A sealed vessel with a vacuum inside weighs less than one with regular air. Theoretically, assuming a zero-weight vessel, would the vessel float like a helium balloon? If so, is it possible to actually build a vessel that is strong/light enough to float?

A vessel with a vacuum applied weighs less than one with air in it. Theoretically, would a zero-weight vessel with a vacuum inside float in the air? If so, can we actually build a vessel that is light enough and strong enough to float?
