Use two similar boats as sheer lifts
On my Hunter 28 (also on Hunter 30s of late '80s and early 90's vintage), the mast step has a flange that fits inside the base of the mast. This means you have to raise the mast vertically a few inches before you can pivot it back on deck. I've had great success by enlisting the assistance of two boats of similar size, tied to either side of your boat. Be sure to rig bow and stern lines with fore and aft spring lines to each of the assisting boats to ensure that everybody stays in position. Rig a bridle that will snub just under your lower spreaders, then attach the main halyards from each of the assisting boats to the bridle. You'll need a crew member on each of the assisting boats to run their halyards to their respective halyard winches, then take up the slack. Now, what has happened is that your mast is supported laterally by opposing forces, just like your standing rigging supports the mast. Use your jib halyard as a substitute forestay to compensate for the lost support when you disconnect your permanent forestay. Loosen the shrouds to allow enough clearance for the mast to raise vertically over the lip of the mast step, then, have your assisting crew to begin hauling evenly on their halyards. The mast should rise vertically, easily clearing the lip of the step. Of course, you will have already disconnected mast light and antenna cables. With a couple of crew members at the base of the mast, you should be able to pivot the base of the mast forward, then the halyard crews can slack tension, as you lower the mast head aft to the deck. I've found that a crew of six performs this safely, and securely: One each at the halyard winches on the opposing boats, two at the base of the mast, and two to guide the upper portion of the mast aft to the stern rail. I've done this in a crowded marina, in gusty conditions, and everything stays centered, in control and secure. Good communication and crew coordination is the key. Good luck.Robert
