Boat Shrink Wrapping: 6 Checks Before Winter Storage

When the last trip on the Chain O’Lakes is over, there’s still some preparation to do before your boat is ready for winter. A properly fitted cover helps keep weather and debris out, but the condition of the boat underneath it matters just as much.

Before your boat gets shrink-wrapped, here are six things worth checking.

1. Start with a clean, dry interior

Remove food, trash, wet towels, and loose gear. Check beneath seats and inside storage compartments for moisture that may have gone unnoticed during the season.

Clean surfaces with products suitable for your boat’s materials, then allow everything to dry thoroughly. Washing the boat immediately before wrapping can leave moisture behind in carpet, upholstery, and compartments.

When practical, take removable cushions, life jackets, and other soft items home. Clean and dry them before putting them in a suitable storage location.

2. Make sure the cover can breathe

Proper ventilation is an important part of shrink wrapping. Moisture can collect under a poorly ventilated cover and contribute to mildew, even when the outside of the boat looks well protected.

Vent placement depends on the boat’s size, shape, and layout. A pontoon, runabout, and cabin boat may need different arrangements. Vents also need to remain clear throughout the winter.

Moisture-control products may help in some situations, but drying the boat and providing ventilation should come first.

3. Check the support and wear points

A winter cover needs suitable support to help shed rain and snow. Low spots can collect water, and accumulated weight can strain both the covering and its supports.

Windshield corners, rails, sharp edges, and accessories can rub against the material. These areas need protection, and the support arrangement should avoid damaging upholstery or fittings.

Shrink wrapping also involves specialized heating equipment. Because improper use can damage a boat or cause a fire, have an experienced installer handle the work.

4. Complete winterization before covering

A shrink-wrapped boat still needs proper winterization. The covering will not keep an engine or onboard water system from freezing.

Confirm what has been serviced before the boat is closed up. Depending on the equipment, preparation may involve the engine, drive, plumbing, livewells, washdown equipment, and other systems that hold water.

Procedures vary by boat and engine model. Follow the manufacturers’ requirements and discuss the scope of work with your technician. Arrange needed maintenance or inspections before the cover makes access more difficult.

5. Plan for access and winter checks

If you’ll need to get inside the boat during storage, discuss an access opening with the installer before wrapping begins.

Check the covering periodically, especially after heavy snow, rain, or strong winds. Look for tears, sagging areas, loose material, blocked vents, or water collecting on top.

If something needs attention, contact the installer or storage provider. Avoid climbing onto an icy boat or working beneath an overloaded cover.

6. Choose the services you want completed

Before scheduling, discuss which services you want completed, such as winterization, shrink wrapping, or needed maintenance. Baltic Marine can recommend preparation based on your boat and planned storage. You choose which services to authorize, and we confirm the agreed work before starting.
