Hi Someday and welcome to the forum,
I will answer this assuming you're asking a serious question and not trolling or joking.
First, you are asking the nautical equivalent of "I'm in Seattle
and I want to fly Delta
Airlines to the Galapagos, have lunch and come home."
If you have done some day sailing
you must have some idea of how fast a sailboat goes. If the Galapagos is your dream vacation then you must know where they're located.
Without getting out charts
and actually measuring it's roughly 4000 miles. For rough voyage planning use a rule
of thumb of 100 miles per day so an absolute bare minimum of 40 days non, stop, one way. I would figure more like 50-60 days. Ignoring seasonal weather
issues (summer hurricanes and winter storms) figure 5-6 months for the trip.
Coming back you will be sailing against the wind
and currents if you go up the coast so plan on sailing via Hawaii. Considering the overall time involved you may run into problems with weather
seasons. Summer hurricane
season and winter storm season. You should sandwich an ocean voyage in this area between those.
? If you don't plan on stopping and nothing breaks that forces a stop for repairs
then the cost is only for the food
you eat on the trip. Once you reach the Galapagos then budget will depend on where you stay (expensive marina or anchor
for free), if you apply for permits to visit the marine
reserve areas, if you cook on board or go out every night.
Nothing wrong with dreaming but the plan as you put it currently doesn't really work. It would be far more practical, cheaper, comfortable and over all enjoyable to fly to the Galapagos for two weeks than to sail.
