Aluminium jon boats are a popular choice for fishing and hunting due to their flat-bottomed design, which makes them ideal for navigating shallow waters. They are also lightweight, easy to transport, and affordable. However, jon boats are not suitable for rough waters as they tend to sit on top of the water rather than cruising through it.
The basic parts of a jon boat include the hull, ribs, and bench seats. The hull is nearly flat, with a square bow, and can be made of aluminium, fiberglass, or wood. The ribs are exposed, but many individuals choose to cover them to create a flat, level surface. The bench seats are usually built-in, but some boats may have swivel seats or jump seats.
In addition to the basic parts, jon boats may also have live wells/bait wells, side or centre consoles, factory-installed decks and floors, electrical wiring, accessory pads/mountings, and casting or poling platforms. These parts can be purchased as upgrades or added through customisation.

What You'll Learn
Hull construction and materials
Jon boats are typically constructed from aluminum, but fiberglass and roto-molded polyethylene models are also available. Aluminum is an ideal material for jon boats due to its light weight, strength, and resistance to corrosion.
When it comes to aluminum alloys for boat construction, the Aluminum Association of the United States has developed a naming system, with over 500 registered designations. Of these, four alloys are most commonly used in the marine industry: 5052, 5083, 5086, and 6061. These alloys have a heat number of H3, indicating they have been strain-hardened and stabilized.
All 5000 alloys, including 5052 and 5083, use magnesium as the principal alloying element, making them easier to weld. 5052 is generally used for interior parts of the boat, such as cabins, decks, and gunwales. It is the "softest" of the four alloys and is less susceptible to cracking during the forming process. 5083, on the other hand, is stronger and widely used in marine environments where corrosion resistance is crucial. It can also withstand extremely cold temperatures without becoming brittle. 5086 is considered superior for marine environments due to its increased corrosion resistance, especially in saltwater. 6061 is a general-purpose alloy used for structural components and has excellent finishing characteristics.
The construction process for aluminum boats involves router-cutting alloy plates to exact dimensions and spot-welding them together. The boat is then placed on a full-scale jig for welding. The sides, bottom, gunwale, frames, self-bailing deck, and gunwale-deck are all welded using the best materials and technologies available. An aluminum internal fuel tank is placed beneath the deck, providing an additional safety measure.
To ensure unsinkability, pressurized closed-cell foam is injected into the below-deck cavities. The boat is then placed in a wash booth to remove smoke and residue from the welding process. After this, a non-skid deck coating is applied, and the boat is readied for rigging. Finally, components such as the steering system, navlight system, cushions, glass, electronics, and engines are installed.
In addition to the hull construction and materials, jon boats are known for their flat or nearly flat bottoms and squared-off bows. They are simple and utilitarian, often featuring bench seats. Jon boats are small, light, and inexpensive, making them a popular choice for fishing and hunting.

Engine type
Aluminum jon boats are versatile vessels that can be used for fishing, hunting, or cruising on small bodies of water. When choosing an engine type for your jon boat, you have three main options: gas, electric, or trolling motors. Each type has its own advantages and considerations, and the right choice will depend on your specific needs and preferences.
Gas motors are a reliable choice for jon boat owners as they offer a wide range of power options, typically ranging from 2.5 HP to 300 HP or higher. This makes them suitable for various activities, including hauling multiple people and their gear. Gas motors are usually heavier than electric options, and they may be more prone to mechanical issues due to their complex internal components. However, they are a good choice if you want decent speed and don't mind the extra weight.
Electric jon boat motors provide a best-of-both-worlds solution, combining the power of a gas motor with the quietness and low maintenance of a trolling motor. They are much more powerful than trolling motors, making them suitable for use as a primary source of power. Electric motors are also quieter and less smelly than gas engines, and they are easier to start. If you want enough power to navigate through inclement weather and reach your destination quickly, an electric motor is a good option.
Trolling motors are small electric motors that are silent, smooth, and easy to operate. They are a popular choice for jon boat owners, especially in lakes and communities that don't allow gas-powered motors. Trolling motors are ideal for small, calm lakes or navigating close to shore. However, they are not designed for cruising at high speeds, especially for larger jon boats over 12 feet in length.
When choosing an engine type for your aluminum jon boat, consider factors such as your intended activities, the size and weight of your boat, the type of waterways you'll be navigating, and your preference for speed and power. Additionally, factors like maintenance, fuel consumption, and cost may also influence your decision. Remember to choose an engine that aligns with your specific needs and budget to ensure an enjoyable and safe boating experience.

Boat flooring and decking
The flooring and decking of a jon boat can be made from a variety of materials, each with its own advantages and disadvantages. Here are some of the most common options:
Plywood
Plywood is a popular choice for jon boat flooring because it is cheap, lightweight, and durable. It can be painted or carpeted to match the desired aesthetic and is easy to work with. Plywood can be fastened to the ribs of the boat using bolts, washers, and rivnuts/nutserts, ensuring that it does not move or vibrate. This creates a sturdy and secure floor that can withstand the weight of a longtail mud motor.
Aluminum Sheet Metal
Aluminum sheet metal is another option for jon boat flooring and decking. It is important to use the correct type of aluminum to prevent degradation in saltwater. The recommended type is T6061 aluminum, which may need to be specially ordered. The thickness of the sheet metal will depend on the intended use and the amount of support underneath. For most applications, 1/8" thick metal is sufficient, but for greater stability, some people choose to use thicker metal such as 1/4" or even 1/2".
Extruded Polystyrene (XPS) Foam
Extruded polystyrene (XPS) foam, also known as styrofoam, is often used as a base layer for jon boat flooring. It is important to use XPS foam rather than expanded polystyrene (EPS) foam, as XPS does not soak up water or crumble easily. XPS foam can be purchased at most hardware stores and cut to size using a utility knife or hot foam cutter.
Mats
There are several types of mats that can be used for jon boat flooring, including horse mats, gym mats, and rubber mats. Mats can be easy to clean and provide a comfortable, squishy surface to stand on. However, they may not be the best option for hot climates, as the dark color of rubber mats can absorb heat. Additionally, mats may not be suitable for tying down heavy equipment such as mud motors.
EVA Foam
EVA foam is a popular choice for boat flooring and decking due to its non-slip properties and self-adhesive backing. It is available in a variety of colors and patterns, including faux teak, camo, and diamond patterns. EVA foam is easy to install and can be cut to fit the unique shape of a jon boat. It is a lightweight and comfortable option for boat flooring.
