Keel
Hunter designs and builds their boat keel to support the entire weight of the boat. Jack stands need to be used around the boat hull to keep her stable. Quality yards should know this routine. Perhaps you should ask the lift operator and/or crew to verify this process. Your boat will need a stand at the bow and stern, plus at least three on each side of the hull spaced evenly. The keel should rest on wooden blocks placed in about the center of it.
