You cannot
head direct to the islands from the NW unless you have plenty of
fuel. The Pacific high is a no
wind area that is about level with SF in the summertime.
Head SSW till your below the latitude of SF, 38 degree latitude then rhumbline to paradise. The high wanders around so if wind begins to fail head south till it picks up again.
Be aware of hurricanes generated in the Gulf of
Panama. They often head west especially early in the summer. They mostly stay south of 20 degrees latitude and are easy to avoid if you are patient enough to hang out north of their path till they pass.
The trip back can be more exciting but is actually a shorter sail for you Salish Sea denizens than those heading further south.
