Properly winterizing your boat is essential to its long-term survival. The same goes for your RV if you have one. Your dock could probably use a little winter prep before those ice storms hit, too! Even if your area doesn't suffer the bitter winters of the Northern states, you shouldn't neglect winter preparations. According to BoatUS, most insurance claims for boat damage caused by freezing weather actually come from states where freezing temps are unusual. Unlike their northern neighbors, boaters in areas like Florida and California may not even think about freezing winter temperatures. Unfortunately, that unusual (and unexpected) cold snap could result in a cracked engine block or ruptured water lines. Don't risk significant damage to your boat from a freak cold snap, check out Defender's marine water system antifreeze.
Owner's manuals are your best source of information on winterizing your particular boat and its various systems. At a minimum, you'll want to protect your engine and water system (including the head). Expensive electronic equipment may be safer if stored in a temperature controlled, and secure, location for the offseason. Keeping the interior of your boat dry can prevent mold, mildew, and mustiness. Your furnishings will make it through winter in better condition if you prevent excess humidity from building up inside the cabin. Whatever you do to properly prepare for winter will likely save you money, stress, and extra work next spring. It can also mean getting back on the water sooner!
