We have a Catalina 27 Tall Rig (so I think that's 2' longer than yours), and have had the mast down numerous times for re-wiring, new masthead, installing VHF antenna on top, etc.
Two adults can carry it pretty easily. I would estimate the weight at about 100-110 lbs. It would be pretty difficult to move, carry, or maneuver with just one person.
We raise and lower the mast with an A-frame made out of 2x4s. Works great, but is scary!!! I can send you a link to the plans for building this if you'd like.
Good luck.
