I still don't understand why one would want to sail around the world since you are already here, however, It seems to me, if you just hug the coast line
real close it would be a lot safer. As I look at my atlas, I see you can practically drive to England from the East coast of the states via Nova Scotia, a short hop to Green Land, Ice land etc. I don't sea any place on my Globe that has a very big distance of open ocean from a Land mass if you follow the contours. like all the white colored land on the top and bottom of the planet. Why all these big ocean crossings are so popular I can't fathom. Look at the Pacific, just cross from Siberia to Alaska, I hear you can see one from the other. Saftey first at sea I say.
