Hey. Haven't been on in a while, and I won't be able to for another while, but here's my thoughts.
I don't know about any Thor Heyerdahl trip from Egypt to SA - I read his book about the Kon-Tiki trip, from somewhere in Africa to SA or SA to Easter
Island or something like that. My point is this journey took place totally in the so. hemisphere. There could be more though.(My uncle stole a knife
from that boat

)
Also, did you guys know the Chinese built wooden sailing vessels that were as BIG as CRUISE SHIPS?! yup. they weren't really practical - their
purpose was to intimidate enemies into defeat. but its still pretty cool
