and no, the Kon Tiki was based on a South American boat style,
No one was speaking about Kon Tiki, but about Ra 2.

not an egyptian one. the style of sail, the shape of th bottom is different, even the details of construction are different. if you cannot even get that detail right, I dunno what to say to you.

I already posted links above to the image of Egyptian boat of Heyerdal

EDIT: Thor was trying to prove that south Americans settled in Polynesia; Kon-Tiki is an old inca word for the sun god. here is an article: http://www.solarnavigator.net/history/kontiki.htm . and as I misspelled the name, I have corrected it in this post.

what that has to do with the kon tiki's construction itself is beyond me, since my comment then was about how you specifically stated the kon tiki was of egyptian design;

what that has to do with the kon tiki's construction itself is beyond me, since my comment then was about how you specifically stated the kon tiki was of egyptian design; either way, they are irrelevant to the debate, as the construction technique, donnage, transportation means, and even the reason for the voyage, are different from a hypothetical roman galley.

you don't get it, do you? a roman galley is not the kon tiki
I never said Kon tiki was of Egyptian design. I don't know why you are speaking about his Pacific Ocean expedition when I was speaking about his Atlantic expedition on the Egyptian boat Ra 2.

none address the structural problems of Roman galleys (the typical ship of the Roman era)

I'm aware of these: and again, none address the structural problems of Roman galleys (the typical ship of the Roman era). to my knowlege, none are 90ft+ in length; none have length to width ratios of 7:1 or more; and none have crews of almost 60 or more, all of whom involved in strenuous, 24 hour activities (i.e, the oarsmen), or coordinating the activities of these men. lastly, none of the above, in consequence of lacking the type of crew a Roman galley has, lacks space enough to store dunnage in their hold to feed every member of the voyage.
1) See above posts about ships.
2) They could always use Egyptian boats or bull-skin boats ;-)

By the way Mediterranean in winter hosts often storms and big precipitations, and in summer, yes it is quite. Also Magallanes when he crossed Pacific Ocean faced no storm and called it “Pacific”. But it was just luck. Who said ancient Atlantic travallers couldn’t have such luck too? Azores are pretty deep into the open Ocean. If the galleys didn't crack on the way to Azores, it makes me think, they can survive the whole journey.

Accident – I really can’t get how the archaeologists start digging in America and accidentally found Roman statue in the tomb of 13-15 century? (Garcia Payon J. Una cabecita de barro, de extraña fisionomia // Boletin del Instituto Nacional de Antropologia e Historia. — México, 1961. — № 6. — P. 1—2.)

Coincidence – what do you mean exactly? Accidently Indigenous peoples of America in Middle Ages or in ancient era produced exact things as Romans done?
