Why a 21 Foot Boat Cover Is Necessary
From my experience, having a 21 foot boat cover is absolutely essential to protect my investment. Whether I’m storing the boat for a few days or several months, the cover shields it from harsh weather elements like rain, sun, and wind. Without it, my boat’s interior and exterior would quickly suffer from UV damage, fading, and water buildup that can lead to mold or mildew.
I’ve also found that a properly fitted cover keeps dirt, leaves, and debris from accumulating on my boat, saving me time and effort on cleaning. It acts as a barrier against pests and prevents unwanted critters from making my boat their home. Overall, using a 21 foot boat cover helps me maintain my boat’s appearance and functionality, ensuring it’s always ready for my next adventure on the water.
My Buying Guides on 21 Foot Boat Cover
When I was searching for the perfect cover for my 21-foot boat, I realized how important it is to choose the right one to protect my investment. Here’s what I learned and what I’d recommend considering if you’re in the market for a 21 foot boat cover.
1. Measure Your Boat Accurately
Before anything else, I made sure to measure my boat precisely from bow to stern. A 21-foot boat cover needs to fit snugly but not be too tight. I measured the length along the centerline and also took note of the beam (width) to ensure the cover would fit comfortably over the widest part.
2. Material Matters
The material of the cover plays a huge role in how well it protects your boat. I chose a cover made from heavy-duty polyester with a waterproof coating because it shields against rain, UV rays, and mildew. Some covers are made with breathable fabric, which I found helpful to prevent moisture buildup underneath.
3. Consider the Cover Type
There are different types of covers, such as full covers, cockpit covers, and shrink-wrap. Since I wanted full protection during off-season storage, I opted for a full cover that covers the entire boat. For quick trips, a cockpit cover can be handy, but it doesn’t protect the whole boat.
4. Check for UV Protection
My boat spends a lot of time outdoors, so UV protection was a must-have feature. Prolonged sun exposure can fade paint and damage upholstery, so I looked for covers with high UV resistance to keep my boat looking new.
5. Look for Easy Installation Features
I appreciated covers that came with elastic hems or adjustable straps. These features made putting on and securing the cover much easier, even when I was alone. Some covers also have zippers or vents, which help with ventilation and ease of access.
6. Durability and Warranty
Since a boat cover is an investment, I wanted one that would last multiple seasons. I checked reviews for durability and chose a brand that offered a good warranty. This gave me peace of mind in case of defects or early wear and tear.
7. Price vs. Quality
While I was tempted by cheaper options, I learned that investing a bit more upfront in a quality cover saves money in the long run by preventing damage to the boat itself. I balanced my budget with quality features to get the best value.
8. Seasonal vs. Year-Round Use
I thought about how often I’d be using the cover. If you only need it for winter storage, a heavier, more protective cover might be best. For year-round use, a lighter, breathable cover that handles rain and sun well is ideal.
Final Thoughts
Choosing the right 21 foot boat cover isn’t just about size—it’s about protection, durability, and convenience. By taking the time to measure carefully and consider materials and features, I found a cover that keeps my boat safe from the elements and makes my boating experience worry-free. I hope my guide helps you find the perfect fit for your boat too!
