Or... you could dig a 33' deep trench and turn the boat upside down. That way, you could swing (or hang) the mast into place. Then all you would have to do is get a crane to pull up the boat and somehow swing it around 180*.

Or, if the trench was long enough (40' est.) you could get about 10 people to help rotate (right) the boat from upside down to right side up.

But in my opinion... If the mast is to heavy for you to handle solo, I would ether get a helper on the tramp to help me walk it up, or on a safety line pulling the halyard, or purchase an Easy-Step Mast Stepper from Murrays.com.
