Depends on what you are asking.
I keep my boat in a slip. From the time I decide to drop the mast to the time it's placed with the boom and sails still on, on the pulpit, around 20 min. That's in the water and leaving it there. About the same to raise it and pull all the extras off (gin pole, side stays ect.) BUT, there is a lot more to do to secure the boat for a trailering and get it ready from that for a sail. That's where the extra time comes in.I did it the first time by myself after watching someone do it on their boat first. In reality for the simple act of raising and dropping, the extra person is a safety. Connecting and disconnecting all the stuff, well nice to spread the pain around. alan
