Materials for Building a 2070 Jon Boat

Plywood Selection

For wooden jon boats, marine-grade plywood is preferred due to its water resistance, strength, and longevity. Typical requirements include:

• 1/2” Marine Plywood: For hull sides, bottom, and decking.
• 3/4” Marine Plywood: For transom and flooring where extra strength is needed.

Lumber and Framing

• Pressure-treated 2x4s or 2x2s for ribs, frames, and supports.
• Hardwood for gunwales and reinforcement areas.

Fasteners and Adhesives

• Stainless steel or bronze screws and bolts for corrosion resistance.
• Waterproof marine epoxy for bonding and sealing joints.
• Polyurethane sealant for watertight seams.

Fiberglass and Resin (Optional)

Fiberglass cloth and epoxy resin can be applied to the hull for added strength and waterproofing, though some builders skip this step for lightness and simplicity.

Paints and Finishes

• Marine-grade primer and topcoat for exterior protection.
• Non-slip deck paint for safety.

Additional Materials

• Marine-grade carpet or vinyl for comfort and aesthetics.
• PVC or aluminum trim for edges and rub rails.
• Hinges, handles, and latches for hatches and storage compartments.

Step-by-Step: Building the 2070 Jon Boat

1. Reviewing the Plans and Making Templates

Start by thoroughly reviewing your 2070 jon boat plans, cross-referencing each part with the materials list. Transfer the patterns to plywood using a pencil, ruler, and measuring tape. Accuracy at this stage ensures a smooth build and a professional result.

2. Cutting the Hull Components

Cut out the bottom panels, side panels, transom, and frames according to the plan measurements. Use a jigsaw or circular saw for straight, clean edges. Mark each part for easy assembly later.

3. Assembling the Frame

Lay out the bottom panel and attach the frames, ribs, and transom. Check for squareness using a framing square. Secure connections with marine epoxy and stainless screws. Temporarily brace the assembly until the adhesive sets.

4. Attaching the Side Panels

Position the side panels along the frames and bottom, clamping them in place. Fasten with screws from the bottom up, moving from bow to stern. Fill gaps with epoxy thickened with filler for a watertight seam.

5. Reinforcing Gunwales and Corners

Add hardwood strips along the top edge of the sides (gunwales) for added strength. Reinforce the corners and transom as specified in your plans, especially if you plan to mount a heavy motor.

6. Decking and Flooring

Install the deck, seats, and floor panels, ensuring all surfaces are flush and well supported. Create access hatches for storage and maintenance. Use stainless fasteners and waterproof glue for long-lasting joints.

7. Sealing and Waterproofing

Apply marine-grade epoxy to all seams, joints, and exposed plywood surfaces. If desired, cover the hull exterior with fiberglass cloth and resin for maximum protection. Allow all coatings to cure fully between coats.

8. Painting and Finishing

Sand the entire boat smooth to remove sharp edges and prepare for painting. Apply primer, then two to three coats of marine paint. Use non-slip paint or mats for the deck. Add vinyl or carpet for comfort and grip.

9. Adding Hardware and Accessories

Install cleats, handles, navigation lights, rod holders, and storage hatches. Fit the transom with a motor mount reinforced with additional plywood or metal if needed. Ensure all fittings are sealed against water intrusion.

10. Launch Preparation

Inspect all seams, fasteners, and hardware. Load the boat onto a trailer (verify local regulations regarding homemade vessels), and conduct a float test in shallow water before undertaking any long journeys.

Customizing Your 2070 Jon Boat

Seating and Storage

A 2070 jon boat’s wide beam provides flexibility for built-in benches, folding seats, or pedestal mounts. Consider adding under-seat storage or waterproof hatches for gear, bait, or emergency equipment.

Livewells and Bait Tanks

For anglers, custom livewells or bait tanks can be built into the deck using marine pumps and plumbing hardware. Ensure tanks are well-supported and properly sealed to prevent leaks.

Electronics and Lighting

Plan for navigation lights, fish finders, GPS units, and battery storage. Run wiring through conduit or under decking to protect it from water and mechanical damage.

Camouflage and Duck Blind Options

Waterfowl hunters often add removable blind frames and camouflage covers. Design these to be lightweight, stable, and easy to deploy. Use waterproof fabrics or natural materials for concealment.

Rod Holders and Tackle Stations

Install flush-mount or clamp-on rod holders along the gunwales for hands-free fishing. Dedicated tackle storage or workstations can be integrated into the deck or under seats.

Anchor and Mooring Systems

Add bow and stern cleats for anchoring, as well as anchor storage lockers or rollers for convenience. Consider a shallow-water anchor system for effortless positioning in calm waters.

Essential Safety Considerations

Flotation and Buoyancy

Include foam flotation blocks or chambers within the hull to keep your boat afloat if swamped. Check your plans for placement and amount of foam required to meet local or Coast Guard regulations.

Weight Distribution

Evenly distribute weight (passengers, batteries, fuel, gear) to maintain stability and ensure safe handling. Revisit your layout during construction to optimize balance and trim.

Proper Sealing and Drainage

All seams, screw holes, and hardware penetrations should be sealed with marine epoxy or polyurethane. Install a drain plug at the transom to remove water after use.

Personal Flotation Devices (PFDs) and Emergency Gear

No matter how stable your jon boat, always carry enough life jackets, paddles, signaling devices, and a first aid kit for all passengers.

Maintaining Your 2070 Jon Boat

Regular Inspection

• Check for cracks, leaks, or loose hardware before each trip.
• Inspect the transom for signs of rot, delamination, or stress (especially if mounting a heavy motor).
• Re-seal or touch up paint and epoxy as needed each season.

Cleaning Procedures

Rinse your boat with fresh water after each use, especially if exposed to saltwater. Use mild soap and a soft brush for stubborn stains. Remove deck carpets or mats to dry thoroughly and prevent mold.

Storage Tips

• Store your jon boat under cover or indoors to protect from weather.
• Ensure the hull is dry before covering to prevent mildew.
• Support the boat evenly to avoid warping or stress on the hull.
