E. Sails: 1. General: a. All sails must measure within the specified limits of the official sail plan when first measured. (1) Light sails shall consist of spinnaker only. Maximum dimensions shall be as follows: Luff 21', Leech 21/, Foot 16'. The choice of using the working or the overlapp­ing jib is optional. (2) The maximum dimensions of the working jib are: Hoist 20', Leech 17'6", Foot 7'. (3) The maximum dimensions of the overlapp­ing jib are: Hoist 20', Leech 17'9",, Foot 8'6". (4) The maximum dimensions of the mainsail are: Hoist 27'6", Leech 28'9", Foot 13'. Maximum girth 7'6". b. If it becomes necessary to measure sails after they have been in use and have previously been measured in and approved, certain allowances for stretch shall be made. The amount of the stretch allowance is shown under the respective sail. c. There shall be no restrictions upon the type of material used in the fabrication of the sails. d. The method of measurement shall follow the instructions given under the title "Sail Measuring Procedure." e. Accredited sails shall be used in all Season Championship races and such other races where Bear Class Rules are specified or Bears race as a class." 2. Jib: a. Battens may be used not to exceed three in number and each batten shall not exceed 14" in length. b. The total stretch of foot plus leech shall not exceed 4" over maximum specified dimensions. 3. Mainsail: a. The number of battens shall not exceed four and in such case the maximum lengths of the upper and lower battens shall not exceed 28", and the intermediate battens shall not exceed 32". b. The width of the head board shall not exceed 6". 4. Spinnaker: a. A maximum stretch of 6" total for the combined luff, leech, and foot is allowable. b. Only one spinnaker may be used in any one race. 5. Sail Measuring Procedure: a. All girth and leech measurements and the foot of the overlapping jib are to be measured while drawn hand tight with about 5 lbs. tension. (1) The hoist of mainsail and jibs, and the foot of the mainsail and club jib are to be measured while stretched out on the spares to the "final length" of the sail. The "final length" is defined as the condition when all puckers in the sail are stretched smooth. This is the made length of the sail and is the optimum amount of stretch for normal sailing. (2) When new sails are ordered, the location of the goose neck tack pin in relation to the mast and top of boom must be supplied to the sail maker along with the thickness of any track battens. Where the tack pin is misaligned, sail measure­ments will be taken to the point where the sail would extend if the tack pin was in alignment. (3) The local measurement committee man must be notified when new sails are received, and certification must be submitted to the class secretary. b. Jib: (1) Measure to the point of the leech and foot edges with the luff. (2) Two girth dimensions - from intersection of bolt eye to mark 8' down the luff and the leech - this not to exceed 44". The other from intersection of bolt eye to a mark 13' down the luff and the leech. This not to exceed 70". c. Mainsail: (1) Head of mainsail - center of hoisting eye in the head board. (2) Other points on mainsail - tack and clew out haul: measure to the point of intersection of the two intersecting edges. (3) Bias or girth measurement - Determine the midpoints on the luff and leech by folding the sail, first on one edge and then on the other. Measure the girth through these points using the outside of the luff rope and the after end of the leech as the extremities of the measurement.
