Adding A Casting Deck To Your Jon Boat

Jon boats are a popular choice for fishing enthusiasts due to their versatility and lightweight build. However, their small size can make casting a bit challenging. This is where a casting deck comes in – by creating an open space, anglers can cast more freely and accurately. In this article, we will discuss the steps to build a customised casting deck for your Jon boat, enhancing your fishing experience. From measuring the boat to cutting the deck material and treating the wood, we will guide you through the process of building a functional and stable casting platform.

Removing the front seats

If your seats are screwed in, you will need a power drill with the appropriate drill bit—either a Phillips or flat-head screw bit. If your seats are riveted, you will need a hole punch or a Phillips head drill bit that fits just inside the rivet.

If your seats are riveted, the first step is to punch out the centre hole of the rivet using a hole punch or a Phillips head screwdriver and a hammer. After creating the centre hole, dip your drill bit in some oil and drill out the rivet. Repeat this process for all the rivets holding the bench seats in place.

Once you have removed all the rivets, you can take out the front seats. You will likely notice the insulation underneath the seats, which helps the boat float in the event of an accident. It is important to replace this insulation when you install the frame for your casting deck. Use a lightweight insulation to ensure the boat remains buoyant.

After removing the seats, you will need to decide on the material for your casting deck frame. Most people use 2 x 4s, while others opt for steel or aluminium framing, which may require welding. Ensure that the front of the boat remains stable, and drill the frame to the sides of the boat to prevent the sides from flexing under the added weight of the fisherman. Depending on the size of your Jon boat, you may need a centre brace in the frame for additional support.

Choosing the right material

When it comes to choosing the right material for your casting deck, there are several options to consider. The most popular choices are plywood, aluminium, woodcore epoxy, and fiberglass. Here's a detailed overview of each option:

• Plywood: Plywood is a commonly used material for casting decks due to its lightweight and sturdy nature. It is relatively affordable compared to other options and comes in different thicknesses, allowing you to choose the desired weight and strength for your deck. However, standard plywood is not water-resistant and requires treatment to prevent rot and water absorption. Consider using marine-grade plywood or treating the plywood with paint, sealer, or a water-resistant coat. You can also encase it in flexible aluminium or use multiple coats of sealer to improve its durability.
• Aluminium: Aluminium is a versatile, lightweight, and durable metal that is widely used in various applications. It is strong, workable, and resistant to corrosion. Aluminium is a good choice for a casting deck as it can be shaped easily and provides sufficient support for an individual's weight. However, it requires proper treatment to withstand damp environments and prevent corrosion in saltwater. Regular cleaning, especially after saltwater fishing, is essential to maintain the longevity of the aluminium deck.
• Woodcore Epoxy: Woodcore epoxy combines the strength of wood, such as pine or oak, with the water-resistant properties of epoxy. It offers a natural wood finish and is highly customisable in terms of colours and finishes. Woodcore epoxy is easy to clean, maintain, and repair. While it may be slightly heavier than aluminium, it is a waterproof and aesthetically pleasing option for your casting deck.
• Fiberglass: Fiberglass, also known as glass-reinforced plastic (GRP), is an extremely lightweight material. It is easy to work with and can be cut into the desired shape without much trouble. Fiberglass is sturdy enough to support most people's weight and is inherently waterproof. However, it is prone to splintering, and proper care must be taken during handling to prevent irritation to the skin and eyes.

When selecting the material for your casting deck, consider factors such as weight, durability, water resistance, customisability, and ease of installation and maintenance. Additionally, ensure that the material you choose provides a stable platform and does not significantly alter the weight distribution of your Jon boat.

Measuring the boat

Before you start building a casting deck for your Jon boat, you need to measure your boat to know how big the raised deck will be. These dimensions don't need to be precise, but they will give you a general idea of the amount of material you will need.

