I have a catalina 25 and Lowering the mast should be similar to your boat. I made an a frame using rails for the top of a chain link fence. I bought the railing at Lowe`s. I bent the ends slightly so that when I put them together they form an a. I attach the the frame ends to the stanchions with clamps that I bought along with the railing. Where the two ends meet at the top I have a bolt holding the pieces together. Next to the bolt I have a shackle mounted. Start with the a frame laying down on the bow pulpit, attach the jib halyard to the a frame. attach a line opposite from the jib halyard to the forstay with a block to use for lowering . I also built a crutch from a 2 inch square tubing with a roller on the end that I place into the pintles in place of the rudder to lower the mast into. When everyone is ready disconnect the forstay and the forward shrouds and she is ready to be lowered.
