Radio Report from Pi'ikea Miller, Apprentice Navigator on "Hokule'a."

No. of Days at Sea: 7

The navigators corrected their estimated latitude to 10 degrees N at sunrise, based on a good measurement of the altitude of Hokupa'a, the North Star, with Alkaid parallel to Hokupa'a (i.e. when the the North Star is close to the height of the North Celestial Pole). They decided they have been overestimating their speed and distance traveled.

After a day of cloudly, squally weather, choppy seas, and gusty winds, the sky cleared last night at about 9 p.m. Weather today is sunny, with winds ENE at 15 knots.

The back sail was reefed last night to take pressure off the rig.
