One Block under the forward section of the keel.
Draw an imaginary line from the furthest aft section of the keel where it meets the hull down to the bottom of the keel ... second block under the keel goes forward of the imaginary line. If any blocking is aft of this imaginary line, the hull will deflect and buckle.
4 jackstands placed at the bulkheads
2 vee poppits - one at the bow and one placed between the rudder post and prop strut.
