If your intent is to get to NZ, recommend that you go direct to the Marquesas and spend the hurricane
season there then head
west through French Polynesia
, Cooks, Tonga
and then south next fall. You don't have to hit all the Island Groups but you have a choice. You can hit Hawaii on the way back.
If you want to sail to Hawaii as a shake down, Leave direct from SF. It will be a faster passage
and probably better weather
. Only issue is it stays pretty cold till you get below 25N. Froze my butt off till I was 5 days out of Hilo.
Please, Please, people, put your boat
in your. Knowing what you are sailing makes a big difference on advice
