There are lots of videos on YouTube and other information on the web about unstepping a mast. This one is pretty good.

I hope you're not thinking you can unstep the mast without a crane or gin pole.  This is possible on many small trailerable sailboats but would be a highly dangerous disaster on a C34.

If you succeed in the first step, make sure that you have a cradle to place the mast on top of the boat.  At least 3 supports.
