A pontoon boat deck is a major component and it plays an important role in how the boat looks, feels, and performs. The deck provides structural support for the pontoon boat and its components. It also plays a role in the pontoon boat’s appearance.
Since the deck provides structural support for the pontoon boat, the deck must be sturdy, durable, and appropriate for the boats purpose. Additionally, pontoon boat decking is available in many different materials with various price points. The pontoon boat owner must select the best decking material that satisfies all these aspects: strength, durability, cost, maintenance, and usage.
This guide gives an in-depth review of pontoon deck materials, sizes, maintenance, and coverings.
Pontoon Boat Decking Materials
As previously mentioned, a pontoon boat’s deck is extremely important. The pontoon boat’s deck helps ensure a strong connection between the “toons”, and it serves as the foundation for seats, railings, Bimini tops, center console, etc.
Selecting the wrong decking material can result in poor boat stability, quick deterioration, and an overall bad experience. Therefore, the pontoon boat decking material must be strong, durable, water/rot resistant and easy to maintain. The following sections highlight the best pontoon boat decking materials.
Aluminum
Many pontoon boat manufacturers use aluminum as their decking material. Aluminum decks are among the strongest and most lightweight allowing better boat performance. Rot resistance is one of its outstanding properties. Rot resistance is an important quality and a major factor affecting all pontoon boat decking materials. Aluminum decks are easy to maintain and clean, and, with an anodized coating, have good fade resistance.
Unfortunately, aluminum decking is quite expensive. Also, aluminum does not insulate sound or heat making the pontoon boat very loud and hot to the touch. Due to the heat, its essential to cover the aluminum deck with quality pontoon boat flooring.
Wood
Wood pontoon boat decking comes in different species, qualities and costs. In general, wood is easy to work with, but may be heavier than other materials. Wood decking is available in rich and vibrant colors and is aesthetically appeasing. Some types of wood (teak and white oak) are rot resistant and quite durable, but also very expensive.
On the flip side, due to sun and water exposure, wood decking will lose its color and sheen over time. As a result, wood decking must be sanded and refinished every few years.
Marine-Grade Plywood
The marine-grade plywood is a good material for pontoon boats decking. It is strong and durable. It is also lightweight. Marine-grade plywood is made with waterproof glue, which increases its water and rot resistance. Pontoon decks made from marine-grade plywood are often long-lasting and can withstand tough environmental conditions.
Composite
Composite pontoon boat decking is lightweight, strong, durable, and requires almost no maintenance. The material may be a mixture of multiple substances such as wood, vinyl and plastic. Composite may develop mildew resulting in staining. Therefore, it requires cleaning and washing every few weeks. Composite decking lasts longer than wood and does not require refinishing. The major downside is composite decks are very expensive, and any damage requires repalcement.
Fiberglass
Fiber glass pontoon boat decking is some of the most durable, but it’s also expensive. It is water resistant and very easy to clean and maintain. It is easy to mold and perfectly fits any configuration. Being lightweight, fiberglass does not impact the pontoon boat’s speed and fuel economy.
However, it is prone to cracking, and repairing can be time consuming and difficult.
Pontoon Boat Deck Covering
Irrespective of the material used, pontoon boat decks are generally covered with a flooring material. We have an article that dives into the pontoon boat flooring options and helps you select the best. Additionally, we have a pontoon boat flooring buying guide that provides you the opportunity to purchase the flooring option you selected in the first article.
Pontoon Boat Decking Size
Selecting a pontoon boat deck size can be difficult. It’s important to know the number of passengers, and the size of the water body. Furthermore, the pontoon boat’s purpose is a big determinant of the deck size. There are certain sizes of pontoon decks available in the market. They all have different applications and suitability.
- 17′ to 19′: This is the perfect deck size for small gatherings between six to eight passengers. It’s perfect for calm and small bodies of water.
- 20′ to 22′: This deck size can accommodate twelve passengers. It is appropriate for small bodies of water like lakes and streams.
- Over 22′: These large decks are suited for cruising through difficult water and high waves, while providing sufficient room for up to 15 passengers.
Pontoon Boat Decking Maintenance
Improper maintenance leads to deterioration of all boat parts and components, and the deck is no different. The deck is an important part of pontoon boats, and therefore, requires constant non-negotiable maintenance. Some basic routine maintenance for pontoon decks include:
- Periodically brush clean to remove dirt. Also, a simple soap and water solution provide a quality clean.
- Water should not be left standing on teak floors as it can support mold and mildew growth.
- Avoid using acid to clean wood decks as it destroys the pulp and weakens wood’s water and UV-resistant properties.
- Promptly remove stains once detected because they will have less impact and they’ll be easier to remove.
