I have all the blocking, planks, and plywood pads from my boats blocking, no longer storing boat at home. Used for 2 different boats over the years, a 27’ Pursuit and a 31’ Chaparral. 24x cement blocks from masonry yard not Home Depot plus an extra block just in case, 2x 10’ pressure treated planks, and 6 3/4” pressure treated plywood pads with two extra. Over $200 in material if you buy new.
