Not so much hull "failures" as "soft spots" and problems. Think about it - the entire boat weight sitting on four, roughly 1-inch square, spots on your hulls. Probably not the best thing with any boat of any weight. That's how mine came and I made four foot-long cradles by cutting and 18-inch scrap piece of sewer pvc pipe in half, bolting a galvanized bracket to the bottom and lining it with indoor/outdoor carpet. Same piece as the from the storage tube. Probably cost all of $50 and a half-day's work.
