Why a 21 Foot Boat Cover is Necessary
From my experience, having a 21 foot boat cover is absolutely essential to protect my boat from the elements. Whether I’m storing it outside or transporting it, the cover shields the boat from harmful UV rays, rain, dust, and debris that can cause wear and tear over time. Without it, the paint can fade, and the interior can get damaged by moisture or dirt.
I’ve also noticed that using a properly fitted cover helps keep animals and insects from nesting inside my boat when it’s not in use. This saves me from unpleasant surprises and extra cleaning before I hit the water again. Plus, a good cover reduces the chances of accidental scratches or dings during storage.
Overall, investing in a 21 foot boat cover has made a big difference in maintaining my boat’s appearance and value. It’s a simple step that gives me peace of mind knowing my boat is well-protected year-round.
My Buying Guides on 21 Foot Boat Cover
When I decided to buy a cover for my 21-foot boat, I realized there were several important factors to consider to ensure I got the best protection and value. Here’s what I learned and what helped me make the right choice.
1. Measure Your Boat Accurately
Before anything else, I measured my boat carefully from bow to stern. Since boat covers are sized based on length, it’s crucial to know the exact size. For a 21-foot boat, a cover labeled for 20-22 feet usually fits well. If your boat has a unique shape or additional accessories like a tower, consider those dimensions too.
2. Choose the Right Material
Boat covers come in various materials, and I found this decision impacts durability and protection:
- Polyester: Lightweight and affordable, good for mild weather.
- Polypropylene: Offers better breathability and mildew resistance.
- Vinyl or PVC-coated: Waterproof and excellent for heavy rain or snow, but less breathable.
I chose a heavy-duty, breathable fabric to protect my boat from UV rays and moisture without trapping condensation.
3. Consider Weather Conditions
Where you store your boat influences the cover type. Since I keep mine outdoors, I needed a cover that withstands sun, rain, wind, and even snow. Look for UV protection, water resistance, and strong seams if your boat will be exposed to harsh conditions.
4. Check for Fit and Security Features
A snug fit is key to preventing flapping and damage. I looked for covers with elastic hems, adjustable straps, and buckles to secure the cover tightly. Some covers come with reinforced corners and tie-down points, which help keep the cover in place during windy days.
5. Ventilation is Essential
I learned that poor ventilation causes mold and mildew. Covers with built-in vents or breathable fabric help moisture escape, keeping the boat dry underneath.
6. Ease of Use and Storage
I wanted a cover that’s easy to put on and take off. Lightweight materials and simple fastening systems made this task much easier. Also, having a storage bag included was a nice bonus for keeping the cover tidy when not in use.
7. Budget vs. Quality
While shopping, I balanced cost with quality. Cheaper covers can save money upfront but might wear out quickly. I invested in a mid-range cover that offered durability and good weather protection, which gave me peace of mind.
8. Reviews and Brand Reputation
Finally, I read user reviews and chose brands known for reliable boat covers. Hearing from other boat owners about fit, longevity, and customer service helped me narrow down my options.
Final Thoughts
Buying a 21-foot boat cover is about protecting your investment. By measuring carefully, choosing the right material, considering weather exposure, and ensuring a secure fit, you can keep your boat in top shape season after season. I hope my experience helps you find the perfect cover for your boat!
