Sometimes a boat is just a boat, and there are endless illustrations of boats associated with funerary services. BTW, there is a second boat aside the great pyramid, discovered at the same time as the first, but in very bad condition. They have been restoring it for several years now.

Here, the ‘solution’ is much more complicated than the problem. Lifting millions of gallons of water, as well as the boats, to a progressively higher pyramid does not seem to be a practical solution to the problem of one boat lifting one block at a time up the pyramid. In looking at the illustration of the partly raised great pyramid, a rough calculation reveals that perhaps 5 million gallons of water would have to be lifted to that level to create the pond, as well as the waterproofing of the stone walls and floors to prevent leakage as the height was raised. Also complicating the waterproofing is that the interior blocks are roughly shaped, not square and having true surfaces. And while the amount of water needed would be progressively less as the height was raised, each floor level or second level higher would have to be waterproofed!

Herodutus states that he was told by local officials the traditional explanation carried down through history was that the blocks were lifted by moveable cranes progressively up the stepped sides of the pyramid. There are also illustrations depicting the transport of blocks on level ground or up inclines simply by pulling them with gangs using ropes. Even huge statues were moved that way, as the illustration in the tomb of Djehutihotep reveals.

There are calculations for the movement of objects over level ground and grades here:

The boat is a large lever. The fulcrum is bottom center, the fulcrum moves on the curved bottom. Push up on one end and pull down on other end. Swivel the boat and repeat ptocess. It can move on land.

Hi Istvan, this is an interesting concept. I've been looking at Minoan technologies around this time which traded with Egypt. The Minoan hulls seem to be advanced, see: http://www.ancient-origins.net/history/3500-year-old-advanced-minoan-tec...

Minoans used strong mortise and tenon joints (can't tell from the reconstruction of the Khufu boat - but there aren't any holes for rope fixing, so probably did the same) and linen with pine resin to provide a watertight composite hull for long voyages, dramatically improving seaworthiness. There is probably more to this relationship, for example, they supplied architects for most of the mainland palaces around the med, they were experts in water tech (viaducts, water storage, townwide communal plumping, steam rooms, etc). The archaeology supports your theory, they used canals around the pyramids. The lifting is an interesting concept, they were using ships for transporting masonry, so will have needed a method of lifting them – not seen any examples of block and tackles around this time, so you may be right! I believe the Minoans that dominated the shipping lanes in the med may have used this technique, not for lifting, but to sink foreign vessels that resisted boarding. E.g. if they attacked with stand-off weapons (arrows and slings), drive into the foreign hull amidship, forcing the foreign hull to list, so she would take on water. The Minoan composite hulls would be lighter, faster and more manoeuvrable to achieve this.
A thought, to counterbalance the block at the front end, they could lift water ballast at the backend! Assuming a fulcrum around the 1/5th of length, they would need to lift 1/5th the weight in water at the back to balance the boat. They could use leather bladders to do this and there are blocks at the backend so they wouldn’t slide down the hull! They could then dump this ballast after delivery for the return leg to pick up the next load. I think your theory may be correct, they didn't have block and tackles for lifting and would have needed a method to load and unload blocks.
