The Best Boat Covers for Long-Term Storage

Josh Summerhays • December 15, 2025

When it comes to protecting your boat during long-term storage, a quality cover is one of the most important investments you can make. Whether you're storing your boat outdoors or under a canopy, the right cover can help prevent damage from UV rays, moisture, debris, and pests.


At Simply Storage, we know how important it is to protect what matters most. Here's what to look for in a boat cover, plus a breakdown of some of the best options for long-term storage.


What to Look for in a Long-Term Boat Cover


Not all boat covers are created equal. When selecting one for storage, keep these key features in mind:

  • Material Durability: Look for heavy-duty, marine-grade polyester or canvas. These materials resist tearing, UV rays, and mildew.
  • Water Resistance: A good storage cover should be water-resistant or waterproof to protect against rain and condensation.
  • UV Protection: UV rays can cause fading and cracking. Choose a cover with built-in UV inhibitors.
  • Proper Fit: A snug, tailored fit prevents sagging and keeps out pests, dirt, and moisture.
  • Ventilation: Look for covers with built-in vents to reduce mold, mildew, and condensation buildup. Proper ventilation matters because it helps reduce moisture buildup, which is one of the main causes of mold and mildew during storage.
  • Straps and Reinforcements: Covers with reinforced corners and adjustable straps will stay secure during wind and weather.
