mast
I don't know of too many ready-made mast raising systems for the 23. what you really need to make are a rolling rear mast crutch and solid or wire rope baby stays, with an attachment point in line with the rear pivot for the mast step. These 2 items are a must have. Then, you need the lifting power. One good place to start is the mast crutch - if you use a small winch, and can winch the crutch to make the mast stand up to about 30 degrees, You can really get away with having a 4:1 tackle attached to the jib halyard and simply pull it up. Otherwise, if you are starting from near horiztonal, you need a pole extending from the foot of the mast up about 6 feet. This pole also needs to be fixed so it CANNOT TURN SIDE TO SIDE. I do it myself with a rolling crutch and baby stays. I then hook the mainsheet to the bow, one end to the jib halyard and one end around a winch. I lift the mast from the back of the boat, take up the slack in the mainsheet, then start winching and up she goes.
