As the crisp air drifts over Lake Winnipesaukee and the last of the fall foliage fades from the surrounding hills, lake residents and boat owners know what comes next—winter preparation. The transition from boating season to the long, cold New Hampshire winter isn’t just about saying goodbye to warm afternoons on the water; it’s about protecting your investment and ensuring everything is ready for the next season of adventure. Whether you’re a seasoned lake homeowner or new to the region, properly prepping your boats and docks for winter can save time, money, and headaches when spring returns.
Lake Winnipesaukee’s winters are as breathtaking as they are brutal. Ice can thicken to over a foot in many areas, winds sweep across the open bays, and temperatures regularly plunge well below freezing. This environment creates stress on docks, pilings, and any vessel left unprotected. Because of the lake’s size and varying depths, some coves freeze early while others remain open longer, creating unique challenges for each property owner. The key to winter readiness is preparation—anticipating the conditions before they arrive.
The first and most important task is getting your boat out of the water before ice begins to form. Ideally, this should happen by late October or early November, depending on the year’s weather patterns. Most marinas around the lake offer haul-out services, but those handling their own removal should choose a calm, dry day and ensure all lifting equipment is rated for their boat’s weight.
Once out of the water, the next step is thorough cleaning and inspection. Wash the hull, remove any algae or residue, and check for cracks, blisters, or loose fittings. Drain all water from the bilge, live wells, and engine to prevent freezing damage. If the boat has an inboard or stern drive motor, follow manufacturer guidelines for winterization—this usually includes running antifreeze through the system and fogging the engine cylinders to prevent corrosion.
Fuel tanks should be filled to around 90% capacity to minimize condensation but not so full that expansion causes leaks. Adding a quality fuel stabilizer helps prevent the gasoline from breaking down during storage. Remove batteries, electronics, and valuables before covering the boat, and store these items in a dry, temperature-controlled location.
When it comes to protecting your boat through winter, the right cover makes all the difference. Many Winnipesaukee owners opt for shrink wrap, which creates a tight seal against snow, ice, and moisture. Others prefer reusable canvas covers, which are more eco-friendly and easier to remove come spring. Whatever option you choose, ensure the cover is properly vented to prevent mold and mildew buildup. The frame supporting the cover should be sturdy enough to shed heavy snow and ice without collapsing.
If your boat is being stored outdoors, elevate it slightly off the ground to allow airflow underneath and to prevent moisture from seeping into the hull. Even if the vessel is kept indoors, keep the cover in place to protect it from dust and rodents.
Docks are as vulnerable to winter’s wrath as the boats they serve. Ice movement, strong winds, and heavy snow loads can damage pilings, warp decking, or even pull entire sections loose. The type of dock you own—floating, crib, or permanent—determines the right approach.
Floating docks: These are generally the easiest to winterize. Most owners either tow them into protected coves or remove sections and store them on land. If left in the water, disconnect the gangway and secure the dock in a deeper area where ice movement is minimal.
Crib docks: Built from stone or timber frames, crib docks are more permanent but also more susceptible to ice pressure. Bubblers or de-icers should be installed around the structure to keep water moving and prevent solid freeze-up.
Permanent or piling docks: These require close inspection each year. Check all bolts, braces, and welds for signs of corrosion or looseness. Adding a de-icing system or air circulator can help extend the life of these structures by reducing freeze expansion stress.
Many property owners along Lake Winnipesaukee use bubbler systems, which circulate warmer water from deeper layers to keep the area around docks ice-free. These systems can be especially valuable in tight coves or shallow areas where ice buildup is strongest. Always ensure cords and electrical systems are properly grounded and inspected before installation.
Winter prep isn’t just about the boat and dock—it’s also about the gear that supports your lake lifestyle. Kayaks, paddleboards, and canoes should be rinsed, dried, and stored indoors or on elevated racks. Boat lifts should be raised above the waterline or disassembled and moved to higher ground. Power cords, hoses, and dock lines should be coiled neatly and stored in waterproof containers. This not only keeps them in good condition but also prevents them from freezing to surfaces or becoming tangled under snow.
If your property includes a boathouse, make sure it’s sealed from drafts and pests. Inspect roof shingles, doors, and windows to prevent water infiltration, and consider installing a small dehumidifier or moisture absorber to prevent mildew.
Before the snow flies, take detailed photographs of your dock, boat, and shoreline setup. These will serve as valuable documentation if you ever need to file an insurance claim for storm or ice damage. Make a checklist of everything you’ve done and schedule reminders to inspect your property periodically throughout the winter. Even a mid-season visit to check bubblers, covers, and snow load can prevent major repairs later.
When everything is prepped and secure, you can finally relax and enjoy the quiet beauty of winter on Lake Winnipesaukee. Ice fishing shanties, cross-country skiing trails, and frozen sunsets all become part of the lake’s seasonal rhythm. Knowing your equipment is safe and sound allows you to fully embrace this transformation.
As winter progresses, keep an eye on lake conditions via local updates and webcams. When spring thaw approaches, start planning your reinstallation schedule early—marinas and contractors get busy quickly once “ice-out” is declared. Reviewing your notes from the previous fall makes the spring setup smoother and helps identify any repairs needed before launching again.
Prepping your boat and dock for winter may seem like a chore, but it’s really an act of stewardship—protecting both your property and the pristine waters of Lake Winnipesaukee. Each step, from draining fuel lines to wrapping hulls, contributes to preserving the lake lifestyle for generations to come. The work you put in now ensures that when the loons return and the ice begins to melt, your boat will be ready to glide once more across the mirror-calm water.
