Finding the optimum position for the central lift ring takes some experimentation, so your harness lines, at least initially, have to be adjustable. Because the weight of an outboard naturally makes the dinghy stern heavy, the lifting point needs to be well aft of center to compensate. If you use a direct halyard rather than a boom crane, it lifts the dink at a slight angle rather than pulling it straight up. The lifting ring, then, must be offset athwartships over the dinghy, toward the mother ship, by a couple of inches. Set up what seems about right, lift your dinghy enough to clear the water, and look at how it sits. If the stern hangs dramatically lower than the bow, lower the dinghy and reposition the lift ring a little farther aft by adjusting the harness lines. If it hoists bow down, shift the ring forward. Make small adjustments. An inch or two can make a big difference.
