Egyptians in the New World?

[Sean Manning]

Thor Heyerdahl, a Norwegian ethnographer and adventurer, proved with the Ra II, a ship that he and several others modeled after drawings and models from Ancient Egypt, that it could have been possible for the Ancient Egyptians to cross the Atlantic from Morocco to Barbados by sailing with the Canary Current.
Although most of his findings and experiments, including this one, weren't accepted in the scientific community does anyone believe this could have been a possibility? Also, even though other members of the forum already discussed the possibility of Romans discovering the New World, does this help prove that they also could have made the journey across?
Any feedback is welcomed.
all the information that I based this on: http://en.wikipedia.org/wiki/Thor_Heyerdahl

As Jona says, we have to be careful about things which are possible but which have noevidence for them. But I'm not certain Ra II proved what he thought was possible was possible.

People who I respect have told me that the right type of reeds to make a boat don't (and didn't) grow in northwest Africa (Heyerdahl had to truck his from Lake Chad or boat it in from Bolivia and launched from Morocco). Reed boats suffer from waterlogging over time, and wear out from wave action on open water, so its unlikely that a boat launched in Egypt could have made the crossing.
