ok grazie Albert.
Su un vecchio regolamento specifico Orc Club ho trovato questo:

Longest Perpendicular of Jibs (LPG).
1. Jibs shall be measured on the perpendicular from the luff (outside edge of the sail
and/or luff rope) to clew (intersection of the lines of the foot and leech.
2. LPG shown on the rating certificate shall be the largest such dimension found on the jibs
carried on the yacht.
3. Jib Roach (JR), where permitted (see 811.2 (b), shall be measured as the maximum excess
of the three girths as defined in 812.1. JR multiplied by 1.5 shall be added to LPG for the
purpose of calculating the sail area. An excess in any of the girths shall not exceed 10%
of the maximum defined in 812.1.
