Winter Boat Storage in Seward, AK: A Guide to Protecting Your Vessel Through the Harsh Alaskan Winter
For boat owners in Seward, Alaska, the end of the fishing season and the stunning fall colors signal a critical task: preparing your vessel for winter storage. The unique combination of Seward's coastal location on Resurrection Bay, heavy snowfall, freezing temperatures, and powerful winds demands a specialized approach. Proper winter boat storage here isn't just about convenience; it's an essential investment in preserving your boat's integrity, safety, and value for the next season of exploring Prince William Sound or chasing halibut.
The first and most crucial decision is choosing your storage location. Given Seward's extreme weather, indoor, heated storage is the gold standard, especially for fiberglass boats susceptible to freeze-thaw damage. Several local marinas and dedicated storage facilities offer this option. If you opt for outdoor storage, which is more common and often more affordable, a high-quality, professionally fitted cover is non-negotiable. Ensure it's rated for heavy snow loads and is securely strapped to withstand the notorious winds that funnel down the bay. Never use a tarp that traps moisture; breathable, reinforced marine covers are a must to prevent mold and mildew.
Your pre-storage checklist is your boat's best defense. Start with a meticulous freshwater flush of the engine and all systems to remove corrosive salt from Resurrection Bay. Completely drain the engine block, manifolds, and any water lines. Add marine-grade antifreeze to plumbing systems and heads. For fuel systems, top off your tank with stabilized fuel to prevent condensation and phase separation, running the engine to circulate the treated fuel through the lines.
Remove all electronics, fishing gear, life jackets, and any other valuables. Moisture and freezing temperatures can destroy electronics and promote mildew on fabrics. Prop open hatches and lockers slightly to encourage airflow. Place moisture-absorbing desorbers or buckets of desiccant inside the cabin to combat the damp coastal air. Don't forget to disconnect and remove the battery, storing it on a trickle charger in a dry, frost-free place.
Finally, consider the local environment. Seward's significant snowfall means you or your storage provider must have a plan for safely removing snow from your cover to prevent collapse. Check on your boat periodically throughout the winter if possible. By taking these proactive steps for winter boat storage, you're not just parking your boat; you're ensuring it's ready, reliable, and safe for when the ice recedes and the long Alaskan days return, calling you back to the water.
