Starting Saturday, tourists were allowed to view images of the inside of the second boat pit from a camera inserted through the a hole in the chamber's limestone ceiling. The video image, transmitted onto a small TV monitor at the site, showed layers of crisscrossing beams and planks on the floor of the dark pit.
"You can smell the past," said Zahi Hawass, director of Egypt's Supreme Council of Antiquities.
Experts will begin removing around 600 pieces of timber in November, said professor Sakuji Yoshimura of Japan's Waseda University, who is helping lead the restoration effort with the antiquities council.
The discovery of the boat pits more than 50 years ago by workmen clearing a large mound of wind-blown debris from the south side of the Great Pyramid is considered one of the most significant finds on the plateau. They are the oldest vessels to have survived from antiquity.
The reconstructed ship is on display in a museum built above the pit where it was discovered. It is a narrow vessel measuring 142 feet with a rectangular deckhouse and long, interlocking oars that soar overhead.
The cedar timbers of its curved hull are lashed together with hemp rope in a technique used until recent times by traditional shipbuilders along the Red Sea, Persian Gulf and Indian Ocean.
The unexcavated boat, made from Lebanese cedar and Egyptian acacia trees, is thought to be of similar design, but smaller and less well preserved.
John Darnell, an Egyptologist at Yale University, said new research into the second boat could fill in some blanks about the significance of the vessels and help determine whether they ever actually plied Nile River waterways or were of purely spiritual import.
