July 23, 2010
Sailing from King Harbor to Isthmus, Catalina, Departed King Harbor at 1550 and motored to the R10 bouy (1630), note that seas were very flat (1-2 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
Heading 176M COG 175M

Prior to this point running backstay tension was light to prevent pumping, now tensioned to normal rigging tension to support staysail
