9. El <strong>yate</strong> Sappho <strong>de</strong> Epp = 18,74 m. con CPr = 2,40 y 20 cm. apopado.<br />

∆ = 66 Tns., KM = 3,20, M u = 0,66, KG = 2,40, XF = 0,20(–).<br />

Trasladamos un peso <strong>de</strong> 1.200 Kg. <strong>de</strong> un lugar Kg 1 = 0,8, Xg 1 = 2,5(–) a<br />

otro <strong>de</strong> Kg 2 = 1,8 y Xg 2 = 5(+).<br />

Calcular calados finales, GM final y GZ <strong>para</strong> 8° <strong>de</strong> escora.<br />

Solución:<br />

a × Mu = p × dL dL = –2,5 + 5 = 7,5 m.<br />

GG' = = = 0,02 m.<br />

∆ 66<br />

KG' = KG + GG' = 2,40 + 0,02 = 2,42<br />

GMf = KM – KG' = 3,20 – 2,42 = 0,78 m.<br />
