In the days before electricity, light below a vessel's deck was provided by candles, oil and kerosene lamps, all dangerous aboard a wooden ship. A clever solution for the lighting problem was the deck prism. Laid flush into the deck, small conical prisms drew light down below the decks, without weakening the deck planks. The deck prism is an exact reproduction of the Charles W. Morgan deck prism. As America's last wooden sailing whaleship, the Charles W. Morgan is a National Historic Landmark, preserved at Mystic Seaport. Visitors can go below and visit the well-lighted 'tween decks where deck prisms still serve their original function. Our deck prism Measures 4" across, and 4 1/2" high. A lighted base is also available for the deck prism. |
