The Caribean 600 is a zig-zag route, I therefore rigirously planted my waypoints to have either headings toward the prognosis of wind direction for VMG or straigtest possible route thru the isles.
And indeed zoomed in to get them buys right and not inland on an Island. Now all of a sudden my boat is on ground. WTH!
What kind of a weypoint is one, that you miss by miles off, when closing in in constant wind?
