true for about 80% of the time - the other 20% it can be very rough .. and given the nature of many of its storm (katabtic storms) warning times can be a lot shorter than on the atlantic
also notice that atlantic =| atlantic. the north atlantic and adjactent seas can be very rough (the germann epitath is Nordsee ist Mordsee /north sea is murder sea)- the south atlantic generally is a lot calmer .. (and there advatages to catching a storm way out at sea - no stones to run into)

North Atlantic - there is a reason why the highest Plimsoll marking carries the WNA letters (Winter North Atlantic)

the wooden ships seems to be about as strudy as the early greek / romans one . .the payrus boats seem to be pretty strudy, as long as the payrus does not rot (see: Thor Heyerdahl, Ra 1 + 2)
