Use a crane
Did my 1890 in the yard using a crane.Remove the sails, remove the boom, loosen the stays, disconnect the wiring. Label everything that you will forget later. Have the shackles or turnbuckles loose enough so you can just pull the cotter pins and unpin the hardware quicklyI made 4 three-legged stands from 2x4s (off center X with a side brace to hold it upright) to set the mast on and work on it.Crane operatore had a fabric sling that we wrapped twice around the mast above the boom hardware. Be careful to have it loose enough to slide up the mast but tight enough to take take the weight when you get to the spreaders.Once the crane takes up the slack, have someone hold on to the mast. It is top heavy and once off the step, it wants to rotate and move. Disconnect the stays at the deck and bungee cord them to the mast just to keep things organized, especially roller furling.I stabilized the mast while the operater lifted it up off the step and then swung it over the side where someone else grabbed it when we lowered it. It was relatively easy to guide into the stands.Once down it is an easy two-person lift to move it. Just bulky. Key was having everything ready, especially a few weeks later to do just the reverse. I prepositioned all the pins and shackles at each deck location before the crane arrived.Preparation pays to keep the crane fee to the minimum. Easy job with a crane.Can be done using two sailboats along side but I preferred keeping my friends.Good luck,Warren Renninger
