Boat Cover Sizing Guide — Protect Your Investment in Any Water

Boat covers are the trickiest protective covers to size correctly. Windshields, T-tops, towers, outboard motors, and trailer configurations all affect fit. Here’s how to get it right.

Step 1: Measure Your Boat

For a trailerable cover, measure:

• Centerline length: Bow to stern along the center (not including swim platform)
• Beam width: Widest point of the hull
• Height: Gunwale to top of windshield or T-top

Step 2: Type of Cover

• Mooring covers: Snaps directly to the boat, stays on in water. Custom-fit to your exact hull.
• Trailerable covers: Designed for highway speeds. Heavier fabric (600D+) with reinforced tie-down points.
• Storage covers: Lightweight, for indoor or covered dock storage. Breathable fabric prevents mildew.

Step 3: Account for Accessories

Add 6-12 inches to your measurements for: outboard motors, swim platforms, bow rails, T-tops and towers, downriggers and rod holders.

Material Choices

Marine-grade polyester with solution-dyed UV treatment lasts 5-7 years outdoors. This is the standard for serious boat protection. Acrylic blends offer better breathability for high-humidity storage. PVC-coated polyester is the heavy-duty option for extreme weather.
