrouds.
2. Standing rigging shall be braided stainless steel wire. Minimum shroud and headstay wire size is 1/8 of an inch (3 millimeters). The minimum size for backstay and jumper wires is 3/32 of an inch (2.5 millimeters).
3. The spreaders shall not be less than 30 inches long, measured from the mast to the inner edge of the shroud.
4. The headstay may be attached to a "bow tang" or steel strap, through-bolted to the bow, rather than to the stock plate on the foredeck, if the "J" measurement is not greater nor less than 7 feet, 4 inches (+1 inch or -0.5 inch). If the Cal 20 does not have a bow tang, the "J" measurement shall be as delivered from the builder.
6. The load of the aft lower shrouds may be transferred to the main hull through the standard deck fitting and through-deck fittings to an interior chainplate via a turnbuckle, cable and/or tang.
7. The backstay must be attached to the transom and may be split, up to a distance of ten feet above the deck, to permit a symmetrical arrangement.
8. Internal mast tangs for the shrouds, headstay or backstay are not allowed.
ARTICLE XI - RUNNING RIGGING
1. The mainsheet must be rigged as specified on the plans at all times. The quarter blocks must always be used in a normal manner, fastened to the top surface of the cockpit coaming. The blocks must be positioned aft of a line projected from the vertical surface of the cockpit seat. A double-ended continuous mainsheet or "head knocker" may be used if the mainsheet bridle system remains basically unchanged. Mainsheet travelers or other systems that control the boom or provide additional leverage are not allowed.
2. There are no restrictions on jib sheeting systems.
3. Down-haul devices on or near the tack of the jib are not allowed
4. Halyards must run externally along the mast. Halyard locks located above the boom gooseneck are not allowed
5. Any form of boom vang is permitted, as long as it is not capable of supporting or lifting the boom.
ARTICLE XII-SAILS
l. Sails for Class racing shall be limited to a mainsail and a working jib. Cloth weight is optional, but three ounce cloth is the minimum allowable weight.
2. SAIL LIMITATIONS:
A. The purchase and measurement of sails shall be limited to one suit per boat in each calendar year. . During the first calendar year of class competition, one additional suit of sails is allowed. In the event of a legal sale of a Cal 20 in its entirety, it's considered that the boat is newly registered and thus in its first calendar year of competition, which permits the purchase of an additional suit of sails.
B. In the case of loss or damage to sails, the owner may petition the Executive Committee for permission to purchase a replacement sail or sails. The owner may also petition the local fleet to use sails to complete a regatta when damage or loss has occurred.
C. A Cal 20 which crosses 36 degrees North Latitude or 135 degrees West Longitude in either direction to compete in an Association Class Championship may acquire an additional suit of sails for that purpose.
3. Fleets shall be responsible for making suitable provisions to govern use of sails in local races.
4. All sails shall be measured and stamped prior to use. They shall be stamped on the starboard tack of the sail by the Fleet Measurer with the official Cal 20 stamp. The Fleet Measurer shall include his initials within the insignia, plus the date the sail was measured, date of acquisition, and the hull number. The Chief Measurer shall issue these stamps to all certified Fleet Measurers. Sails which are not stamped, and have the proper information recorded, shall be considered illegal. The Fleet Measurer shall also keep a record of this data.
5. The Cal 20 sail insignia shall be a 15 inch (outside diameter) letter "C" of a two inch strip width. It shall contain the number "20" in figures six inches high and one inch wide. The insignia shall be placed on both sides of the mainsail between the two upper battens. The Cal 20 hull number or USSA sail number shall appear on both sides of the mainsail below the Class insignia in numerals at least ten inches high.

F. Upper and lower battens shall not exceed 24 inches. The two intermediate battens shall not exceed 26.5 inches.
G. The use of shock cord, or any similar device in place of or in addition to the normal mainsail bolt rope is prohibited.
H. The cunningham hole shall not be more than nine inches from the tack. This is measured from the bottom edge of the cunningham grommet to the bottom edge of the foot bolt rope.
1. An adjustable leech cord to control the leech of the main is permitted.
J. Loose footed mainsails are not allowed.
7. A HEADSAIL is a sail in which the mid-girth, measured from the mid-points of the luff and leech, does not exceed 50% of the length of the foot, and in which any other intermediate girth does not exceed a value similarly proportional to its distance from the head of the sail. Measurements shall be made with the sail stretched sufficiently to remove wrinkles.
A. The maximum width of the head shall not exceed 2 inches. The head shall be construed as a line projected perpendicular from the luff to the bearing point of the head ring to the leech.
B. The luff, measured from the head of the sail to the bottom of the sail at the tack, shall not exceed 20 feet, 2.25 inches.
C. The leech, measured from the head of the sail to the bottom of the sail at the clew, shall not exceed 18 feet, 2.25 inches.

I. The leech of the jib may not be convex.
J. Adjustable leech and foot cords are permitted.
. WHISKER POLE: Maximum length--8 feet, 6 inches, including fittings. When set, the whisker pole shall only be connected to the mast and jib. Equipment or rigging to control whisker pole movement is not allowed.
9. It is the intent of all sail measurements to prohibit any abnormalities or gadgets intended to increase sail area, such as an indentation on the leech at the point of girth measurement. Any deviation from this stated intention shall be cause for disqualification.
ARTICLE XIII - RACING RULES
1. All Cal 20 one-design races shall be governed by the Racing Rules of Sailing (RRS), including the US Sailing prescriptions. If the RRS conflict with Association rules, the latter shall prevail. Local fleet rules shall not apply in inter-fleet races.
2. The 720 degree turn penalty as described in the RRS will apply to all regattas unless otherwise specified by the Class Association.
3. The mainsail shall not be stretched beyond the inner edges of the mast or boom bands.
