Sun Tracker Boat Cover: How to Choose, Measure and Fit One (7 Steps)

Updated November 2026

A sun tracker boat cover protects your aluminum or fiberglass boat from UV rays, rain, debris and dew when it sits on a trailer, in a driveway or at the dock. This guide walks you through choosing the right size and material, taking accurate measurements, fitting the cover correctly and caring for it so it lasts multiple seasons. By the end, you will know how to pick a cover that fits your specific Tracker model and how to keep it secure in wind.

Why Sun Tracker Boats Need a Dedicated Cover

Sun Tracker boats are sold in a wide range of lengths and hull styles, from small fishing boats to larger pontoon-style models. Covers are cut to the boat’s length, beam and windshield or console profile, so a generic tarp rarely seals well or drains properly. A cover that fits closely reduces flapping, which can chafe gelcoat and scratch windshields over time. It also keeps the seating and console dry, which slows mildew and cracking in vinyl and upholstery.

Step 1: Identify Your Exact Model and Configuration

Start with the model name, year and layout. Tracker owners often find that two boats with the same length have different console heights, bow rails or outboard mounts, so the model name matters more than a rough size estimate. Note whether your boat has a bimini top, a T-top, a T-top with a rod holder or a bow-mounted trolling motor, because these add height and shape that the cover must accommodate.

Step 2: Measure Your Boat Accurately

Measure at the widest and longest points, not just what the brochure lists. Covers are usually sized by overall length and beam, but the fit depends on the shape of the bow, the stern and any raised structures.

1. Length: measure from the tip of the bow to the back of the transom, following the hull curve if you can.
2. Beam: measure the widest point of the hull, typically across the gunwales.
3. Height: measure from the deck to the highest point, such as a console, windshield or T-top, and note the height of any bimini.
4. Outboard: measure the motor’s height and width if the cover extends over it, since many covers include a motor cover section.
5. Trailer: if you store the boat on its trailer, measure the trailer’s length and tongue position so the cover does not interfere with the hitch or lights.

Compare your numbers to the manufacturer’s size chart. Manufacturers typically specify a length range and a beam range for each cover size, so choose the size whose range includes your measurements. When your boat falls between two sizes, most makers recommend the larger one for easier fitting, though an oversized cover can flap in wind.

Step 3: Choose the Right Material

Most sun tracker boat covers are made from solution-dyed polyester or polyethylene fabric. Solution-dyed material holds color longer under UV exposure, while coated fabrics with a water-resistant or waterproof layer shed rain better. Look for a breathable design or built-in vents if you live in a humid climate, because trapped moisture can lead to mildew underneath.

Material feature	What it does	Best for
Solution-dyed polyester	Resists fading from UV exposure	Sunny, year-round storage
Water-resistant coating	Sheds rain and surface moisture	Open driveways and docks
Vents or breathable panels	Allows airflow and reduces condensation	Humid or coastal climates
Reinforced seams and grommets	Holds up to tie-downs and wind	Windy or exposed sites

Step 4: Decide Between Fitted and Universal Covers

Fitted covers are cut for a specific model and typically sit snugly with minimal slack. Universal or semi-custom covers use length and beam ranges, so they fit several boats but may leave gaps at the bow or stern. For a Tracker with a distinct console or T-top, a fitted cover usually gives cleaner coverage. If you own a pontoon-style Sun Tracker, the sizing and support rules are different, and Sun Tracker Pontoon Boat Cover: How to Choose, Fit and Care (2026) covers those specifics.

Step 5: Install the Cover Correctly

Install the cover on a dry, calm day to avoid trapping moisture and to make the fabric easier to handle.

Preparation

• Rinse the boat and let it dry, so no debris or grit gets trapped under the cover.
• Remove loose items such as fishing rods, cup holders and gear that could scratch the windshield.
• Lay the cover out flat and locate the front, back and any vent or tie-down points.

