Sail Measurement Points
| Jc | The horizontal distance from the foreside of the mast at the deck to the tack point on the forward end of the bowsprit pole with the bowsprit pole extended to its fullest length, or to the end of an oversize symmetrical spinnaker pole. |
| I | The vertical distance from the top of the Jib sheave to the shear line abeam of the mast. |
| Ic | The vertical distance from the top of the Spinnaker sheave to the shear line abeam of the mast. |
| P | The distance from the top edge of the boom to the lower edge of the measurement band or mainsail sheave |
| E | The distance from the aft edge of the mast to the inner edge of the measurement band on the boom. |
| SPL | The length of the symmetrical spinnaker pole when measured from the forward edge of the mast to the end of the pole. |
| BPL | The length of a “bowsprit pole” used with asymmetrical spinnakers when measured from the forward edge of the mast to the tack point of the extended pole. |
| ASMW and SMW | Sail width shall be measured with such tension as will remove wrinkles along the line of measurement. |
| LP | The perpendicular distance to the luff from the luff to the clew of the headsail. LP can be difficult to measure if you have a problem measure the foot length & so note on entry form. Or give Mike Danielson a call for help 044 322 145-6418 |
