July 25, 2010
Sailing from Emerald Bay, Catalina, To King Harbor Departed at 1300 seas flat (2 foot swell) on the beam, long period swell.
Hull and prop are clean
Backstay tension was in about 2" ABOVE the black tape mark (i.e. light air tension) (i.e. normal furling position)
Headstay somewhat loose, good for light and ready to furl main if needed
Starting out with staysail and main, solid running backstay tension, added jib later as wind lightend away from Catalina
Heading 350M COG 354M
