2070 Aluminum Jon Boat Plans

The 2070 Aluminum Jon Boat is a large, stable, and durable utility boat designed for fishing, transport, recreational use, and demanding work on lakes, rivers, and sheltered coastal waters. Its wide hull, spacious cockpit, and strong welded-aluminum structure provide excellent carrying capacity and generous working space.

The hull features a moderate 5° deadrise, combining the stability and shallow-water capability of a traditional jon boat with improved handling in light chop. Designed for outboard engines from 40 to 115 HP, this boat can carry up to five persons and offers a maximum displacement of approximately 2,910 lbs (1,320 kg).

Aluminum Construction

Construction Method

The hull is designed for fully welded aluminum construction and is assembled in an upside-down configuration. Building the hull upside down helps maintain accurate alignment of the frames, longitudinals, bottom panels, and side plates during fitting and welding.

The heavy-duty keel and transom structure provide additional strength for larger outboard engines and demanding operating conditions. Internal frames and longitudinal stiffeners support the hull plating and create a rigid, durable structure suitable for regular fishing and utility use.

Difficulty Level

Difficulty level: Medium.

This project is recommended for builders with basic aluminum fabrication and welding experience. Accurate measuring, plate fitting, tack welding, distortion control, and continuous aluminum welding are required during construction.

The design is suitable for a properly equipped home workshop or professional fabrication shop with the tools required for cutting, fitting, and welding marine-grade aluminum.

Large and Practical Interior

The wide hull and long cockpit floor provide useful space for passengers, fishing equipment, cargo, and optional interior components. The boat can be configured for recreational fishing, transport, general utility work, or a custom console layout.

Its combination of a wide chine, shallow draft, and moderate deadrise makes the 2070 a practical choice for users who need both stability and carrying capacity without moving to a deep-V hull.

Perfect For

• Fishing on large lakes and rivers
• Recreational boating for up to five persons
• Light commercial and utility work
• Transporting equipment and cargo
