You can lift using straps but you must first deflate the tubes and make sure they don't pinch. You don't want to lift boat with tubes inflated as they will compress under the load. You could use stern rings and deflate the bow only then use the bow eye.
Best to use wedges (ex:wood covered with carpet) and keep the straps away from the tubes. They may get severely pinched and leak without showing any obvious damage. The air will track and escape at a the end of a near seam, sometimes much later .
Difficult to find .Hard to repair.
