Glass-bottom Boat
A glass bottom boat is a boat with sections of glass, or other suitable transparent material, below the waterline allowing passengers to observe the underwater environment from within the boat. The view through the glass bottom is better than simply looking into the water from above, because one does not have to look through optically erratic surface disturbances. The effect is similar to that achieved by a diving mask, while the passengers are able to stay dry, out of the water.
Famous quotes containing the word boat:
“The almost unexplored Everglades lay close by and with a half- hour’s start a man who knew the country was safe from pursuit. As one man cheerfully confided ..., ‘A boat don’t leave no trail, stranger.’”
—For the State of Florida, U.S. public relief program (1935-1943)
