No, Alaska and Hawaii do not touch the same specific body of water. While both border the Pacific Ocean, they are separated by thousands of miles and distinct oceanographic regions.
Alaska's vast coastline borders:
Hawaii, located in the central North Pacific, is surrounded entirely by the Pacific Ocean.
Although both states have Pacific coastlines, the "body of water" adjacent to Alaska's southern coast is specifically the Gulf of Alaska (a marginal sea of the Pacific), while Hawaii sits in the open central Pacific. They are distinct hydrological regimes separated by ~3,000 miles. No single named sea, gulf, or bay touches both.