Fitting Steps

1. Place the cover over the bow first, aligning the front edge with the bow.
2. Pull the cover back evenly over the hull, keeping the sides centered.
3. Secure the front straps or hooks to the bow eye or trailer frame.
4. Adjust the sides so the cover sits flat without sagging over the gunwales.
5. Fasten the rear straps under the transom or to the trailer, keeping tension even.
6. Check that the cover does not press on the windshield, antennas or any raised fittings.
7. Walk around the boat and tighten any loose straps, but avoid over-tightening, which can distort the fabric.

Securing Against Wind

Wind is the most common reason covers tear or lift off. Use all provided tie-down points and add straps or bungees at the midpoints if the boat is exposed. Many owners add a cable or lock through the bow eye to deter theft as well. Check straps after storms and after the first week of use, since fabric settles and straps can loosen.

Step 6: Maintain the Cover Through the Season

Good care extends the life of the cover. Brush off loose dirt, leaves and snow regularly, and never let heavy snow sit on the top for long periods. Clean the fabric with a mild soap and water solution and a soft brush, then rinse thoroughly and let it dry completely before folding. Avoid harsh solvents, pressure washers and bleach, which can break down coatings and fibers. Store the cover dry and folded loosely to prevent creases from becoming permanent weak points.

Step 7: Plan for Off-Season and Long-Term Storage

If you store the boat for several months, make sure the interior is dry and clean before covering. Place moisture absorbers or a small ventilation strategy inside the cabin area to reduce mildew. Check the cover periodically during storage, especially after heavy rain.

Common Mistakes

• Buying by length alone and ignoring beam or console height, which leads to tight spots or sagging.
• Covering a wet boat, which traps moisture and encourages mildew.
• Pulling straps too tight, which stresses seams and grommets.
• Leaving the cover on a trailer with a fabric edge touching the ground, where it can wear through.
• Ignoring vents in humid climates, which can cause condensation inside the cover.
• Skipping regular brushing of snow and debris, which adds weight and abrasion.

Tips for Longer Cover Life

• Keep a spare set of straps or buckles on hand, since small hardware is the first thing to fail.
• Use a soft pad or cover guard at the bow where the cover rests against the rail.
• Fold the cover loosely in the same creases each time to reduce stress points.
• Inspect seams and zippers each season and repair small tears before they grow.

FAQ

Do I need a cover that fits my exact model?

A model-specific cover usually gives the closest fit and the least flapping, but a semi-custom cover sized to your length and beam range can also work well if the shape is similar. Check the manufacturer’s size chart before buying.

How do I measure my Sun Tracker for a cover?

Measure overall length from bow tip to transom, beam at the widest point, and height to the highest fixed structure such as a console or T-top. Compare these to the cover’s listed ranges.

Should I put a cover on a wet boat?

No. Let the boat dry first, since trapped moisture can cause mildew and staining. Dry storage is always better for the hull and interior.

Does a sun tracker boat cover need vents?

Vents help in humid or coastal areas by allowing condensation to escape. In drier climates, a non-vented cover may be fine, but check the manufacturer’s recommendation for your region.

How do I keep the cover from blowing off?

Use all tie-down points, add ratchet straps or bungees at the midpoints, and check the tension after the first few days. Covers on exposed trailers or docks need extra attention in wind.

How often should I clean the cover?

Brush off debris regularly and wash the cover once or twice a season, or whenever dirt or mildew builds up. Always dry it fully before folding and storing.

Can I use a cover on a Sun Tracker with a trolling motor?

Yes, but the cover must have clearance for the motor and its mount. Measure the trolling motor’s height and position before choosing a size, and confirm the cover includes an opening or extra panel if needed.

Conclusion

A well-fitted sun tracker boat cover guards your boat against sun, rain and debris for years when you choose the right size, material and installation method. Measure carefully, follow the steps for securing the cover, and keep it clean and dry between uses. For storage that goes beyond a single season, consider a professional’s advice on winter preparation.