The main thing you are trying to determine is how much plywood you will need to create the raised deck. Measure the widest point of where your casting deck will be. This will most likely be the width of the front bench or middle bench, depending on how big you want your casting deck to be. Then, measure from this seat to the front of the boat.

Check what standard sizes of plywood are available at your local hardware store. Ideally, you will want one continuous section of plywood as any seam will be a weak point and a place where water can seep through.

The easiest way to get the exact shape of the deck is to get a large piece of cardboard. Cut out a piece that is slightly smaller than the deck area and can easily fit inside the boat. Measure the length of the front bench and the bow, then measure the distance from the front of the boat to the seat. Use these to draw a trapezoid on the cardboard and cut it out. It's better if there is a gap on the sides as these will be filled. Place the cardboard into the boat and begin filling in the gap with smaller pieces of loose cardboard. Once you are happy with the fit, tape these sections to the large piece of cardboard to make an accurate template.

Place the template onto the plywood sheet and draw out the shape of the deck. There is a good chance that a standard sheet of plywood will be just a bit too small. If this is the case, mark out as much as you can, and the remainder can be filled in with some leftover plywood later.

Cutting the deck material

Firstly, you'll need to decide on the type of material you want to use for the frame. Most people use 2 x 4 wooden boards, but some opt for steel or aluminium framing, which may require welding skills or the assistance of a welding company. Ensure the frame is stable and securely drilled to the sides of the boat to prevent flexing under the weight of the fisherman.

Once the frame is in place, it's time to cut the platform material. The platform is typically made from 3/4-inch plywood, which needs to be cut precisely to fit over the frame. This is where your cutting skills come into play.

Before cutting, it's important to measure twice to ensure accuracy. Use a measuring tape or a ruler to mark the cutting lines on the plywood sheet. You can also snap a chalk line to ensure a straight cutting line.

For the cutting tools, you have a few options. A circular saw is a popular choice for long cuts, while a jigsaw with a coarse wood-cutting blade can be used for more intricate cuts. A miter saw is also useful for precise angle cuts. If you're cutting the plywood sheet after installing it, you can use a makeshift 'fence' or straight board as a guide for your saw to ensure a straight cut.

Safety should be a top priority when cutting. Wear eye protection and other necessary safety gear. Make sure your work area is clear of any obstacles, and be mindful of the cord if using a corded power saw.

Take your time with the cuts and double-check your measurements before proceeding. It's better to cut a little less than needed and adjust later than to cut too much and ruin your material.

Once the plywood platform is cut to size, you'll want to seal it with a waterproof coating to prevent water damage and rot. Follow the manufacturer's instructions for application and drying time.

Finally, consider adding a cover to protect the wood. Marine carpet or rubber sheeting are popular choices, offering both protection and a non-slip surface.

By carefully cutting and installing the deck material, you'll be well on your way to enjoying your new casting deck on your Jon boat.

Treating the wood

Once you have your wood, it's time to treat it. There are a variety of ways to do this, but the goal is to prevent the wood from rotting due to exposure to water. One option is to use a water sealant, such as Thompson's Multi-Surface Waterproofer. This product usually only needs one coat, but you can apply a second if water isn't beading and rolling off the surface after the first application.

Another option is to use a marine-grade paint or epoxy. You can also add sand to the wet paint to create a non-skid finish. If you go this route, be sure to use an oil-based paint and a moisture-resistant primer.

If you're using plywood, you can also seal the edges with an epoxy sealer paint. This will help protect the wood from water damage. Some people also recommend using an undercoating or truck bed liner before applying carpet or rubber sheeting.

Finally, consider the type of wood you're using. Marine plywood is not treated, so it will need to be sealed or coated to protect it from water damage. Treated plywood may have a negative reaction with the aluminum in your Jon boat, so it's best to avoid it. Instead, look for plywood with more ply layers and no voids, glued with moisture-proof/resistant glue.

By properly treating the wood, you can help ensure that your casting deck is durable and long-lasting.
