Purjepinda mõõdetakse sellekohaste mõõtmiseeskirjade järgi kas otse või kaude. Ühemastilistel jahtidel mõõdetakse otse suurpurje ehk groodi pindala. Bermuudagroodi pindala valem:Sbgr=1/2•ab (a - eesliigi pikkus halsinurgast piki masti kuni vallinurgani, b - poomiliigi pikkus halsinurgast piki poomi kuni soodinurgani, purjekumerust ei arvestata). Pikkade, läbi kogu purje ulatuvate liistude kasutamisel leitakse purjepind valemiga: Sbgr=1/2•ab+2/3•AP (A - mõeldav sirgjoon pingutatud purje soodinurgast vallinurka, P - &quot;purjeküüru&quot; kõrgus selle suurima laiuse kohal). Kahvelgroodi purjepind leitakse valemiga: Skgr=Ah+(CD)/2+2/3•AP. Eespurje mõõdetav pindala Se mõõdetakse kaude, selleks on 85% eeskolmnurga pindalast: Se=0,85•1/2•HY (H - kõrgus jahi tekist eespurjetaagi kinnituskohani mastil, Y - kaugus mööda teki pinda mastist eespurjetaagi kinnituskohani). Tegelik eespurjede pindala võib olla kuitahes suur. <br /> <br /> Autor: Enn Oja<br /> <br /> Allikas: Mereleksikon, 1996</div> Enn Oja
