How Long Does A Pontoon Deck Last?
Understanding a pontoon deck’s durability and care requirements is essential for owners looking to maximize their investment and enjoy many years of boating pleasure.
Key Takeaway
The lifespan of a pontoon deck depends on various factors, such as material, maintenance, and environmental conditions. A pontoon deck can last 10-20 years or even longer with proper care.
Summary
-
- Pontoon decks are crucial for the structural integrity and functionality of the boat.
- They are commonly made from aluminum, marine-grade plywood, or composite materials.
- Each material has its advantages and disadvantages:
- Aluminum: Lightweight, strong, corrosion-resistant (20-30 years lifespan), prone to dents.
- Marine Plywood: Affordable, easy to install (15-20 years lifespan), requires regular sealing.
- Composite: Excellent durability, low maintenance (25-30+ years lifespan), resistant to rot and splintering.
- Environmental factors like sunlight, saltwater, and temperature fluctuations can affect the deck’s lifespan.
- Regular cleaning, inspection, proper storage, and application of protective coatings are essential for maintaining deck longevity.
- Common issues include rot (plywood), corrosion (aluminum), and fading/warping (composite).
- Repairs are possible for minor damage, while extensive damage may necessitate replacement.
Pontoon deck boats are expected to last between 10 and 20 years. If subjected to impact, their aluminum hulls only dent rather than break or crack. On the other hand, the fiberglass hulls of other boats are prone to damage.
Is it possible to deck a pontoon boat? All of this requires solid pontoon boat decking. It is not possible if the deck is weak.
This makes it essential that we choose our pontoon boat decking materials wisely. Most pontoon boats are manufactured with an aluminum frame. On top of this frame is the ‘deck’. This is the base of the boat.
Why is a Pontoon Deck Important?
The deck of your pontoon provides your boat with its structure, and it must be solid and durable. Your boat will likely be under pressure from harsh winds and waves.
Your decking must be demanding to defend your boat against such harsh conditions. A solid deck makes for a solid boat. Additionally, a well-constructed pontoon deck enhances passenger safety, ensuring stability and reducing the risk of accidents.
The deck also plays a crucial role in the boat’s overall functionality and usability, supporting various activities such as fishing, lounging, and social gatherings.
High-quality materials like aluminum or marine-grade plywood are commonly used to withstand exposure to water and UV rays, preventing rot and degradation.
Investing in a robust pontoon deck not only extends the lifespan of your boat but also ensures enjoyable and worry-free outings on the water for years to come.
Factors Influencing Pontoon Deck Longevity
Materials Used in Pontoon Deck Construction

Most Common Questions
How long does a deck last?
If you take excellent care of your deck and give it all the necessary maintenance, it can last for 20+ years. That said, the exact amount of time a deck will last depends on the type of wood and various other factors.
How fast can a pontoon boat go?
Pontoon boats generally have a top speed of about 30 miles per hour. This does not make them ideal for any activity involving a high-speed level.
Pontoon boats can get more expensive engines or more than one to increase their speed, but this can be highly expensive.
Why should I buy a pontoon boat?
Pontoon boats are perfect for the calm waters of a lake or river. As mentioned earlier, their speed is slower than that of a fishing or skiing boat.
This allows a more relaxing, less intense, leisurely ride around the lake.
Do pontoons flip easily?
Because of their design, pontoon boats handle pretty well in windy conditions and choppy or rough water. Two hulls allow the boat to be more stable and sit atop the waves, while a mono-hull vessel sits in the waves.
For this reason, it is doubtful that your pontoon will flip, tip, or capsize.
Do you have to drain pontoons?
Not all pontoon boats have drain plugs. This design helps to make them air and watertight, meaning unless they get ruptured, they won’t get any water inside of them that would need draining.
It also means that should you get a leak, fixing it should be a lot easier.
Can you use composite decking on a pontoon boat?
That’s why it’s essential to have a professional installer fit composite decking for pontoon boats and run the installation process from start to finish.
And of course, only the more modern composite products with the fiberglass reinforcement are used as a standard.
What frame do you use for composite decking?
For this reason, you should use pressure-treated or extremely durable lumber. Composite materials, which are resistant to rot and moisture, can also be used as an alternative.
Is it worth buying a pontoon boat?
Regarding vehicles, both on land and on water, it’s generally accepted that their monetary value will depreciate shortly after purchase. Thus, a good investment requires getting a quality, reliable vehicle you can enjoy for years. That perfectly describes a pontoon boat investment.
Can I use regular wood for my pontoon deck instead of marine plywood?
Regular wood is not recommended for pontoon decks as it lacks the water-resistant properties of marine plywood. Regular wood can lead to rot and significantly shorten the deck’s lifespan.
How can I prevent my marine plywood deck from rotting?
Apply high-quality marine-grade sealants and ensure proper drainage on your pontoon boat. Regularly inspect and repair any damage to maintain the deck’s integrity and prevent moisture penetration.
What is the best way to clean an aluminum pontoon deck?
Use a mild soap and water solution with a soft brush to clean aluminum decks. Avoid abrasive cleaners that can scratch the surface. Rinse thoroughly and dry to prevent water spots and oxidation.
Do composite decks require any special maintenance?
Composite decks require minimal maintenance. Regular cleaning with soap and water is usually sufficient. Occasionally inspect for damage or fading and follow manufacturer guidelines for necessary treatments.
Final Thoughts
In conclusion, several critical factors come into play when considering the question, “How Long Does A Pontoon Deck Last?”
First, the material quality significantly impacts longevity; high-quality materials can ensure a pontoon deck lasts closer to the upper end of its typical 10-20-year lifespan.
Another determinant is the frequency of use; more frequent use will naturally accelerate wear and tear. Regular maintenance practices, such as cleaning and timely repairs, are essential in extending the deck’s life.
Environmental factors, including exposure to harsh elements like UV rays, rain, and saltwater, also affect the deck’s durability.
Furthermore, the type of use for leisurely family outings or rigorous commercial activities will influence the wear rate.
By understanding these variables, one can more accurately predict and manage the lifespan of a pontoon deck, potentially maximizing its lifespan through strategic choices and maintenance efforts.
