Why Choose a 2070 Plywood Jon Boat?

The popularity of the 2070 jon boat design is rooted in its versatility and practicality. With a length of 20 feet and a generous 70-inch beam, this model offers:

Superior stability – Perfect for fishing, hunting, and general recreation, especially with multiple passengers or heavy gear.
Shallow draft – Designed to navigate easily through shallow waters like rivers, lakes, and marshes.
Ample space – The wide beam and open layout accommodate storage, seats, livewells, and custom features.
DIY-friendly construction – Plywood construction offers strength, reduced cost, and ease of assembly for skilled and novice builders alike.

Plywood Jon Boats vs. Aluminum Jon Boats

Plywood jon boats are often compared to their aluminum counterparts. While aluminum boats offer durability and are maintenance-light, they are typically more expensive and less customizable. Plywood, on the other hand, is:

More affordable for DIY builds
Simple to repair or modify with common tools
Good insulator (quieter ride, less condensation)
Customizable – you can choose layouts, features, and finishes to suit your needs

Planning Your 2070 Plywood Jon Boat Build

Successfully building a 2070 plywood jon boat starts with careful planning and preparation. Here’s what you need to consider before cutting your first piece of wood:

1. Workspace

You’ll need a clean, level area large enough to accommodate the full length and width of your boat. A spacious garage, carport, or outdoor canopy can work well. Make sure you have adequate lighting and protection from the elements if building outdoors.

2. Tools and Safety Equipment

Measuring tape, pencils, straight edge
Jigsaw/circular saw and hand saw
Power drill and screwdriver set
Clamps (lots!)
Hand plane or sander
Personal protective equipment (gloves, goggles, ear protection)
Epoxy mixing supplies, paint brushes, rollers

3. Materials

Plywood – Marine-grade or high-quality exterior plywood (typically ½” and ¾” thickness)
Lumber – For framing, stringers, and transom reinforcement (Douglas fir, mahogany, or treated pine)
Epoxy resin and fiberglass cloth – Waterproofing and strengthening joints/seams
Fasteners – Stainless steel screws, bolts, and washers
Marine sealant and paint – For protection and finishing

4. Permits and Regulations

Check with local authorities about boat registration requirements, size limitations, and safety regulations in your area before starting your build.

Step-by-Step Guide to Building a 2070 Plywood Jon Boat

Let’s break down the construction process for your jon boat, following a traditional stitch-and-glue method commonly used in plywood boatbuilding. Always refer to your purchased plans for specific dimensions and steps.

1. Laying Out and Cutting the Plywood Panels

Begin by transferring the measurements or patterns from your boat plans onto the plywood sheets. Double-check all markings before cutting. Use a jigsaw or circular saw for smooth, accurate cuts. Label each panel as you go for easy assembly.

2. Assembling the Hull Sides and Bottom

Lay out the side panels on a flat surface. If your plans require scarfing or joining panels for extra length, align the seams carefully and join with epoxy and fiberglass tape. Next, attach the bottom panel in the same manner, ensuring a tight, flush fit. Temporary zip ties, wire, or clamps can hold panels together during this phase.

3. Stitch-and-Glue or Frame Assembly

In the stitch-and-glue method, “stitches” of copper wire or plastic ties hold the panels together while you apply epoxy resin and fiberglass tape to the seams, creating a strong, waterproof bond. Alternatively, some plans use a framed approach, where you build a wooden skeleton first and attach the plywood panels to the frame. Each method has its advantages, with stitch-and-glue typically being faster and lighter.

4. Installing Bulkheads, Frames, and Stringers

Follow your plans to install internal supports, such as bulkheads (vertical partitions), frames, and stringers (longitudinal supports). These elements add rigidity and shape to the hull. Use epoxy and screws for secure joints, and ensure all components are square and flush.

5. Reinforcing the Transom

The transom (rear end of the boat) bears the weight of your outboard motor and must be robust. Construct the transom from double or triple layers of plywood, bonded with epoxy, and reinforced with hardwood framing if specified. Pay extra attention to sealing and protecting this area from water intrusion.

6. Glassing and Sealing the Hull

Once the basic hull structure is complete, apply a layer of fiberglass cloth to the bottom and sides, saturating with epoxy resin according to your plan’s instructions. This step provides abrasion resistance and ensures a watertight seal. Allow ample drying and curing time before proceeding.

7. Flipping the Hull and Adding Decks

With the hull cured, carefully flip it upright. Install the foredeck, side decks, and any interior features such as benches, storage compartments, or livewells. Secure all fittings with marine-grade hardware and seal with epoxy or marine caulk.

8. Fairing, Sanding, and Finishing

Fill any gaps or imperfections with epoxy fairing compound, then sand the hull smooth. Apply primer, then several coats of marine paint or varnish for long-lasting protection and an attractive finish. Non-skid decking paint can be added to walking surfaces for safety.
