"2. Wait for a good THREE day forecast with light winds and relatively calm seas and do it!! Program in GPS waypoints for all possible harbors along the way in case something goes wrong. If you make it to Newport Beach in good shape...don't forget to check the weather on your VHF again before you leave the next day."
My god are you trying to kill them? From my years on the west coast the moneys on them being more wrong than right predicting the weather! LOL
Good advice here. Also you might want to check your OB and tank for ethanol damage. Hoses, tank fittings and motor ect. prior to leaving.
