The closest to that that we have done, was in a 36 ft. mono, and was from Bora Bora
to SF, via Hawaii
. You could have a pretty pleasant sail from the Marquesas
to HI, with the SE trade
winds predominating. Then you could go motoring through the Pacific High to Mexico
. Carefully check about the distance involved. You can re-fuel in HI, and water
up again, that's no problem, and you might catch the odd sailing breeze along the way. For us the HI to SF leg was a long one, but it has a longer time of northing than what you contemplate. If you haven't actually calculated your average days' runs against the trades, you should assume that it will take you about 50% longer than anticipated.* You can always be pleasantly surprised if you do better, but the consequences for over-spending your fuel
at the beginning, could be pretty dire. Meal times can be the height of the day on long passages. Fwiw, going the other way, with the wind
, from Cabo to the Marquesas, in the vessel above, took us 22 days, iirc., on a boat
that averaged 140 n. mi./day. We did motor
crossing the ITCZ when the wind
failed, but very little motoring.
Expect stuff to break during the passage
, it will be a long, difficult voyage. Good luck with it.
*This is kind of a nuisance because it means all stores, food
, water and fuel, but it is conservative and safe.
