I just took a look at the "hop" from Cocos Is. to the Carolines, to English
Harbour. That is a distance of approximately 4,220 n.m., in a region of not very strong winds. If you select that route
, you want a really good light air sail, and you may need to carry additional fuel
, and you might want to enquire if there's anywhere in the Carolines where you could top off again. If you are cruising, there would be an opportunity to stop at the Galapagos
, and then head
north and west, if that suited you. Some interesting stops along the route, but last I heard, there were pirate problems in the vicinity of Cocos.
