Boat Deck Essentials: What You Need To Know

There are many things to consider when deciding what to put on a boat deck. Firstly, the type of boat and its primary use are important factors. For example, a deck boat prioritises function over form and offers more deck space, while a bowrider has a pointy-in-the-bow design and nimbler handling. The size of the boat is also crucial, as smaller boats may require different deck configurations to maximise space.

The materials used for the deck are another key consideration. Traditional wooden decks consist of planks laid over beams and carlins, with seams caulked and paid with tar. Modern constructed decks often use multiple layers of marine-grade plywood, covered with fibreglass and resin. Teak is a popular choice for yacht decking due to its durability, water resistance, and aesthetic appeal. Alternative materials such as synthetic teak, cork, bamboo, and EVA foam are also gaining popularity for their affordability, lower maintenance, and environmental benefits.

In addition to the decking material itself, other components can be added to the deck to enhance its functionality. For example, a casting deck can provide a raised platform for fishing, while deck furniture such as the ship's wheel, binnacle, and fife rails may be installed. The deck may also need to accommodate equipment such as lifeboats, the ship's wheel, and navigation stations.

When deciding what to put on a boat deck, it is essential to consider the specific needs and requirements of the boat's users, as well as any relevant safety regulations and guidelines.

Fibreglass

The process of building a fibreglass boat deck begins with a female mould. The mould is first sprayed with gelcoat, then fibreglass cloth is applied, and then resin is used to saturate or "wet out" the fibreglass. When the resin cures, you have a hull or a boat part. Structural reinforcements like stringers and bulkheads can be moulded separately and then fibreglassed to the part, or may in some cases be laid at the same time.

There are three types of resins: polyester, vinylester, and epoxy. Polyester resin is inexpensive and generally all-purpose, but it has low stretch properties so it is not used on modern high-performance boats. Vinylester resin has better stretch characteristics than polyester, so it more closely matches the strengths of exotic reinforcements. Epoxy resin is high-performance and will adhere better than any other resin to a wide range of materials, but it is hard to work with.

Teak wood

Teak is a popular choice of material for boat decks, especially for yachts. It is dense, moisture-resistant, and beautiful. When sealed, it can resist moisture, weather, and UV rays. It is also non-slip when wet, making it practical and safe for marine use.

However, teak is not without its drawbacks. It is expensive and does not last forever, especially if it is scrubbed regularly. It also absorbs heat from the sun, which can make it uncomfortable to walk on in bare feet. In addition, teak is not a sustainable choice, as it is sourced from rainforests in Myanmar, which has led to illegal logging practices.

There are different types of teak wood that vary based on the country of origin and quality. Here are some of the top types of teak wood used for boat decks:

• Bojonegoro teak: This is considered some of the finest teak in the world and comes from Indonesia. It has a rich golden colour and is usually straight-grained with medium spacing between grains. However, it is quite expensive, so it is mainly used in high-budget boat restorations.
• Banyuwangi teak: This type of teak is more affordable than Indonesian teak and primarily comes from India. While it has a less rich colour, it still possesses the desirable properties that make teak a wonderful decking material.
• Tectona grandis (common teak): This is the most common and affordable type of teak. It is usually farmed on plantations and is the best choice for environmental sustainability, as other types of teak are often harvested using unsustainable logging practices.

When choosing teak wood for your boat deck, it is important to be aware of marketing buzzwords and ensure that you are getting genuine, high-quality teak from a reputable supplier.

Cork

One of the biggest advantages of cork boat decking is its durability. Cork is highly durable and long-lasting, making it an excellent investment for boat owners. It is also easy to clean and maintain, which is essential for boat owners who want to spend more time enjoying their boats and less time on maintenance.

In addition to its practical benefits, cork is also an attractive and unique material that can enhance the look and feel of your boat. It has a natural look that will fit in with any colour scheme and can be customised with designs, logos, or images to make your boat truly one of a kind.

Whether you're looking for a safe, non-slip surface, a sustainable and environmentally-friendly option, or a unique and attractive design, cork boat decking is an excellent choice. With its combination of durability, traction, soundproofing, and insulation, cork can transform the look and feel of your boat while also providing practical benefits that will enhance your boating experience.

Bamboo

Choosing Bamboo

Treating Bamboo

To enhance the durability and moisture resistance of bamboo, several treatment options are available:

• Sealing: Apply a marine-grade sealant to the bamboo to create a protective barrier against water and moisture. This will help prevent rot and prolong the life of the bamboo deck.
• Oiling: Natural oils, such as linseed or tung oil, can be applied to bamboo to enhance its water resistance. These oils penetrate the bamboo fibres, making them less susceptible to moisture absorption.
• Varnishing: A marine-grade varnish can be used to create a durable, protective coating on the bamboo. This will add a glossy finish and provide additional protection against the elements.

Installing Bamboo Decking

When installing bamboo on a boat deck, it's important to follow these steps:

• Substructure: Ensure the boat's substructure, including beams and carlins, is sturdy and capable of supporting the bamboo decking.
• Frame: Construct a lightweight frame using marine-rated wood, such as white spruce. This frame should be custom-built to fit the contours of your boat, providing a stable base for the bamboo decking.
• Fitting: Cut the bamboo planks to size, ensuring a precise fit. Secure the bamboo to the frame using marine-grade adhesives and fasteners. Leave a small gap between planks to allow for expansion and contraction.
• Finishing: Finish the bamboo deck with a final coat of sealant or varnish to enhance its protection and appearance.

Maintenance

To ensure the longevity of your bamboo boat deck, regular maintenance is key:

• Cleaning: Use a mild detergent and soft-bristled brush to clean the bamboo deck regularly, removing any dirt, debris, or stains. Rinse thoroughly with fresh water.
• Re-oiling or Re-varnishing: Depending on the treatment used, re-apply oil or varnish as needed to maintain the bamboo's protection. This will help restore its water resistance and enhance its appearance.
• Inspection: Periodically inspect the bamboo for any signs of wear, rot, or loosening. Address any issues promptly to prevent further damage.

By following these steps and considerations, you can create a beautiful and functional bamboo boat deck that is both sustainable and durable. With proper care and maintenance, your bamboo decking will provide a natural and eco-friendly enhancement to your boat for years to come.

Eva foam

When purchasing EVA foam boat decking, it is essential to consider the size and shape of your boat deck. Measure the area where you plan to install the EVA foam and choose a product that best fits your dimensions. Some EVA foam decking options come in standard sizes, while others can be custom-made to ensure a perfect fit. It is also important to consider the thickness of the foam, as this can provide additional cushioning and comfort underfoot.

In addition to its functionality and aesthetic appeal, EVA foam boat decking is a popular choice due to its low maintenance requirements. Regular cleaning and proper care can help maintain the appearance and extend the lifespan of the decking. However, it is important to note that EVA foam may not have the same visual appeal as traditional wood decking or wood-like alternatives, such as teak or synthetic teak.

Overall, EVA foam is an excellent option for boat decking, especially for those seeking a practical, lightweight, and grippy material. With its variety of colours, patterns, and textures, EVA foam can enhance the functionality and style of your boat deck.
