Re: Pacific Crossing

I imagine your route will depend on weather and time of the year. One of my favorite references for voyage planning is Jimmy Cornell's "World Cruising Routes". We also use Predict Wind.

Safe Travels

Re: Pacific Crossing

Usually a little south of rhumb line is more wind, a little north is more positive current. Suggest you sign up for the free weekly Metbob Weathergram. Here's his note for this week
Quote:
From Galapagos area to Marquesas, departure can be any time this week. Best path for wind and current is to motor/sail to 4 South 95W, then sail to 6S 127W and then go direct

Re: Pacific Crossing

It's quite interesting to me that the ITCZ is typically WELL north of the equator, except for a few weeks around January. This means a Galapagos-FP passage will probably miss the heart of the doldrums and spontaneous boat-washes of the ITCZ.

Re: Pacific Crossing

When we sailed that route years ago, we just blindly sailed the rhumb line and covered the distance to the Marquesas in 25 days. But now, crossing the Indian Ocean, we splurged and got Predictwind Offshore, coupled with the satellite "Iridium Go!". With the Predict wind, we get up to date ocean current information. That ocean current information was extremely helpful recently working our way from Sri Lanka, across the equator, to Chagos then on to Rodrigues. Check around and see if any in your crossing group has the Predictwind, ocean current application.

The ocean current prediction model (RTOFS) is updated once a day. You can get it from most any GRIB provider, like SailDocs.

Its in the bottom left dropdown menu on the grib page......

Looks very basic but hover over a location and you get to see speed, direction, and sea temp...

It was a new one for me as well....
