Why an 18 Ft Boat Cover Is Necessary
From my experience, having an 18 ft boat cover is absolutely essential for protecting my boat. It shields my boat from harsh weather conditions like rain, sun, and wind, which can cause fading, cracking, or even structural damage over time. Without a cover, my boat’s interior and exterior materials would wear out much faster.
I also find that using a cover helps keep my boat clean by preventing leaves, dirt, bird droppings, and other debris from accumulating. This saves me a lot of time and effort when it’s time to hit the water again, as I don’t have to spend hours cleaning before every trip.
Additionally, an 18 ft boat cover provides security by keeping my boat out of sight and making it less tempting to thieves or vandals. Overall, investing in a quality boat cover has given me peace of mind and extended the life of my boat significantly.
My Buying Guides on 18 Ft Boat Cover
When I decided to get an 18 ft boat cover, I realized there’s a lot more to consider than just size. To help you out, I’ve compiled everything I learned from my own experience to make sure you get the best protection for your boat.
1. Measure Your Boat Accurately
The first step I took was measuring my boat carefully. An 18 ft boat cover is designed for boats around 18 feet in length, but you should also consider the beam (width) and height of your boat. I recommend measuring from the tip of the bow to the stern, including any attachments like swim platforms or outboard motors if you want full coverage.
2. Choose the Right Material
Boat covers come in various materials, and I found that the choice depends on where and how you store your boat. Here are the common options I considered:
- Polyester: Durable and water-resistant, great for moderate weather.
- Polypropylene: Lightweight and breathable, good for preventing mildew.
- Canvas: Heavy-duty and offers great UV protection, ideal for long-term outdoor storage.
- Vinyl: Waterproof and easy to clean but can get hot under the sun.
For my boat, I went with a marine-grade polyester because it balanced durability and breathability well.
3. Consider the Type of Storage
Where you keep your boat impacts the kind of cover you need. I store my boat outdoors most of the time, so I needed a cover that could withstand sun, rain, and wind. If you keep your boat in a garage or under a covered dock, you might opt for a lighter cover or one that prioritizes dust protection rather than weatherproofing.
4. Look for UV Protection
Sun damage is a big concern, especially during long storage periods. I made sure the cover I bought had strong UV resistance to protect the gel coat and upholstery from fading and cracking.
5. Check for Waterproof and Breathable Features
Waterproof covers keep rain out, but I also wanted something breathable to prevent moisture from getting trapped underneath, which can lead to mold and mildew. A good cover balances both – waterproof on the outside, breathable on the inside.
6. Ease of Installation and Fit
I preferred a cover that was easy to put on and take off by myself. Look for features like elastic hems, adjustable straps, and buckles. These help secure the cover tightly so it doesn’t flap around in the wind. Some covers even come with storage bags, which I found very handy.
7. Durability and Warranty
Since a boat cover is an investment, I checked the warranty offered by the manufacturer and read reviews about the cover’s durability over time. My chosen cover came with a 3-year warranty, which gave me extra confidence.
8. Budget Considerations
Prices vary widely depending on material and features. I set a budget but was willing to spend a little more for quality since a good cover saves money by protecting my boat from damage.
9. Additional Features to Look For
- UV-treated thread: To prevent stitching from deteriorating.
- Reinforced corners: For extra durability where the cover experiences the most stress.
- Vents: To improve airflow and reduce condensation.
- Compatibility with your trailer: If you transport your boat often, make sure the cover fits well while on the trailer.
