jrd22 is close. You need to start at Hanalei in late June, early July and and not later than 1 August. 350 deg magnetic or on a close reach starboard tack until you can do true North and continue to Latitude 45 to 47 and keep going North until the wind
is steadily on your port quarter then head
East until you hit land. Your course will look like a big hook with the straight part being your northing out of Hawaii
Don't be so concerned about your course as about the wind
directions you encounter. If you turn toward the coast too early you'll run into the North Pacific
High and be becalmed. That's ok if you have 200 gallons of fuel
but not if you are sailing. Once you start your course East you'll have the wind behind you. Pay attention to the currents when you start heading into the coast. They will push you off course a bit unless you copensate with a bit extra northing.
