Here's another proven Pacific crossing design...
You will find that if you follow the original approach that fitting out will be very reasonably priced.
I have included full information for you to either create such a vessel yourself or have it done by competent craftspeople.
Note that many of them went thousands of miles across the Pacific with minimal crew and navigation
instruments. It is reliably reported that they used none of the following: radar
, electronic depth sounder
or gasoline engine
, chronometer, chart plotter, GPS
, etc., etc.
Pay no attention to all those threads telling you that you need all that stuff! All you need is a true connection to the sea and the sky!
