You get sunburned like everybody else, the only difference is it's more of a byproduct of boating than a tanning bed neccessity. Stock up on some boating-specific sun tan lotion for a winter vacation or the next boating season with Shurhold Industries' SPF 44 Sunscreen. The sunscreen is custom-made for boating conditions, holding up to eight hours' worth of waterproof protection. It's water-based, so even a little sand won't stick to your body because of the lotion. It's available in 2-, 6- or 32-ounce bottles, or you can get a season's worth with a 1-gallon pump container. Prices start at $5.50.
