Count on two weeks and plan for three. Count on long hours of beating into the wind (not much fun after a couple of days). Count on breaking something that if you can't fix at sea you may be in real trouble. If you plan to come into shore regularily, count on even more discomfort while sailing. And finally, you can probably count on seeing whales and perhaps even getting up close and personal with one as the late summer is when they are migrating to Hawaii from Alaska via the West Coast. (I hit one August 2008 and polished off all of the fresh bottom paint on the leading edge of my keel.)
OR, count on spending some money, driving up I-5, and letting others do the transporting.
