Dometic's Eskimo Cup won a boating-industry innovation award in 2015 as the first thermoelectric cup holder for boats. The Eskimo Cup keeps drinks refrigerator-cold and can replace most standard 4-inch cup holders aboard. It can hold up to a 20-ounce water or soda bottle and accommodates standard-size soda or beer cans. The cup mounts flush into decks of various thicknesses. It features a built-in drain and an aluminum interior that's corrosion-resistant. Powered by the house battery, the cups can be managed with a single switch or set up with zone switching. They cost $199 each.
